What's the equivalent of AndAlso (&&) and OrElse (||) logical operators in Python?

In .NET VB and C#, we can use AndAlso (&&), OrElse (||) for logical operations

How about in Python, what is the equivalent logical operators? are they only limited to 'and' and 'or'?

Updated: Below is the difference between And/Or and AndAlso/OrElse
Quoted from https://stackoverflow.com/a/8409488/719998

Or/And will always evaluate both1 the expressions and then return a result. They are not short-circuiting evaulation.

OrElse/AndAlso are short-circuiting. The right expression is only evaluated if the outcome cannot be determined from the evaluation of the left expression alone. (That means: OrElse will only evaluate the right expression if the left expression is false, and AndAlso will only evaluate the right expression if the left expression is true.)

Python already does this:

def foo():
    print ("foo")
    return True

def bar():
    print ("bar")
    return False


print (foo() or bar())
print ("")
print (bar() or foo())

Returns:

foo
True

bar
foo
True

There is no need for AndAlso or OrElse in Python, it evaluates boolean conditions lazily (docs).

In python, you can use logic gates.

You can use either, for instance, and or &.
