It puts your program in the garbage collectors hands – though the file in theory will be auto closed, it may not be closed. Python 3 and Cpython generally do a pretty good job at garbage collecting, but not always, and other variants generally suck at it.
I have this code:

Is there a Pythonic way to assign the values of a dictionary to its keys, in order to convert the dictionary entries into variables?

And this is not the only file I have to read. For the total process, I have to read 10 files. Although this will be a sequential job, I think it will a smart thing to do it without extarcting the whole information. I do not even know that it is possible. How can it be done using python? I need to read a text file line-by-line.
I tend to use only forward slashes for paths (‘/’) and python is happy with it also on windows.
In the description of os.path.join it says that is the correct way if you want to go cross-platform. But when I use it I get mixed slashes:
I have the following range of numpy data (deltas of usec timestamps):
I’m running a recent Linux system where all my locales are UTF-8:
I know this is a very basic question but for some reason I can’t find an answer. How can I get the index of certain element of a Series in python pandas? (first occurrence would suffice)
