Closing file opened by ConfigParser

Question

I have the following:

config = ConfigParser()
config.read(\'connections.cfg\')
sections = config.sections()

How can I close the file opened

Answer 1

The difference between ConfigParser and RawConfigParser is that ConfigParser will attempt to "magically" expand references to other config variables, like so:

x = 9000 %(y)s
y = spoons

In this case, x will be 9000 spoons, and y will just be spoons. If you need this expansion feature, the docs recommend that you instead use SafeConfigParser. I don't know what exatly the difference between the two is. If you don't need the expansion (you probably don't) just need RawConfigParser.
