E: Matching basic programming concepts¶

Exercise 1 (Matching basic programming concepts)

(15 min)

Match the following concepts to the following processes. In other words: Which concept is used in which process?

Sequence	What comes after what?
Selection	What is the condition? What does the condition decide?
Iteration	What is the condition? What is being iterated over?
Data	What values are being worked with?
Condition	Already part of selection and iteration.🤷

Id	Process
1	Get out of bed, put on your socks, then put on your shoes.
2	Ask a new coworker for their name and write it on a name tag.
3	Weigh yourself on the scale and tell your roommate the number.
4	Check if it is raining. If it is, output `Take an umbrella.`
5	Check if it is raining and windy. If both are true, output `Take an umbrella and a coat.` Otherwise, output `Just go.`
6	You want to cross the street. Check the traffic light. If it is red, wait. If it is green, check whether any cars are still coming; if none are coming, cross, otherwise wait a bit longer before crossing.
7	Ask a guest how many pancakes they want (`n`). Flip one pancake at a time until you’ve made that many, then serve them all together.
8	You are stirring a pot of soup. Taste it. If it isn’t salty enough, add a pinch of salt and taste again. Keep tasting and adding salt until it tastes right.
9	You want to know how many unread emails you have. Set `unread_count` to 0. As long as there is a next email in your inbox, check it; if it is unread, add 1 to `unread_count`.
10	A librarian is checking out books for a student. Ask the student how many books they want (`n`). For each of the `n` books: scan its barcode; if the book is already checked out to someone else or reserved by another student, output `Unavailable` and move to the next book. Otherwise, check whether the student has any overdue books. If they do, refuse the checkout and output `Please return your overdue books first.` Otherwise, mark the book as checked out and add 1 to a running total of books issued. After all `n` books have been processed, output the total number of books issued.

E: Conveyor belt capacity check¶

Exercise 2 (Conveyor belt capacity check)

Accept the assignment

You are going to help automation engineers in your company to determine whether a conveyor belt system can safely transport a collection of packages.

The system can be supported by any number of motors. Every motor is able to carry 12 kg of package weight (MOTOR_CAPACITY).

Prompt the user for the number of motors (motor_count) by asking:

How many motors are carrying the packages?

Then, prompt the user for the weight of packages. Assume an integer number:

How many kg of packages do we expect?

If the total package weight (total_package_weight) is less or equal than the total capacity of all motors, then print:

Yes! The conveyor belt can carry the packages.

Otherwise:

No. The conveyor belt cannot carry the packages.

Sample interactions:

How many motors are carrying the packages?
3
How many kg of packages do we expect?
10
Yes! The conveyor belt can carry the packages.

How many motors are carrying the packages?
2
How many kg of packages do we expect?
26
No. The conveyor belt cannot carry the packages.

The template assumes that you are only working with integer numbers (not decimal like 12.3).

You can use +, -, *, / symbols to perform arithmetic operations on two numbers and variables.

Draw a flowchart for this problem. Upload it as flowchart.* in your project folder.
Code your flowchart using the Code Runner on the left. It is normal that you revise your flowchart while you are coding. Store it as main.py in thesrc folder.
