python: function takes exactly 1 argument (2 given)

Question

I have this method in a class

class CatList:

    lista = codecs.open(\'googlecat.txt\', \'r\', encoding=\'utf-8\').read()
    soup = BeautifulSoup(lista)            


        

Answer 1

You forgot the self argument.

You need to change this line:

def parseList(tag):

with:

def parseList(self, tag):

You also got a global name error, since you're trying to access parseList without self.
While you should to do something like:

self.parseList(item)

inside your method.

To be specific, you need to do that in two lines of your code:

 return [self.parseList(item)

and

 return (tag.contents[0].string.strip(), self.parseList(tag.ul))
