python logical operator with variable number of arguments

Question

is there a way in python to check the logical operator AND with variable number of arguments. for example:

def and_function(a,b,c,d,e....):
    if a and b and c and d and c and d and e and . and . is True:
        return True

i see that this is possible using *args function and using a counter. But wish to know if there is a better way of doing it.

Such `and_function` exists already: [`all()`](https://docs.python.org/3/library/functions.html#all). — Ilja Everilä, Jan 05 '18 at 11:28

You basically want all() but to customize it you can use this:

def and_function(*args):
    return all([a > 5 for a in args])

Note that in case of `any()` and `all()` it's better not to first generate a list and then pass that as the iterable, because both can short circuit if given a generator, but your list has to be generated fully. – Ilja Everilä Jan 05 '18 at 11:42
