Conditional Statements and Error Handling in Python

Please save your solutions for Exercises 1 to 6 in a single Python script named unit04__ex(1-6)code.py.
For Bonus Exercise 8, use a separate Python script named unit04__ex7code.py.

Save all scripts in the same unit04 folder, compress the folder into a .zip file, and upload it to ILIAS.

For more information, please visit the following link:

Make sure your code is clearly structured and includes comments where helpful.

Exercise 1 – Theory Test (Multiple Choice)

Which of the following statements are correct?

A) An if statement can never be used without else.
B) elif can only be used once per if block.
C) try-except only catches import errors.
D) if, elif, else allow checking different conditions in sequence.
E) try-catch is the correct syntax for error handling in Python.

Select all correct answers.

Exercise 2 – Temperature Check (if)

Write a program that asks the user to enter a temperature in °C.
If the temperature is below 0, print:
"Warning: Risk of frost!"

Example:

Temperature: -3
Warning: Risk of frost!

Exercise 3 – Age Check (if-else)

Ask the user for their age.
If the age is at least 18, print: "Access granted."
Otherwise, print: "Access for adults only!"

Exercise 4 – Weekday Checker (if-elif-else)

Ask the user to enter the name of a weekday ("Monday" to "Sunday").
Print whether it’s the start of the week, midweek, or weekend.

Example:

Day: Monday
It is the start of the week.

Exercise 5 – Password Strength (nested ifs)

Ask the user to enter a password. Depending on the length, print:

  • Length < 4 → "Way too short!"
  • Length < 8 → "Too short"
  • Length ≥ 8 → "Strong password"

Hint: Use nested if statements.

Exercise 6 – Grade Evaluation (if-elif-else)

Ask the user for a score (0–100) and print a grade:

  • 90–100 → "Very good"
  • 75–89 → "Good"
  • 60–74 → "Satisfactory"
  • 50–59 → "Sufficient"
  • <50 → "Failed"

Exercise 7 – Bonus: Mini Calculator with Error Handling (try-except)

Create a program that asks the user to input two numbers and divides them.
Use try-except to catch division by zero.

Example:

Number 1: 10
Number 2: 0
Error: Division by zero is not allowed!
