Chained comparison number range in Python

Question

I have the following function:

def InRange(number):
    return 5 <= number >= 1

I want this to say false if the number is not within

Answer 1

Use this:

1 <= number <= 5

From docs:

x < y <= z is equivalent to x < y and y <= z, except that y is evaluated only once (but in both cases z is not evaluated at all when x < y is found to be false).

Your (incorrect)expression is actually equivalent to:

number >=5 and number >= 1

So, it is going to be True for any number between 1 to infinity:
