How do I remove 'None' items from the end of a list in Python : <p>A have a list that might contain items that are None. I would like to remove these items, but only if they appear at the end of the list, so:</p>
<pre class="lang-py prettyprint-override"><code>[None, "Hello", None, "World", None, None]
# Would become:
[None, "Hello", None, "World"]
</code></pre>
<p>I have written a function, but I'm not sure this is the right way to go about it in python?:</p>
<pre class="lang-py prettyprint-override"><code>def shrink(lst):
# Start from the end of the list.
i = len(lst) -1
while i >= 0:
if lst[i] is None:
# Remove the item if it is None.
lst.pop(i)
else:
# We want to preserve 'None' items in the middle of the list, so stop as soon as we hit something not None.
break
# Move through the list backwards.
i -= 1
</code></pre>
<p>Also a list comprehension as an alternative, but this seems inefficient and no more readable?:</p>
<pre class="lang-py prettyprint-override"><code>myList = [x for index, x in enumerate(myList) if x is not None or myList[index +1:] != [None] * (len(myList[index +1:]))]
</code></pre>
<p>What it the pythonic way to remove items that are 'None' from the end of a list?</p>

Is there a way to include partial using html-webpack-plugin? : <p>I am using Webpack to compile my scripts and HTML (using <code>html-webpack-plugin</code>). The thing is, I have 5 HTML files that contains the same parts and I want to move these parts to separate <code>.html</code> files and then <code>include</code> these parts in every HTML file. This way, if I will change these smaller HTML files, it will recompile every HTML file to represent these changes.</p>
<p>Webpack does this for .js files by default, but can I use something like that for HTML files?</p>

Python: How to run a select amount of code n amount of times where user input is n : newbie to python:
I'm having some trouble trying to repeat a certain part of code n times where n is user input. It would start off something like
roominput = int(input("How many rooms do you require painting?"))
The user would then input with an integer(n) and a select part of the program would repeat n amount of times, asking for the room name, room's dimensions and colour of paint for the wall. This is for a school project, so any help would be much appreciated. Thank you!

ContainsKey on treemap throws NPE : So i have a comparator that i defined for my TreeMap to sort it by values,
but when i use containsKey(anyKey) on a key that it does not contain it doesn't return false, but it throws a NullPointerException. Now what i don't understand is why it goes in my comparator for the containsKey() method and how i could find a solution... I've been stuck on this for a couple of hours and any help would be appriciated.
Here is the code :
public class test {
public static void main(String[] args) {
HashMap<Integer, Integer> map = new HashMap<>();
map.put(1,2);
map.put(2, 3);
Comparator<Integer> comp = new ValueComparator<Integer, Integer>(map);
TreeMap<Integer, Integer> tm = new TreeMap<Integer, Integer>(comp);
tm.putAll(map);
System.out.println(tm.containsKey(1)); // returns true
System.out.println(tm.containsKey(3)); //Throws NPE
}
}
class ValueComparator<K, V extends Comparable<V>> implements Comparator<K>{
HashMap<K, V> map = new HashMap<K, V>();
public ValueComparator(HashMap<K, V> map){
this.map.putAll(map);
}
@Override
public int compare(K s1, K s2) {
return map.get(s1).compareTo(map.get(s2));//descending order

Functions in Python vs Matlab : <p>I'm new to Python, coming from Matlab like many. I'm used to defining my functions as standalone .m files and calling them easily from a second script as long as the function is saved somewhere within the defined Matlab path. </p>
<p>I've learned how to define a (user-defined) function in Python (def my_function() etc.), but I'm coming up short in my Google searches on a way to define the function in a a separate .py file A, and how to call it in another script B. All help files I can find give support on how to define the function within the same script. When I try calling the function (which I've defined as a .py file in the same folder I'm using for script A) my script doesn't recognize it. Do I need to be declaring the function at the beginning of my script? I'm getting the sense that Python is very different in the way it handles these things than Matlab--perhaps I can't do this?</p>
<p>Cheers</p>

