'int' object is not callable in python

Question

I got this and I was expecting it to print 410 when I print x.withdraw().

You set an attribute on the instance with the same name:

self.withdraw = withdraw

It is that attribute you are trying to call now, not the method. Python doesn't differentiate between methods and attributes, they do not live in separate namespaces.

Use a different name for the attribute; withdrawn (past tense of to withdraw) springs to mind as a better attribute name:

class Bank:
    def __init__(self, name, id, balance, withdrawn):
        self.name = name
        self.id = id
        self.balance = balance
        self.withdrawn = withdrawn
    def print_info(self):
        return "%s %d %d" % (self.name, self.id, self.balance)
    def withdraw(self):
        if self.withdrawn > self.balance:
            return "ERROR: Not enough funds for this transfer"
        elif self.withdrawn < self.balance and self.withdrawn >= 0:
            self.balance = self.balance - self.withdrawn
            return self.balance
        else:
            return "Not a legitimate amount of funds"

(I also corrected a typo; you used balace in one location where you meant to use balance).
