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

Question

Why this function call is giving me the above error?

count=0
def returncall():
  for i,j in enumerate(range(count,count+3),0):
    print i,j
  return j
count=returncall
print count()

Answer 1

The problem is here:

for i,j in enumerate(range(count,count+3),0):

count is another name for returncall because you have done count = returncall . returncall is a function; in fact, it's the very function that statement is in. You can't add an integer to a function ( count+3 ) because that is meaningless.

I don't really understand what you're attempting to do here, so can't really offer further advice. But that's what the error message means.
