Tell us what’s happening:

My code won’t pass the test: number_pattern should return ’ Argument must be an integer value.’ when passed a value that is not an integer. I’ve tried a few different things, but i’m stuck on this.

def number_pattern(n):
    if n <= 0:
        return 'Argument must be an integer greater than 0.'      
    try:
        n = int(n)  # Attempt to convert to an integer
    except (ValueError, TypeError):
        return 'Argument must be an integer value.'  
    last_line = ' '.join(str(j) for j in range(1, n + 1))
    return last_line

#print(number_pattern())

It looks like you are trying to convert into an integer instead of checking if you have an integer. Which does the instructions ask for?

  1. You should define a function named number_pattern that takes a single parameter n (representing a positive integer).

  2. number_pattern should use a for loop.

  3. number_pattern(n) should return a string with all the integers starting from 1 up to n (included) separated by a space. For example, number_pattern(4) should return the string 1 2 3 4.

  4. If the argument passed to the function is not an integer value, the function should return Argument must be an integer value..

  5. If the argument passed to the function is less than 1, the function should return Argument must be an integer greater than 0..

Above are the instructions or stories. They all will pass except #4.

do the things asked in 4 and 5 in that order. Consider an input like -1.1, what do you expect the function to do?

I can read the instructions you copied and pasted, sure, but I am asking you to interpret the instructions. If you try to answer my question in your own words, that should help you see what is wrong.

If I test the code with a letter, I get a You should define a function named number_pattern that takes a single parameter n (representing a positive integer).

Thank you both for the help. I finally got it.
