Python case insensitive file name?

Question

I need to load a file given it's name, but the name I get is case insensitive. "A.txt" could actually be "a.txt". How to do this the fast way (not generate all possible names and try each)?

Answer 1

You could list the directory the file's in (os.listdir), and see if there are matches for your filename. The matching can be done by lower-casing both filenames and comparing.
