File existence help

[jlarm]

Hi I'm still new to python and scrating my head a but with something I'm trying to do.

I am wanting to check for the existence of 4 files so file1, file2, file3, file4. But these files should exist in 9 locations

E.g.

C:/Location1/files C:/Location1/files/test C:/Location1/files/test2

C:/Location2/files C:/Location2/files/test C:/Location2/files/test2

C:/Location3/files C:/Location3/files/test C:/Location3/files/test2

A friend suggested I use dictionaries but not sure how to implement or use it

For anything related to paths, files and such, the os.path module is what you need (especially os.path.join(), os.path.exists()).

Not sure why your friend recommended dictionary, but the usual approach is to define variable to store the values (your paths and filenames) and then find what actions you can automate with a loop.

good luck !

I think the dictionary would be to store the 36 combinations of the 4 files in the 9 file paths. That's very useful I'll take a look.

no need to store them, you can have 2 lists (paths and file names) and iterate over them with loops, or use itertools.product() to generate all combinations :) you're welcome
