Learning materials

Open the assignment template in Visual Studio Code by typing lms open in the terminal. Next, install the Python Extension. You should now be able to run the provided Hello world! program by opening the file and pressing F5.

While studying the resources about Python below and in future lessons, it is a very good idea to experiment with what you're learning by writing small programs and running them. This tests your understanding of the things you're learning about, and helps you remember them.


Considering that you're a fresh student just starting out on a degree programme, there's only one possible application we could possibly have you built as your first real programming assignment. Yes, a responsible alcohol use advisor app, of course!

You'll be creating the application step-by-step, but here is a demo of how the final product should work:

Note: If you already have experience programming in another language, Python may feel weird at first. It has its own conventions, like snake_case for variables and functions (instead of camelCase or TitleCase), not using (braces) around if conditions, and not using semicolons; after each statement. As a multi-lingual programmer, you should get used to learning and sticking to the conventions of the programming environment you're currently working in.

Objective #1: Welcome!1.2 points

All great things start with a small first step.

Within the file, create a program that just prints the following output:

*** Responsible alcohol use calculator ***

Notice the empty lines before and after the title.

Hint: You'll require the use of print and a "string". Note that strings can be empty: "".

Objective #2: Who's this?1.2 points

Extend your program to ask the user's name, and to say hi to her or him. The output should look something like this:

*** Responsible alcohol use calculator ***

What's you name? Frank
Hi Frank

When the user enters a name different than Frank that name should of course be used to say hi to.

Hint: You'll require the use of input and a variable. Make sure to give your variable a fitting name. Remember that print can have multiple arguments, separated by commas, to output multiple things on one line.

Objective #3: Gender?1.2 points

Extend your program to ask the user's gender. Print a womanly message when the user enters 'female' and print a manly message when the user enters 'male'. For now, don't do anything when the user enters something else.

Hint: You'll require the use of if and the == operator (for comparison).

Objective #4: Drinks?1.2 points

Have your program ask for the weekly number of alcoholic beverages the user drinks on average. Then show how many beverage that are per year.

*** Responsible alcohol use calculator ***

What's you name? Frank
Hi Frank!
What's your gender? [female/male] male
Men are awesome!
How many alcoholic beverage do you drink on average per week? 10
That's 520 per year!

For now, your application may just crash (quit with an error message) when the user enters anything other than a whole number.

Hint: You'll require int to convert a string to an integer, in order to do the * calculation.

Objective #5: A word of advice1.2 points

  • When the user drinks 0 alcoholic beverages per week, output the text Healthy choice, <NAME>!.
  • Otherwise, if the user drinks less than 7 alcoholic beverages per week, output the text You'll probably be okay, <NAME>!.
  • Otherwise output the text Drinking less would be a healthier choice, <NAME>!.

Hint: You'll require the use of elif and else.

Objective #6: Gender-specific advice1.2 points

Instead of just saying Drinking less would be a healthier choice, we want to add some more stringent advice, but the norms are based on the gender of the drinker.

  • For women, the norm for excessive drinking is 14 beverages per week.
  • For men, it's 21 beverages per week.

Based on that:

  • When the user doesn't drink more than the norm, we'll stick to the messages from the previous assignment: Drinking less would be a healthier choice.
  • Otherwise, when the user doesn't drink more than twice the norm, we want to output You're an excessive drinker, <NAME>. That's not healthy..
  • If the user drinks even more, we want to output You're a really heavy drinker, <NAME>. That's very unhealthy. Change your ways!

Hint: Write the norm for the selected gender to a (fittingly named) variable, assigning it the appropriate value in the if-block for gender. Next, you can use that variable to extend the if/elif/else construct from the previous objective.

Objective #7: Error handling1.2 points

Users rarely behave the way we programmers think they should. They've been know to type the biggest nonsense into your carefully crafted application! It's up to us programmers to deal with all of that.

In each of these cases, the program should display a respectful error message and then stop the program:

  • When the user leaves the name field empty.
  • When the user enters a gender other than male or female.
  • When the user enters a beverage count that is not a whole number (integer).

After doing this, your program should be unbreakable (semi-Dutch: hufterproof).


  • You can call the exit() function to stop your Python program early (before it reaches the end).
  • For the last check, you can use try and except to catch the error thrown by the int function when you pass it a string that does not contain a proper integer number. Try to keep the code block you surround with try and except as small as possible.

Objective #8: PunctualityMUST

Attention to detail is very important in your way to become an awesome developer. Make sure that the output of your program:

  • Closely matches the provided video and example outputs.
  • Contains no spelling errors. Hint: Install the Code Spell Checker extension (by streetsidesoftware) for Visual Studio Code. Just take a minute to do this. Really.
  • Uses correct and easy to understand messages.
  • Uses capital letters, white spaces and punctuation in all the right places.

Objective #9: Code quality+ 0.4 points- 1.4 points

Your code should be easy to understand, using the simplest possible logic, sensible variable names, empty lines to separate distinct parts of the program and consistent use of whitespace.
