Comparison Operators in Python

Operators are symbols that are used to perform operation on variables and values. In this article we will discuss comparison operators in Python.

In this article, we are going to talk about yet another type of operator in Python – the Comparison operator. We’ll learn how the comparison operators perform operations in Python through examples. We have also discussed the following Python operators in previous articles:

• Arithmetic Operators in Python
• Bitwise Operators in Python
• Ternary Operators in Python
• Assignment Operators in Python

We will be covering the following sections today:

• What are Comparison Operators?
• Types of Comparison Operators in Python

What are Comparison Operators?

Comparison operators in Python, also called relational operators, are used to compare two operands. They return a Boolean True or False depending on whether the comparison condition is true or false.

The following table describes the different comparison operators in Python with their names, descriptions, and syntax –

Operator	Name	Syntax
<	Less than	a < b
>	Greater than	a > b
<=	Less than or equal to	a <= b
>=	Greater than or equal to	a >= b
==	Equal to	a = (b+c)
!=	Not equal to	a != b

Types of Comparison Operators in Python

Below, we are going to look at the Python implementation of each comparison operator one by one:

Less than

This operator is simply denoted by the “<“ sign. Returns True if the left operand is less than the right operand.

Output

True

Because 3 is less than 7. Hence, the expression is true.

Output

False

Because 3 cannot be less than itself. Hence, the expression is false.

Output

True

In this case, the result is true because the ASCII code for ‘S’ is 83 which is less than the ASCII code for ‘s’ which is 115. Rest of the characters are same hence only this makes a difference.

Output

True

Output

False

NOTE: We can compare tuples having only the same type of data.

Greater than

This operator is simply denoted by the “>” sign. Returns True if the left operand is greater than the right operand.

Output

True

Output

False

Output

(3, 4, True, 4, 5.0)

In this case, (5 > 3) is considered an expression and since this is true, we get the above output.

Output

True

Boolean False stands for 0. So, 0.5 > 0. Hence, the output is true.

Less than or equal to

This operator is simply denoted by the “<=” sign. Returns True if the left operand is either less than or equal to the right operand.

Output

True

Output

False

Greater than or equal to

This operator is simply denoted by the “>=” sign. Returns True if the left operand is either greater than or equal to the right operand.

Output

Output

False

Equal to

This operator is simply denoted by the “==” sign. Returns True if the left operand is exactly equal to the right operand.

Output

Output

False

Output

True

Output

True

Not equal to

This operator is simply denoted by the “!=” sign. Returns True if the left operand is not equal to the right operand.

Output

Output

False
