for loop showing error(unsupported operand error) in python

Question

I am getting this error when i trying to parse through a for loop

pages=soup.find('span',{'class':'pagnDisabled'})
if pages==None:
    print 'None'
elif pages!=None:
    for i in range(2, pages + 1):
       print i

I am getting this error

TypeError: unsupported operand type(s) for +: 'Tag' and 'int'

pages isn't an int. Were you expecting an int? If so, why? — user2357112

@user2357112 the number iam getting as the value of pages is 37 — Fazeela Abu Zohra

@FazeelaAbuZohra How you can get 37, because type of pages is a Tag? — Tok Soegiharto

.find() returns a Tag object which implements a __len__ but when you try to add a Tag object with an int it will not try to use the length of the tag so you will have to explicitly call it with len(pages), which will give you back the length of a Tag's contents.

Also, .find() only returns 1 Tag. You want the .find_all() method instead.

soup.find() return a Tag. Maybe you must used soup.findall() method instead of soup.find() like this:

pages=soup.findall('span',{'class':'pagnDisabled'})
if len(pages) == 0:
    print 'None'
elif len(pages):
    for i in range(2, len(pages) + 1):
       print i
