What does “TypeError 'xxx' object is not callable” means?

Question

As a starting developer in Python I\'ve seen this error message many times appearing in my console but I don\'t fully understand what does it means.

Could anyone tel

Answer 1

I came across this error message through a silly mistake. A classic example of Python giving you plenty of room to make a fool of yourself. Observe:

class DOH(object):
def __init__(self, property=None):
    self.property=property

def property():
    return property

x = DOH(1)
print(x.property())

Results

$ python3 t.py
Traceback (most recent call last):
  File "t.py", line 9, in 
    print(x.property())
TypeError: 'int' object is not callable

The problem here of course is that the function is overwritten with a property.
