Python Cheat Sheet 111: Python Comparison Operators

Are you a beginner in the world of programming? Python is an excellent language to start with because of its simplicity and readability. In this tutorial, we will delve into one of the fundamental concepts of Python programming: Comparison Operators. These operators allow you to compare values and make decisions based on those comparisons. We will provide step-by-step instructions, sample Python code, and the expected output to help you grasp the concept easily.

What Are Comparison Operators?

Comparison operators are used to compare values and return a Boolean result (True or False). These operators are crucial for making decisions and controlling the flow of your Python programs. Here are the six main comparison operators in Python:

  1. == (Equal to)
  2. != (Not equal to)
  3. < (Less than)
  4. > (Greater than)
  5. <= (Less than or equal to)
  6. >= (Greater than or equal to)

Let’s dive into each of these operators with sample code and explanations.

1. == (Equal to)

The == operator is used to check if two values are equal.

# Sample Code
x = 5
y = 5
result = x == y
print(result)

Expected Output: True

Explanation: In this code, we assign the value 5 to both x and y. Then, we use the == operator to compare x and y. Since they are equal, the result is True.

2. != (Not equal to)

The != operator is used to check if two values are not equal.

# Sample Code
a = 10
b = 20
result = a != b
print(result)

Expected Output: True

Explanation: Here, a and b have different values (10 and 20, respectively). When we use the != operator, it checks if a is not equal to b, which is true in this case.

3. < (Less than)

The < operator is used to check if one value is less than another.

# Sample Code
num1 = 8
num2 = 12
result = num1 < num2
print(result)

Expected Output: True

Explanation: In this example, num1 is assigned the value 8, and num2 is assigned 12. The < operator checks if num1 is less than num2, which is true.

4. > (Greater than)

The > operator is used to check if one value is greater than another.

# Sample Code
m = 30
n = 15
result = m > n
print(result)

Expected Output: True

Explanation: Here, m is assigned 30, and n is assigned 15. The > operator compares m and n, and since m is greater, the result is True.

5. <= (Less than or equal to)

The <= operator checks if one value is less than or equal to another.

# Sample Code
value1 = 7
value2 = 7
result = value1 <= value2
print(result)

Expected Output: True

Explanation: In this code, value1 and value2 both have the value 7. The <= operator checks if value1 is less than or equal to value2, which is true.

6. >= (Greater than or equal to)

The >= operator checks if one value is greater than or equal to another.

# Sample Code
a = 25
b = 20
result = a >= b
print(result)

Expected Output: True

Explanation: Here, a is assigned 25, and b is assigned 20. The >= operator compares a and b, and since a is greater, the result is True.

Conclusion

In conclusion, mastering Python Comparison Operators is a crucial step for any aspiring programmer. These operators, including ==, !=, <, >, <=, and >=, form the foundation of decision-making in Python. Armed with a solid understanding of how they work, you’ll have the ability to write more intelligent and responsive Python code.
