How to construct a set out of list items in python?

Question

I have a list of filenames in python and I would want to construct a set out of all the filenames.

filelist=[]
for filename in file         


        

Answer 1

The most direct solution is this:

s = set(filelist)

The issue in your original code is that the values weren't being assigned to the set. Here's the fixed-up version of your code:

s = set()
for filename in filelist:
    s.add(filename)
print(s)
