Double Comparisons in Python

In Python, you can use double comparisons, where you write comparison operators on the left and right sides of a variable.

Let us have a variable tst:

tst = 3

Let's do a double comparison for her:

if 2 < tst < 10:
	print('+++')
else:
	print('---')

Given a variable:

tst = 15

Check that it is greater than 10 and less than 20.

Given a variable:

tst = -5

Check that it is less than 0 and greater than -10 or greater than -8 and less than 30.

Given a list:

tst = ['a', 'b', 'c', 'd', 'e']

Check that its length is less than 6 and greater than 0.
