Python script to ensure Windows PATH has distinct values

ospath-win.py

# Not sure why some of them appear repeated but sometimes they do.
# Since there is a limit of 1024 chars to the SETX command, this sometimes comes in handy.
import os
path = os.environ['PATH']
elements = path.split(';')
elements = set(elements)
new_path = ''
for item in elements:
    new_path+='{};'.format(item)

with open('newpath.txt', 'w') as output:
    output.write(new_path)
