How to create a python program to capture data to a file?

We are prohibited on EE to do someone's homework, but can give pointers.

For ex, one way to write in a file in Python is:

f = open('myfile','w')
f.write('hello world\n') # \n is a line break
f.close()

Select allOpen in new window

Yes. Python allows to save data structures to file and restore them. The process is called serialization. See pickle module for details.

@techtonik: Actually, saving a data and saving the data structures are two slightly different things. The serialization is for the second purpose. More often, it is used for passing the parts of the data structures throught network or for storing the state of the program say during hibernation.

@pepr: I don't see how it contradicts with the question. Operating with data in structured manner is more convenient than manually converting everything to strings. There is no requirement to save user input into human readable format, so for this question saving data and saving structured data is the same.

So the solution was that pickle is hard. Could not have guessed from the OP :)

Well, the question tag even says "Python list", which makes sense in the context.

@Dan: pickle is possibly a bit sour to be swallowed by beginners to get that "Aha!" kind of understanding :)
