"cannot unpack non-iterable method object"

Question

What is wrong with this pls help
I am trying to make a lexer but the something is wrong with the tokens variable

def make_tokens(self):
tokens = []

while self.current_char != None:
if self.current_char in ' \t':
self.advance()
elif self.current_char in DIGITS:
tokens.append(self.make_number)
self.advance()
elif self.current_char == '+':
tokens.append(Token(TT_PLUS))
self.advance()
elif self.current_char == '+':
tokens.append(Token(TT_PLUS))
self.advance()
elif self.current_char == '-':
tokens.append(Token(TT_MINUS))
self.advance()
elif self.current_char == '*':
tokens.append(Token(TT_MUL))
self.advance()
elif self.current_char == '/':
tokens.append(Token(TT_DIV))
self.advance()
elif self.current_char == '(':
tokens.append(Token(TT_LPAREN))
self.advance()
elif self.current_char == ')':
tokens.append(Token(TT_RPAREN))
self.advance()
else:
char = self.current_char
self.advance
return [], IllegalCharError("'" + char + "'")

return tokens, None

def run(text):
lexer = Lexer(text)
tokens, error = lexer.make_tokens
return tokens, error

You may have better chance for answer if you share a saved code link instead of raw text code. Less hassle for those who wants to check and debug the code, plus no risk of code truncation.
