Mastering Decision Making in Python: A Comprehensive Guide

Decision making in Python enables you to execute different blocks of code based on specified conditions, which is essential for creating dynamic and responsive programs. This guide will explore the key concepts and types of conditional statements in Python.

Key Concepts

• Conditional Statements: Python utilizes conditional statements to perform various actions based on different conditions.
• Boolean Expression: This evaluates to either True or False, determining which block of code to execute.

Types of Conditional Statements

1. if Statement
   • Used to execute a block of code if a specified condition is true.
   • Example:
2. if...else Statement
   • Executes one block of code if the condition is true, and another block if it is false.
   • Example:
3. if...elif...else Statement
   • Allows checking multiple conditions sequentially.
   • Example:
4. Nested if Statements
   • Allows placing an if statement inside another if statement to check multiple conditions.
   • Example:

number = 10
if number > 5:
    print("Number is greater than 5")
    if number > 10:
        print("Number is also greater than 10")

number = 5
if number > 5:
    print("Number is greater than 5")
elif number == 5:
    print("Number is equal to 5")
else:
    print("Number is less than 5")

number = 3
if number > 5:
    print("Number is greater than 5")
else:
    print("Number is not greater than 5")

number = 10
if number > 5:
    print("Number is greater than 5")

Conclusion

Understanding decision making in Python is crucial for controlling the flow of your program. By effectively using conditional statements like if, else, and elif, you can make your code respond to various scenarios and inputs efficiently.
