Answer 1

[WinError 2] The system cannot find the file specified: 'Screenshot (72).png

-----------> remove the space form the <file_name>.png Program :

import os
path  = os.getcwd()
filenames = os.listdir(path)
for filename in filenames:
     os.rename(os.path.join(path, filename), os.path.join(path, filename.replace(' ', '-')))
