Python script to find extensions in directory

Here is a way to find out what type of windows extensions.  pictures in this case.

Count how many of each.

 

import os

ext_count = dict()
my_root = r"C:\Users\jonallen\Pictures"  # some dir to start in

for root, dirs, files in os.walk(my_root):
    for file in files:
        pathname, exten = os.path.splitext(file)
        if exten in ext_count.keys():
            ext_count[exten] += 1
        else:
            ext_count[exten] = 1
        
print(extensions)

for k in ext_count.keys():
    print(" ext:  ", k, "has ", ext_count[k], " occurances")
