Why print(a++) has syntax errors in python, but not print(++a) : <p>I am a beginner in python and I am using Python 3.5. The python console complains invalid syntax for the below statement:</p>
<pre><code>a = 5
print(a++)
</code></pre>
<p>But <code>print(++a)</code> works fine. Can anyone help me understand the difference?
Btw, it seems that <code>print(a+=1)</code> also doesn't work.
Thanks!</p>

How to set layer-wise learning rate in Tensorflow? : <p>I am wondering if there is a way that I can use different learning rate for different layers like what is in Caffe. I am trying to modify a pre-trained model and use it for other tasks. What I want is to speed up the training for new added layers and keep the trained layers at low learning rate in order to prevent them from being distorted. for example, I have a 5-conv-layer pre-trained model. Now I add a new conv layer and fine tune it. The first 5 layers would have learning rate of 0.00001 and the last one would have 0.001. Any idea how to achieve this?</p>

Send request over WiFi (without connection) even if Mobile data is ON (with connection) on Android M : <p>I have to send UDP packets to a WiFi module (provided with own AP) with no internet connection but when I connect the mobile with the AP, Android redirects my packets on the mobile data interface because it has got internet connection.</p>

Now i have tried to convert these date values into mmm-yy format as date values. So, I have used as.yearmon() function. After converting i have checked the details. I came to know that for the date values of 01-01-2016 from 12:00 AM to 05:28 AM i am seeing the values as Dec-15 which is wrong.
Kindly, help me to figure out the issue.

python 3 simple calculator , need assistance understanding subject and completing task, new to python and coding in general : <p>I need help programming a simple python 3 calculator, I am completely new to coding and python so my knowledge on this is low and i'm having a tough time just getting started. </p>
<p>heres the problem: Your assignment is to create an extremely simple calculator in Python. So simple, it can only add positive whole numbers.</p>
<p>Take a look at the hello.py example posted this week. It shows examples of reading data using the input() method. It shows how to write functions (using 'def'), as well as passing parameters and returning a value. It also shows how to interpolate variables into a string using the printf-style string formatting.</p>
<p>First create, a simple function called "add". It should take in two values and return the sum of the values.</p>
<p>Next create an interactive script which uses the "add" function. The output, when done, should look like this:</p>
<p>What is the first number?
3
What is the second number?
5
Your sum is 8.</p>
<p>In the example above, the bold items are typed by the user. Note that, to pass the online test, you must format your text exactly the same as above.</p>
<p>When done (and tested locally), test and submit online at CSGrading.com Assignment 2. </p>
<p>HELLO.PY CODE</p>
<pre><code>def get_firstname():
print("First Name: ")
firstname = input()
return firstname
def get_lastname():
print("Last Name: ")
lastname = input()
return lastname
def say_hello(f,l):
print("Hello %s %s" % (f,l))
say_hello(get_firstname(),get_lastname())

Image processing in Android/Java : <p>I was working on a project name symptom based disease diagnosis in android.
As android is java based, so I am implementing the the color matching algorithm directly in java first using image processing libraries like OpenCV etc. I was wondering if I completed the matching process and after that when I embed it into my android code, what if it didn't embed? That's why I am posting this question if I am going right with FIRST developing method in java then embed it into android or should I continue it directly with android??</p>

I dont understand the workflow of a program : #include <iostream>
int main() {
int nr;
std::cin>>nr;
while (nr > 0) {
int digit = nr % 10;
nr /= 10;
std::cout<<digit;
}
return 0;
}
Can someone please explain the workflow of this program, basically with the input "32" it outputs "23", that is good, thats my goal, my question is, why does it say "23" instead of just "2", why is the "3" being added in the end if i only said "cout digit". I get that the "3" comes from " nr /= 10", but why is it being outputed near the "2" to farm the answer "23"? | 0debug |

Regex - extract word from www.anything.com : <p>I am trying to use Regex to match a word within a www URL. In the event that the www does not exist, I would still like it to match on the '.com'. For example if the following text was present...</p>
<p>www.<strong>anything</strong>.com</p>
<p><strong>anything</strong>.com</p>
<p>It would return "<strong>anything</strong>" as the result. In the event that the 'www' is not present, it could still get it from the word before '.com'. But if the 'www' is present, I would like it to look there first. </p>
<p>Any thoughts?</p>

