🐍 Python Day 3 & Day 4: Conditional Statements (if, elif, else)
⚙️ Day 3: if and else Statements
✅ Syntax:
if condition:
# block of code
else:
# block of code
✅ Example:
age = int(input("Enter your age: "))
if age >= 18:
print("You are eligible to vote!")
else:
print("You are not eligible to vote.")
⚙️ Day 4: if, elif, and else
✅ Syntax:
if condition1:
# code block
elif condition2:
# code block
else:
# final block
✅ Example:
marks = int(input("Enter your marks: "))
if marks >= 90:
print("Grade: A")
elif marks >= 75:
print("Grade: B")
elif marks >= 60:
print("Grade: C")
else:
print("Grade: D")
💡 Important Notes:
Indentation (spaces/tabs) is mandatory in Python.
Conditions use comparison operators like ==, !=, >, <, >=, <=.
💪 Practice Exercises (Day 5 & 6):
1. Check if a number is even or odd.
2. Check if a person can vote (age ≥ 18).
3. Write a program to assign grades using if-elif-else.
4. Check if a number is positive, negative, or zero.
5. Use input() to take a number and print if it’s divisible by 3 and 5.
🔍 Output Sample:
Enter your marks: 85
Grade: B
