Question

For instance, these are defined in the operator module and can be used as such:

import operator
print operator.__add__   # alias add -> +
print operator.__sub__   # alias sub -> -
print operator.__and__   # alias and_ -> &
print operator.__or__    # alias or_ -> |

Then what is the equivalent of and and or?

print operator."and ?????"  # should be boolean-and
print operator."or ????"    # should be boolean-or

Answer 1

These do not exist. The best you can do is to replace them with a lambda:

band = (lambda x,y: x and y)
bor = (lambda x,y: x or y)

The reason is you can not implement the complete behavior of and or or because they can short circuit.

E.G:

if variable or long_fonction_to_execute():
    # do stuff

If variable is True, the long_fonction_to_execute will never be called because Python knows than or has to return True anyway. It’s an optimization. It’s a very desirable feature most of the time, as it can save a lot of useless processing.

But it means you cannot make it a function:

E.G:

if bor(variable, long_fonction_to_execute()):
    # do stuff

In that case, long_fonction_to_execute is called even before being evaluated.

Luckily, you rarely need something like that given the fact that you an use generators and list comprehensions.