Flattening arbitrarily deep nested lists : <p>I want to retrieve data from n nested lists in Python. That is:</p>
<pre><code>[[[[[1, 2]]]]] => [1, 2]
</code></pre>
<p>I could obviously do something like:</p>
<pre><code>mylist[0][0][0][0]
</code></pre>
<p>But I'm wondering if there is a way to do this without having to know how deep the nesting of the list is. </p>
<p>I want to do this because I have got some fairly malformed data from a REST API request which needs processing. </p>

How to set a different namespace for child helm charts? : <p>When you install a chart with a child chart that doesn't specify a namespace, Helm will use the one specified on command line via <code>--namespace</code>. Is it possible to override this flag for a specific child chart? </p>
<p>For example if I have chart A which depends on chart B and I specify <code>--namespace foo</code>, I want to be able to customize the resources of chart B to be installed into some other namespace <code>bar</code> instead of <code>foo</code>.</p>

System.out.print( "Enter a five digit integer: " );
number = input.nextInt();
digit1 = number / 10000;
digit2 = number % 10000 / 1000;
digit3 = number % 10000 % 1000 / 100;
digit4 = number % 10000 % 1000 % 100 / 10;

Getting Action Cable to broadcast in Sidekiq Job : <p>I'm using Rails 5 in a docker environment and I can get Action Cable to broadcast on a Sidekiq worker perfectly fine, using worker.new.perform. </p>
<p>But for the life of me, I cannot get it to broadcast while using worker.perform_async.</p>
<p>Here is my cable.yml:</p>
<pre><code>default: &default
adapter: redis
url: <%= ENV['REDIS_PROVIDER'] %>
development:
<<: *default
test:
<<: *default
production:
<<: *default
</code></pre>
<p>Here is my worker:</p>
<pre><code>class AdminWorker
include Sidekiq::Worker
def perform
ActionCable.server.broadcast 'admin_channel', content: 'hello'
end
end
</code></pre>
<p>My Admin Channel:</p>
<pre><code>class AdminChannel < ApplicationCable::Channel
def subscribed
stream_from "admin_channel"
end
def unsubscribed
# Any cleanup needed when channel is unsubscribed
end
end
</code></pre>
<p>As I mentioned earlier, this works just fine when calling AdminWorker.new.perform. As soon as I try to run AdminWorker.perform_async, the cable will not broadcast and nothing helpful regarding action cable in the logs. What am I missing here?</p>

Google Fit SessionsApi not returning all sessions in time range : <p>Somehow I've run into a dead end with the Google Fit Android SDK. Currently I'm building an application that reads, displays and processes data from Google Fit to give users insights on their workout behavior. </p>
<p>My situation is as follows: I used to test on a Google Pixel - everything was fine and I've received all (more than 20) sessions from Google Fit. One week ago, I've switched to a HTC10 - on this device I'm only receiving 4 (!) sessions from Google Fit - same app, same code, same Google Fit account (in the Google Fit app
I can still see all workouts and sessions). The sessions I'm trying to read were not created with my app, but instead with the Google Fit app itself. But still, on the old phone I could read them, on the new one I can not. </p>
<p>Let me paste some code for additional clarity. </p>
<p>GoogleApiClient Set-Up</p>
<pre><code>googleApiClient = GoogleApiClient.Builder(context)
.addApi(Fitness.HISTORY_API)
.addApi(Fitness.SESSIONS_API)
.addApi(Fitness.RECORDING_API)
.addApi(Fitness.GOALS_API)
.addScope(Scope(Scopes.FITNESS_ACTIVITY_READ_WRITE))
.addScope(Scope(Scopes.FITNESS_BODY_READ_WRITE))
</code></pre>
<p>After connecting, I subscribe to several RecordingApis (<code>TYPE_WORKOUT_EXERCISE</code>, <code>TYPE_WEIGHT</code>, <code>TYPE_CALORIES_EXPENDED</code>)</p>
<p><code>SessionReadRequest</code>:</p>
<pre><code> val sessionRequest = SessionReadRequest.Builder()
.setTimeInterval(startTime, endTime, TimeUnit.MILLISECONDS)
.read(DataType.TYPE_WORKOUT_EXERCISE)
.readSessionsFromAllApps()
.enableServerQueries()
.build()
</code></pre>
<p>Reading the sessions:</p>
<pre><code> Fitness.SessionsApi.readSession(googleApiClient, sessionRequest)
.setResultCallback { result ->
Timber.d("Sessions result: %s", result.status)
Timber.d("Got %d sessions", result.sessions.size) // returns only 4! for 2014-NOW timerange
}
</code></pre>
<p>Any help would be appreciated.</p>

