Introduction to Python comparison operators
In programming, you often want to compare a value with another value. To do that, you use comparison operators.
Python has six comparison operators, which are as follows:
- Less than ( < )Less than or equal to (<=)Greater
than (>)Greater than or equal to (>=)Equal to ( == )Not equal to ( != )
These comparison operators compare two values and return a boolean value, either True or False.
And you can use these comparison operators to compare both numbers and strings.
Less than operator (<)
The Less Than operator (<) compares two values and returns True if the value on the left is less than the value on the right. Otherwise, it returns False:
left_value < right_value
Code language: Python (python)The following example uses the Less Than (<) operator to compare two numbers:
>>> 10 < 20 True >>> 30 < 20 False
Code language: Python (python)It’s quite obvious when you use the less-than operator with the numbers.
The following example uses the less than operator (<) to compare two strings:
>>> 'apple' < 'orange' True >>> 'banana' < 'apple' False
Code language: Python (python)The expression 'apple' < 'orange' returns True because the letter a in apple is before the letter o in orange.
Similarly, the 'banana' < 'apple' returns False because the letter 'b' is after the letter 'a'.
The following example shows how to use the less-than operator with variables:
>>> x = 10 >>> y = 20 >>> x < y True >>> y < x False
Code language: Python (python)Less than or equal to operator (<=)
The less than or equal to operator compares two values and returns True if the left value is less than or equal to the right value. Otherwise, it returns False:
left_value <= right_value
Code language: Python (python)The following example shows how to use the less than or equal to operator to compare two numbers:
>>> 20 <= 20 True >>> 10 <= 20 True >>> 30 <= 30 True
Code language: Python (python)And this example shows how to use the less than or equal to operator to compare the values of two variables:
>>> x = 10 >>> y = 20 >>> x <= y True >>> y <= x False
Code language: Python (python)Greater than operator (>)
The greater than operator (>) compares two values and returns True if the left value is greater than the right value. Otherwise, it returns False:
left_value > right_value
Code language: Python (python)This example uses the greater than operator (>) to compare two numbers:
>>> 20 > 10 True >>> 20 > 20 False >>> 10 > 20 False
Code language: Python (python)And the following example uses the greater than operator (>) to compare two strings:
>>> 'apple' > 'orange' False >>> 'orange' > 'apple' True
Code language: Python (python)Greater Than or Equal To operator (>=)
The greater than or equal to operator (>=) compares two values and returns True if the left value is greater than or equal to the right value. Otherwise, it returns False:
left_value >= right_value
Code language: Python (python)The following example uses the greater than or equal to operator to compare two numbers:
>>> 20 >= 10 True >>> 20 >= 20 True >>> 10 >= 20 False
Code language: Python (python)And the following example uses the greater than or equal to operator to compare two strings:
>>> 'apple' >= 'apple' True >>> 'apple' >= 'orange' False >>> 'orange' >= 'apple' True
Code language: Python (python)Equal To operator (==)
The equal to operator (==) compares two values and returns True if the left value is equal to the right value. Otherwise, it returns False :
left_value == right_value
Code language: Python (python)The following example uses the equal to operator (==) to compare two numbers:
>>> 20 == 10 False >>> 20 == 20 True
Code language: Python (python)And the following example uses the equal to operator (==) to compare two strings:
>>> 'apple' == 'apple' True >>> 'apple' == 'orange' False
Code language: Python (python)Not Equal To operator (!=)
The not equal to operator (!=) compares two values and returns True if the left value isn’t equal to the right value. Otherwise, it returns False.
left_value != right_value
Code language: Python (python)For example, the following uses the not equal to operator to compare two numbers:
>>> 20 != 20 False >>> 20 != 10 True
Code language: Python (python)And the following example uses the not equal to operator to compare two strings:
>>> 'apple' != 'apple' False >>> 'apple' != 'orange' True
Code language: Python (python)Summary
- A comparison operator compares two values and returns a boolean value, either True or False.Python has six comparison operators: less than (<), less than or equal to (<=), greater than (>), greater than or equal to (>=), equal to (==), and not equal to (!=).
