Python Assignment Questions: Decision Making and Looping
========================================================

**1. Age Checker**

   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`.

**5. Sum of First N Numbers**

   Input N and print the sum of first N natural numbers using a loop.

   *Hint:* Use `for` loop with `range()`.

**6. Factorial Calculation**

   Take a number N and calculate its factorial using a loop.

   *Hint:* Use `while` loop or `for` loop, initialize result = 1.

**7. Multiplication Table**

   Input a number and print its multiplication table from 1 to 10.

   *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**

    Try to read a file and handle if it doesn't exist.

    *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`.
