I'm trying to make a web scraper that need cookies and headers. I defined a function that returns them and I made a main function to run everything. But it doesn't get the cookies. When I run it with if __ name__ == __main: it works but if I put it in a function it doesn't.

That doesn't work:

def main(user, password):
    cookies, headers = login(user, password)
    for thread in argv[1::]:
        for photo in get_photos(thread):
            download(photo)

That does work:

if __name__ == "__main__":
    cookies, headers = login(user, password)
    for thread in argv[1::]:
        for photo in get_photos(thread):
            download(photo)

In the non-working version, did you ever actually call `main()`? – jasonharper Dec 14 '20 at 22:55
@jasonharper ofcourse I did then it gave cookie not defined error. – Enes Doğan Dec 14 '20 at 23:03
Could not find an IndentationError. – Enes Doğan Dec 14 '20 at 23:04

@EnesDoğan if you are getting that error, you need to provide a [mcve]. really, you always should provide that, otherwise, we cna only speculate, since none of this would do anything except throw an error (or simply define a function) – juanpa.arrivillaga Dec 14 '20 at 23:05
