Check if Number is Between Two Numbers Using Python

In Python, you can easily check if a number is between two numbers with an if statement, and the and logical operator.

def between_two_numbers(num,a,b):
    if a < num and num < b: 
        return True
    else: 
        return False

You can also use the Python range() function to check if a number is in a range between two numbers.

def between_two_numbers(num,a,b):
    if b < a:
        a, b = b, a
    if num in range(a,b):
        return True
    else:
        return False

When working with numbers in Python, the ability to easily check for certain conditions is very valuable.

One such situation is if you want to check if a number is in a range of numbers or is between two numbers.

In Python, you can easily check if a number is between two numbers with an if statement, and the and logical operator.

All you need to do is check if a number is greater than the lower bound of the range and less than the upper bound of the range. Then, you can use and to create a multiple condition if statement.

Below is a simple function which will check if a number is between two numbers using Python.

def between_two_numbers(num,a,b):
    if a < num and num < b: 
        return True
    else: 
        return False

print(between_two_numbers(10,5,15))
print(between_two_numbers(20,5,15))

#Output:
True
False

Using range() to Check if a Number is Between Two Numbers in Python

Another way to check if a number is between two numbers in Python is to use the Python range() function and check if the number is included in a created range.

def between_two_numbers(num,a,b):
    if b < a:
        a, b = b, a
    if num in range(a,b):
        return True
    else:
        return False

print(between_two_numbers(10,5,15))
print(between_two_numbers(20,5,15))

#Output:
True
False
