Yes, the L signifies a long (which is practically only limited by the memory and computation time). Python in general does automatic promotions of ints to longs as soon as the value exceeds the range the int type can handle. Also, if some operation with another long takes place, the result always is a long (0 + 0L → 0...

Instead of clicking in "Python Run", you may press Ctrl+Alt+Enter with the desired Python file active, and the console will call execfile on it. All your previous story stays there. You can also select some part of your code and run only it. As far as I know, you can't. Check the pdb module instead.

I've just started using pydev in Eclipse and I have a lot of questions about the way the interactive console works. I have found out how to launch an interactive console and use it to run functions. My questions are this: Every time I change my code and re-run it, my interactive console disappears. This is annoying as...

Have you considered giving the interpreter location as a relative path? For example: ..\..\..\python\python.exe. I am not sure what the working directory of PyDev is, but if you put enough .. in, Windows will stop at the drive root.

I would look into IronPython on your Windows client side. Simply because this will give you access to COM+ DLLs and other WinAPI objects. It's .NET, but it would still be python. I've not used it enough to say for 100% certainty it will work with VSS, but it should.

When you send the login information (and usually in response to many other requests) the server will set some cookies to the client, you must keep track of them and send them back to the server for each subsequent request. A full implementation would also keep track of the time they are supposed to be stored.

if you're using the edgeNGram tokenizer, then it will treat "EdgeNGram 12323" as a single token and then apply the edgeNGram'ing process on it.

My first thought is that you could use a service oriented architecture to separate these tasks. Each of these services could run a Flask app on a separate port (or machine (or pool of machines)) and communicate to each other using simple HTTP.

Your best option is probably to find a [dynamic DNS] provider. The idea is to have a client running on your machine which updates a DNS entry on a remote server. Then you can use the hostname provided instead of your IP address in cPanel.

Using continue in Python, personally, is fine. If you're putting it in a if/else statement type condition in python, continue will work.

Is using continue in Python considered bad practice? It seems like stopping a function/etc mid-execution is a generally "poor" way to construct a program, like sys.exit() under the wrong circumstances, or goto.
Is "continue" bad practice?

The basis of structured programming is to have well defined entry and exit points into a method - ideally one of each. However, this isn't a hard and fast rule, and there are many cases where it is appropriate to have multiple exit points. I would say have a look at the code, think about whether there's a different way...

Use of flow control is a controversial subject. One school of thought believes that they obscure the code, by hiding the flow control a reader would assume -- a linear one. Another school of thought thinks that they are justifiable if the alternative is complicated logic (like additional flags and more complex loop c...

I ended up using BaseManager.start() to spawn a new process for the manager. I also used a customized proxy by subclassing BaseProxy and registered the proxy with the manager. I still don't know how to create a pipe into the spawned process, but that wasn't the main problem anyways.

So I have this object that is available in a different process. How can I expose this object using an alias in my current process so that whenever I call a method on the alias (proxy), it will be pickled and called on the referent object and raise any exceptions if there is. I also like the data to be sent over a pipe...

The functionality doesn't exist currently. We ended up having to extend pyOpenSSL to handle this.

I'm trying to get the dates for a CRL using PyOpenSSL. The CRL class doesn't contain them as accessible members. I'm going through all of the underscore members, but I'd rather not use one of those, as they're not supposed to be 'public'. Any suggestions on getting the dates out?

If you already know the salesforce Id of the record, just call update instead.

I'm using beatbox API to update/insert data in to salesforce opportunity object. upsert() throws INVALID FIELD error when I pass Id as externalIDFieldName. Currently I'm using another unique external Id and it's working fine but I want to use the salesforce Id. Please shed some light on what I'm missing.

If you're dealing with currency and accuracy matters, don't use float, use decimal.

I have a list and it contains a certain number '5.74536541' in it which I convert to a float. I am printing it out in Python 3 using ("%0.2f" % (variable)) but it always prints out 5.75 instead of 5.74. I know you're thinking who cares, but it is for a currency converter program and I don't want the currencies to rou...

If the number is a string then truncate the string to only 2 characters after the decimal and then convert it to a float. Otherwise multiply it with 10^n where n is the number of digits after the decimal and then divide your float by 10^n.

It is possible to create multiple virtualenvs with the same name; they must be in different parent directories, however. Alternately, you could create multiple virtualenvs in the same parent directory, but with different names.

I see two ways of getting this, both of which look like a detour – which makes me think there must be a better way which I'm overlooking. Converting the MultiIndex into columns: df[df.reset_index()["B"] == 2] Swapping the name I want to use to the start of the MultiIndex and then use lookup by index: df.swaplevel(0, "...

When I have a pandas.DataFrame df with columns ["A", "B", "C", "D"], I can filter it using constructions like df[df["B"] == 2]. How do I do the equivalent of df[df["B"] == 2], if B is the name of a level in a MultiIndex instead? (For example, obtained by df.groupby(["A", "B"]).mean() or df.setindex(["A", "B"]))
boolean indexing on index (instead of dataframe)

I would suggest either: df.xs(2, level='B') or df[df.index.get_level_values('B') == val] I'd like to make the syntax for the latter operation a little nicer.
