While Loops

Control Flow If Statements

Python’s if statements control the execution flow based on conditions.

Basic Syntax:

if condition:
    # Code to execute if condition is True
elif condition2: #Optional
    # Code to execute if condition2 is True and condition is False
else: #Optional
    # Code to execute if all above conditions are False

Example:

x = 10
if x > 5:
    print("x is greater than 5")
elif x == 5:
    print("x is equal to 5")
else:
    print("x is less than 5")

Important Notes:

• Conditions are evaluated as boolean values (True or False).
• Indentation is crucial; it defines the code blocks within each if, elif, and else branch.
• You can have multiple elif blocks.
• The else block is optional.

Comparison Operators - This should cover operators like ==, !=, >, <, >=, <=.
