Pytest Results are different than my results Scientific Computing with Python Projects - Arithmetic Formatter

[lucasbalestrassi]

Greetings,

I am developing my code in my Notepad++ application since i am more used to running code there. Instead of referencing several python files like what is being done in the replit structure i simply call the function with the same arguments in my notepad++ and test to see the results in the end. Every once in a while I copy the code back into replit to see if everything is all right.

However, the results are different. For some reason the Pytest code always gets the " Too many problems" error on every single test. I tried running through the pytest files but I can’t figure out why it gets this error.

I should have a PASSED on all error conditions. I am worried i’m doing something wrong and even if I get all other conditions right I’m still going to keep getting all these wierd PyTest Errors

This is my replit code:

This is my base code on Notepad++

@lucasbalestrassi

  show_answers = False
  if problems[len(problems)-1] == True:
    show_answers = True

This is not how you set an argument with a default value

@lucasbalestrassi

problems = problems[0]

Here you are destroying the entire problems list and replacing it with the string for the first problem.

Hey @JeremyLT. Thank you very much for your input.

Indeed, i have reviewed google and fixed the default value argument.

def arithmetic_arranger(problems, show_answers = False):

About the second part of your answer. I got confused since the pytest parameters were given in double brackets ([[‘3801 - 2’, ‘123 + 49’]]). I retested the code and now it is working.

test_cases = [
    pytest.param(
        [['3801 - 2', '123 + 49']],
        '  3801      123\n'
        '-    2    +  49\n'
        '------    -----',
        'Expected different output when calling "arithmetic_arranger()" with ["3801 - 2", "123 + 49"]',

Thank you very much!