Multiplocation 2 two numbers : I have an assignment to build a function that multiplies 2 numbers ( int and double ) and without using * or '-'
Can only use '+' '/' and '%'.
I noticed alot of people are using shifting methos but i cant use without because we didnt learn it yet.
And as much as i can do it without 1 while loop easily the trick is its supposed to be in nlogn or logn runtime efficiency...
No list no arrays either though i dont see any way of using them anyway.
Is there any possible way of doing it ???
Thanks

Edittext imeOptions actionDone not working with digits attribute? : <p>I have an Editext . It contains attribute digits and imeOptions (actionDone) together. </p>

<p>The actionDone (Done button in Softkeyword) not found while using digit && imeOptions attributes together . We can only find enter button which doesn't make any focus change. I have tried it by skipping digit attribute , then imeOptions working correctly.

How google tracks me without using mobile my internet data plan? : I'm developing an app that can shows all the bus lines in my city, i'd like to show if the bus is crowed or not, and even get the bus position by another user that is inside it.
But I don't want to use all the internet plan from my users, i see that google does that, he know when a restaurante or bar has people there, knows if a street is congested, and also get your path history.
I'm not asking for all the code, but kind of how does google does that? | 0debug |

update dart sdk for flutter : <p>I would like to use dart SDK >= 2.2.0 with flutter. But my current version used BY Flutter is 2.1.2</p>
<pre><code>flutter --version
Flutter 1.2.1 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 8661d8aecd (2 months ago) • 2019-02-14 19:19:53 -0800
Engine • revision 3757390fa4
Tools • Dart 2.1.2 (build 2.1.2-dev.0.0 0a7dcf17eb)
</code></pre>
<p>I tried to install the 2.2.0 version independently and I succeed :</p>
<pre><code>dart --version
Dart VM version: 2.2.0 (Tue Feb 26 15:04:32 2019 +0100) on "macos_x64"
</code></pre>
<p>However, Flutter doesn't use this version as you can see above. I tried to replace files of the <code>dart-sdk</code> used by flutter (<code>flutter/bin/cache/dart-sdk</code>) by the version that I installed independently, but when I try to run Flutter after that I have a snapshot problem so I have put back the original <code>dart-sdk</code> folder in the flutter directory.</p>
<p>Do you have any ideas how can I update it? </p>
<p>PS: I downloaded flutter very recently (10 days ago) from here: <a href="https://flutter.dev/docs/get-started/install/macos" rel="noreferrer">https://flutter.dev/docs/get-started/install/macos</a></p>

Visual Studio Code debugging Array evaluation : <p>I have a small issue when debugging PHP with Visual Studio Code.
The XDebug works fine, I am able to stop at breakpoints and evaluate variables by hovering on them or adding them to watch.
However when I attempt to view an array which has more than 32 items, I can only see those first 32. For example, an array of 172 items will only display 32 items.
I tried to evaluate this array in a manner of ways, running dump commands inside the console, or json_encode, to no avail. </p>
<p>Any ideas?</p>

Is it better to use path() or url() in urls.py for django 2.0? : <p>In a django online course, the instructor has us use the <code>url()</code> function to call views and utilize regular expressions in the urlpatterns list. I've seen other examples on youtube of this.
e.g.</p>
<pre><code>from django.contrib import admin
from django.urls import include
from django.conf.urls import url
urlpatterns = [
path('admin/', admin.site.urls),
url(r'^polls/', include('polls.urls')),
]
#and in polls/urls.py
urlpatterns = [
url(r'^$', views.index, name="index"),
]
</code></pre>
<p>However, in going through the Django tutorial, they use <code>path()</code> instead e.g.:</p>
<pre><code>from django.urls import path
from . import views
urlpatterns = [
path('', views.index, name="index"),
]
</code></pre>
<p>Furthermore regular expressions don't seem to work with the <code>path()</code> function as using a <code>path(r'^$', views.index, name="index")</code> won't find the <code>mysite.com/polls/</code> view. </p>
<p>Is using <code>path()</code> without regex matching the proper way going forward? Is <code>url()</code> more powerful but more complicated so they're using <code>path()</code> to start us out with? Or is it a case of different tools for different jobs?</p>

Non-terminal forEach() in a stream? : <p>Sometimes when processing a Java stream() I find myself in need of a non-terminal forEach() to be used to trigger a side effect but without terminating processing.</p>
<p>I suspect I could do this with something like .map(item -> f(item)) where the method f performs the side effect and returns the item to the stream, but it seems a tad hokey.</p>
<p>Is there a standard way of handling this?</p>
