Are the rest of the python if statements executed if the result is already clear from the first statement?

Question

Python

I did not immediately find something in the documentation at this point
. If there is such an
if a and b and c:
where a, b, c are very very heavy functions,
will b, c be executed if a returned false?

Answer 1

It's easy to check:

>>> def return_false1():
...     print('run 1')
...     return False
...
>>> def return_false2():
...     print('run 2')
...     return False
...
>>> def return_false3():
...     print('run 3')
...     return False
...
>>>
>>> if return_false1() and return_false2() and return_false3():
...     print('I newer executed')
...
run 1

and about lazy calculations in Python have already been said above.
