Hi everyone. I’m pretty new with python and I’m having trouble with the exit format of the arithmetic problems (as many do). I compared the format with the tests, they look exactly the same, yet I cannot pass the tests =(
Let me share the code of the function (It is also in a link at the end of this message). Please I would appreciate if someone could tell me why I’m getting wrong results. Thanks!
def arithmetic_arranger(problems, show_result=False): if len(problems)>5: print('Error: Too many problems.') quit() first= sign=  second=  spaces= #List that saves the maximum spaces for each operation diff_spaces= #list used to accomodate lines 1 and 2 in the exit result=[ ] counter=0 for elem in problems: x=elem.split() # Convert the elements to int to make math operations try: first_int= int(x) sec_int= int(x) except: print('Error: Numbers must only contain digits.') quit() if len(x)>4 or len(x)>4: print('Error: Numbers cannot be more than four digits.') quit() #The first and second elements as well as the sign go in different lists first.append(x) sign.append(x) second.append(x) #Tracking the operand with the higher length, to order the output if len(x)>=len(x): length= len(x) else: length= len(x) spaces.append(length) difference= len(x)-len(x) diff_spaces.append(difference) #Math operations and checking for error in the sign if sign[counter]=='+': result.append(str(first_int+sec_int)) elif sign[counter]=='-': result.append(str(first_int-sec_int)) else: print('Error: Operator must be ''+'' or ''-'' ') quit() counter=counter+1