Foders and files created from external text file with same names to insert with corresponding same name.Batch :
I was inspired on works of our colleagues from portal

http://stackoverflow.com/questions/17648627/batch-script-to-read-input-text-file-and-make-text-file-for-each-line-of-input-t
to develop creation from external a text file for example "comps.txt" ( comp1,comp2.... for each PC a batch script read from a list of PCs in a text file and create a text file for each line of text as local.
Later in code are created folders files named - the same names ( comp1,comp2....
at the end we have text files : comp1.txt ,comp2.txt ... and folders: comp1 , comp2.... till 400 computers.
Any idea how to add in code or write another separate batch code to move for each coresponding folder text file for text file comp1.txt->comp1 folder ,comp2.txt->comp2.txt .... We have more than 400 lines!!
I am very begginers for any scrips working very hard every single day and this is my first question. My code in Windows Batch is below
@echo off
setlocal
for /f "tokens=*" %%a in (comps.txt) do (type nul>"%%a.txt")
for /f "tokens=*" %%a in (comps.txt) do (
echo This is line 1 of text>"%%a.txt"
)
for /f %%i in (comps.txt) do mkdir %%i
do (
echo "%%i.txt"
)
endlocal

Proper configuration for Jenkins GitHub Pull Request Builder downstream : <p>I'm trying to create two Jenkins jobs that both leverage the <a href="https://github.com/janinko/ghprb" rel="noreferrer" title="GitHub Pull Request Builder">GitHub Pull Request Builder plugin</a> in order to run multiple status checks, but I'm having trouble getting the status check from my downstream job to show up in my GitHub project.</p>
<p>Here's the summarized CI flow I'd like to setup:</p>
<ol>
<li>A pull request is opened against my git repository which triggers <strong>Upstream</strong> job to run in Jenkins</li>
<li><strong>Upstream</strong> reports its status based on the build and, if <code>SUCCESS</code>, should invoke <strong>Downstream</strong> job via a post-build action</li>
<li><strong>Downstream</strong> runs and reports its own status check</li>
</ol>
<p>Step 3 is where I'm having issues. <strong>Downstream</strong> runs properly, but it does not post a status. The status is not even available under the <strong>Branches</strong> section of my GitHub project's settings. I'm not sure how <a href="https://github.com/janinko/ghprb" rel="noreferrer" title="GitHub Pull Request Builder">GHPRB</a> does the initial creation of the status check, but there are references to the context messaging in the Console Output:</p>

Is Redundant Programming in Java Inefficient? : <p>For example I have 3 calls of one method (always 3 calls) and I need to pass 1 to method for the first call 2 for the second and 3 for the third. I can solve that Problem in 2 ways. Either make 3 calls with 1, 2, 3 or use a for loop.</p>
<pre><code>call(1);
call(2);
call(3);
for (int i = 1; i <= 3; i++) {
call(i);
}
</code></pre>
<p>The question is what will run faster. As I know this depends completly on the Java Compiler, because it could make optimizations on the for loop.</p>
<p>In plain C the redundant way would be a little bit faster I guess, because there is no counter needed to increment and compare.</p>

<p>Is there a way to limit the numbers of restarts on pm2? There is a way to restart the server when the server reaches a certain RAM memory level, so I would hope this feature I am asking for exists.</p>

Airflow tasks get stuck at "queued" status and never gets running : <p>I'm using Airflow v1.8.1 and run all components (worker, web, flower, scheduler) on kubernetes & Docker.
I use Celery Executor with Redis and my tasks are looks like:</p>
<pre><code>(start) -> (do_work_for_product1)
├ -> (do_work_for_product2)
├ -> (do_work_for_product3)
├ …
</code></pre>
<p>So the <code>start</code> task has multiple downstreams.
And I setup concurrency related configuration as below:</p>
<pre><code>parallelism = 3
dag_concurrency = 3
max_active_runs = 1
</code></pre>
<p>Then when I run this DAG manually (not sure if it never happens on a scheduled task) , some downstreams get executed, but others stuck at "queued" status.</p>
<p>If I clear the task from Admin UI, it gets executed.
There is no worker log (after processing some first downstreams, it just doesn't output any log). </p>
<p>Web server's log (not sure <code>worker exiting</code> is related)</p>
<pre><code>/usr/local/lib/python2.7/dist-packages/flask/exthook.py:71: ExtDeprecationWarning: Importing flask.ext.cache is deprecated, use flask_cache instead.

