Python documentation says:
> exception TypeError
>
> Raised when an operation or function is applied to an object of
> inappropriate type. The associated value is a string giving details
> about the type mismatch.
For example:
>>> 'foo' + (1, 2)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: cannot concatenate 'str' and 'tuple' objects
So far so good. But why the following code gives a TypeError too?
>>> class C(object):
... def __init__(self):
... pass
...
>>> C(1)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: __init__() takes exactly 1 argument (2 given)
I'm having hard times understanding why a TypeError is raised here.
Could you explain?
Thanks.
