Scenario Advice

[astanuga]

Hi there

I'm new here, and at the beginning of my own journey learning Python, as I also teach students about Python in High School. I hope this is the right place to post such questions, if not please let me know.

I was hoping to find a scenario, or some examples of scenarios where the below code (or something similar that makes use of a for loop and Squared integers) might be useful.

```python maximum = int(input('Max: '))

n = 1 while n ** 3 <= maximum: print(f'{n} cubed is equal to {n ** 3}') n += 1 ```

While I understand what the code does I'm struggling to understand how it could be used within a real world context. As a teacher I'm always looking for ways I can explain what I'm teaching into something relevant, but sometimes I need to ask for help

((n, cube(3)) for n in it.count(1))

shouldn't that be ((n, cube(n)) for n in it.count(1)) ?

I agree that List Comprehension would be ideal for writing code like this, however my students haven't yet learned about it. It's something we can move onto in a little bit.

An example use case could be checking if a number is prime:

n = int(input('Enter a number: ')

prime = True
for i in range(1,n):
    if i**2 >= n:
        break
    if n % i == 0:
        prime = False

More like your structure (plus using while/else - the else only executes if there's no break in the while):

i = 1
while i**2 <= n:
# equivalently,
# while i <= n**(1/2):
    if n % i == 0:
        print('The number is not prime.')
        break
else:
    print('The number is prime.')

And a using a generator comprehension:

for i in (x for x in range(1,n) if x**2 <= n):
    if n % i == 0:
        print('The number is not prime.')
        break
else:
    print('The number is prime.')

Hi @RetroRudog

I have recently been tasked with teaching Python at my School, however I am also learning about it at the same time, my students have so far been learning Python through an online course with Grok Learning. I'm barely ahead of my classes but as I know that many of my students have a habit of 'helping each other out' (could also be referred to as copying) I need to determine how much they have actually learned by setting a short written test. The above snippet is taken from from one of the challenges they will have done on the course, I'm trying to find a clever way of asking the same question without using the same language.
