Tell us what’s happening:

Strings come out looking Identical, have run through websites to try to figure out the differences. the tests are not passing and I have no clue why. Any help would be appreaciated.

Your code so far

def arithmetic_arranger(problems, show_answers=False):
    if len(problems) > 5:
        return "Error: Too many problems."
    string1 = ""
    string2 = ""
    string3 = ""
    string4 = ""

        problemComonents = problem.split()
        if len(problemComonents[0]) > 4 or len(problemComonents[2]) > 4:
            return "Error: Numbers cannot be more than four digits."
        if problemComonents[1] != "+" and problemComonents[1] != "-":
            print(problemComonents)
            return "Error: Operator must be '+' or '-'."
        try:

print(arithmetic_arranger(["3801 - 2", "123 + 49"]))

print(str(arithmetic_arranger(["3801 - 2", "123 + 49"])) == "  3801      123\n-    2    +  49\n------    -----")

change the last lines of your code to this:

print(repr(arithmetic_arranger(["3801 - 2", "123 + 49"])))
print(repr("  3801      123\n-    2    +  49\n------    -----"))

so you will see if they are actually identical
