Write a program that takes an age as input and prints “Adult” if age >= 18, otherwise “Minor”.
Hint: Use if-else statement.
2. Even or Odd
Take a number as input and print “Even” if it’s even, “Odd” if it’s odd.
Hint: Use modulo operator % with if-else.
3. Grade Calculator
Input a score (0-100) and print the grade: A (90-100), B (80-89), C (70-79), D (60-69), F (below 60).
Hint: Use if-elif-else chain.
4. Positive, Negative, or Zero
Take a number and print whether it’s positive, negative, or zero.
Hint: Use nested if statements or elif.

Hint: Use for loop with range(1, 11).
8. Count Digits
Take a number and count how many digits it has using a loop.
Hint: Use while loop dividing by 10.
9. Sum of Even Numbers
Input N and print sum of all even numbers from 1 to N.
Hint: Use for loop with if to check even.
10. Reverse a String
Take a string and print it in reverse using a loop.
Hint: Use for loop iterating backwards or build new string.
11. Prime Number Check
Take a number and check if it’s prime.
Hint: Use loop to check divisibility, use break if divisible.
12. Fibonacci Series
Input N and print first N Fibonacci numbers.
Hint: Use loop to generate sequence.
13. List Iteration with Index
Take a list of names and print each with its index.
Hint: Use enumerate() function.
14. Zip Two Lists
Take two lists of equal length and print pairs.
Hint: Use zip() function.
15. Dictionary from Two Lists
Take two lists (keys and values) and create a dictionary.
Hint: Use zip() and dict().
16. Loop with Else
Search for an item in a list and print message if not found.
Hint: Use for loop with else.
17. Break on Condition
Print numbers from 1 to 100, but stop when reaching a multiple of 7.
Hint: Use for loop with if and break.
18. Continue Example
Print numbers from 1 to 10, skipping multiples of 3.
Hint: Use for loop with if and continue.
19. Pass Statement
Create a loop that does nothing for certain conditions.
Hint: Use pass in if block.
20. List Comprehension
Create a list of squares of numbers from 1 to 10.
Hint: Use list comprehension [x**2 for x in range(1, 11)].
21. Even Numbers Comprehension
Create a list of even numbers from 1 to 20 using comprehension.
Hint: Add condition if x % 2 == 0.
22. Dictionary Comprehension
Create a dictionary with numbers as keys and their squares as values.
Hint: Use {x: x**2 for x in range(1, 6)}.
23. String Lengths
Take a list of strings and create a list of their lengths.
Hint: Use list comprehension with len().
24. Nested Loop Pattern
Print a pattern of stars using nested loops.
Hint: Use two for loops, one for rows, one for columns.
25. Matrix Operations
Take two 2x2 matrices and print their sum.
Hint: Use nested loops to iterate through elements.
26. Exception Handling Division
Take two numbers and divide them, handle division by zero.
Hint: Use try-except with ZeroDivisionError.
27. ValueError Handling
Take input and convert to int, handle invalid input.
Hint: Use try-except with ValueError.
28. File Reading with Exception

Hint: Use try-except with FileNotFoundError.
29. Multiple Exceptions
Take two numbers, divide, handle both ValueError and ZeroDivisionError.
Hint: Use multiple except blocks.
30. Finally Block
Open a file, read content, and ensure it’s closed.
Hint: Use try-except-finally.
