Conditional Statements

Conditional Statements are used in programming to make decisions based on conditions.

They help a program choose what action to perform depending on whether a condition is True or False.

Real-Life Example

• If it is raining → take an umbrella
• Else → go outside normally

Just like this, Python programs make decisions.

Example

age = 18

if age >= 18:
    print("You can vote")
else:
    print("You are too young")

Output:

You can vote

Explanation

• age >= 18 → checks condition
• if → runs when condition is True
• else → runs when condition is False

Types of Conditional Statements

• if statement – checks a condition
• if-else statement – gives two choices
• if-elif-else – checks multiple conditions
• nested if – condition inside another condition

Common Beginner Mistakes

• Missing colon (:)
• Wrong indentation
• Using = instead of ==
• Writing incorrect conditions

Why Use Conditional Statements?

• Helps in decision making in programs
• Makes apps and games smarter
• Used in login systems, grading systems, and real-life applications

Real-World Uses

• ATM machines checking balance
• Login systems verifying passwords
• Games deciding win/lose
• School grading systems

• Important for real-world programs

➤ Tips for Students

• Practice simple if conditions
• Always use colon (:) after if
• Maintain proper indentation
• Start with small programs
