How to properly overload a constructor?

Question

Python

How to override the CrawlSpider constructor so that it takes a value as input, do this:

allowed_domains = []

def __init__(self, *args, **kwargs):
        super(CrawlSpider, self).__init__(self, *args, **kwargs)
        if args == True:
            self.start_urls = ['%s' % args]
        else:
            self.start_urls = ['%s' % kwargs]

Are you asking how to write a constructor to do what it does now? Don't change anything and it will work as you ask.
But, comparing args with True is strange, they have different types and the expression will always be false. It is necessary to write like this:
I.e. use an implicit cast to a boolean variable. Compare as suggested in another comment: if args[0]most likely it is impossible. this code requires a single positional argument and checks for it.
The rest of the code is weird too. Here it is:
forms a list of one line, which will have the first positional argument. Not a list of strings, just one. And only with the first argument, but not with all.
