True, but even in C you can have pointers to functions
which work in a similar fashion.

Apart from C-like languages like C++, Objective C, C# and others with
objects :-)

But it is like *other* certain other languages.
:-)
Python's execution model is different from C, Pascal or Fortran, but it
is quite similar to Ruby, Lua and Javascript.

Another thought comes to mind...

You *always* CALL a method (or function) with parentheses.
But sometimes you can grab hold of a method (or

You call anything in Python (function, method, class, etc) using
parentheses. The parentheses are what makes it a call.
When you don't use parentheses you are referencing the
callable
Dear Python experts,

It seems inconsistent.
For example,
If I do
