Assignment 02#

Due date: 22.03.2023

This week’s assignment has to be returned in the form of two python scripts. Have a look at the instructions first!

Exercise 1#

Write a program that uses input to prompt a user for their name and preferred language, and then welcomes them.

Enter your name: Sophie
Enter your language: FR
Bonjour Sophie!

Enter your name: John
Enter your language: CN
你好 John!

The allowed languages are EN (English), DE (German), FR (French), and a fourth language of your choice. If the language is not one of these three options, the program should print an error message and exit.

Exercise 2#

Write a program that computes the probability of fog according to user input. The user first has to enter the relative humidity (a number between 0 and 100), and then, depending on the situation, the user will be asked in what season the prediction needs to be made.

The rules of fog formation are pretty simple:

  • if relative humidity is below 50%, then the probability of fog is 1%

  • if relative humidity is above or equal 50%, then the probability of fog depends on the season:

    • in summer, the probability of fog is equal to the relative humidity divided by 10

    • in winter, the probability of fog is equal to the relative humidity divided by 2

If the relative humidity is not between 0 and 100, or not a number, then the program should print a message saying that it didn’t work.

Here are a few examples of program execution:

Enter the relative humidity: 30
The probability of fog is: 1%

Enter the relative humidity: 51
What is the season? (winter or summer): winter
The probability of fog is: 26%

Enter the relative humidity: 91
What is the season? (winter or summer): summer
The probability of fog is: 9%

Enter the relative humidity: 101
The entered value is not valid.

Enter the relative humidity: ups
The entered value is not valid.

Tip: to convert your computed probability number to a string, please use the following command: str(round(number)). This command starts by rounding the number with round() then converts the output to a string with str().
