Conditional Statements in Python

Conditional statements allow Python programs to execute code based on conditions.

1. `if` Statement

Executes a block of code if a condition is True.

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

2. `if...else` Statement

Executes one block if condition is True, another if False.

age = 18
if age >= 18:
    print("You are an adult")
else:
    print("You are a minor")

3. `if...elif...else` Statement

Handles multiple conditions.

marks = 85

if marks >= 90:
    print("Grade: A")
elif marks >= 75:
    print("Grade: B")
elif marks >= 60:
    print("Grade: C")
else:
    print("Grade: D")

4. Nested `if` Statements

Place if statements inside another if for complex conditions.

num = 10

if num > 0:
    print("Positive number")
    if num % 2 == 0:
        print("Even number")
    else:
        print("Odd number")

5. Conditional Expressions (Ternary Operator)

Short form of if-else in a single line.

age = 20
status = "Adult" if age >= 18 else "Minor"
print(status)

6. Key Points

if executes code when condition is True.
elif checks additional conditions.
else runs when all conditions are False.
Supports nested conditions and ternary expressions.
Conditions use comparison operators (==, !=, >, <, >=, <=) and logical operators (and, or, not).