<p>There is no error log on scheduler, too. And a number of tasks get stuck is changing whenever I try this.</p>
<p>Because I also use Docker I'm wondering if this is related:

webpack dynamic module loader by require : <p>OK, i have searched high and low but cannot reliably deterrmine if this is or is not possible with webpack.</p>
<p><a href="https://github.com/webpack/webpack/tree/master/examples/require.context" rel="noreferrer">https://github.com/webpack/webpack/tree/master/examples/require.context</a>

webpack.config.js</p>
<pre><code>'use strict';
let webpack = require('webpack'),
jsonLoader = require("json-loader"),
path = require("path"),
fs = require('fs'),
nodeModules = {};
fs.readdirSync('node_modules')
.filter(function(x) {

})
.forEach(function(mod) {
nodeModules[mod] = 'commonjs ' + mod;
});
let PATHS = {
app: __dirname + '/src'
};
module.exports = {
context: PATHS.app,
entry: {
app: PATHS.app+'/server.js'
},
target: 'node',
output: {

<pre><code>let _ = require('lodash');
let modules = [ "modules/test" ];
require( 'modules/test' )();
_.map( modules, function( module ){
require( module );
});
</code></pre>
<p>The module in modules/ named test.js</p>
<pre><code>module.exports = () => {
console.log('hello world');
};
</code></pre>
<p>But the result is always the same... the pm2 logs just say hello world for the static require... but for the dynamic load of the same module</p>

<p>Error: Cannot find module "."</p>

Spring boot does not load logback-spring.xml : <p>I have a sample Spring Boot application that uses Logback for logging.
So I have <code>logback-spring.xml</code> next to the jar to configure the logging, however it does not work unless I specify it with <code>logging.config</code>, ex : <code>logging.config=logback-spring.xml</code>.</p>
<p>I have looked into <a href="https://stackoverflow.com/questions/43937031/spring-boot-ignoring-logback-spring-xml">Spring Boot ignoring logback-spring.xml</a> where it suggests that it might be because there's already a <code>spring.xml</code> somewhere, but putting breakpoint on <code>org.springframework.boot.logging.AbstractLoggingSystem.initializeWithConventions(LoggingInitializationContext, LogFile)</code> shows that logFile is empty.</p>

when to use Classes vs Objects vs Case Classes vs Traits : <p>This is what I understood so far.</p>
<p>Classes should be used when we need to instantialte objects</p>
<p>We use "Objects" only when we have a singleton requirement meaning no need for multiple instances of "objects". I am thinking when we are building common library functions or utility functions in a project, we can use "objects" that way we need to instantiate each time we use methods/functions in that Object.</p>
<p>Case classes can be used when we want to save boilerplate code. Say we have "Stock" class. Each stock in general has hundreds of member variables. Instead of developer writing code for setters and getters, if we case class, it generates lot of default code.</p>
<p>Traits: don't know when to use. Both Traits and Objects don't take parameters during initialization.</p>
<p>Any more thoughts and ideas kindly share.</p>

In Ruby, what's the advantage of #each_pair over #each when iterating through a hash? : <p>Let's say I want to access the values of a hash like this:</p>
<pre><code>munsters = {
"Herman" => { "age" => 32, "gender" => "male" },
"Lily" => { "age" => 30, "gender" => "female" },
"Grandpa" => { "age" => 402, "gender" => "male" },
"Eddie" => { "age" => 10, "gender" => "male" },
"Marilyn" => { "age" => 23, "gender" => "female"}
}
</code></pre>
<p>I could use <code>#each</code> with two parameters:</p>
<pre><code>munsters.each do |key, value|
puts "#{name} is a #{values["age"]}-year-old #{values["gender"]}."
end
</code></pre>
<p>Or I could use <code>#each_pair</code> with two parameters:</p>
<pre><code>munsters.each_pair do |key, value|
puts "#{name} is a #{values["age"]}-year-old #{values["gender"]}."
end
</code></pre>
<p>Perhaps the difference between the two is not borne out in this simple example, but can someone help me to understand the advantage of using <code>#each_pair</code> over <code>#each</code> ?</p>
