Tell us what’s happening:

I have completed most of the code, aside from adding the answers where necessary, but no matter what I try I cannot get the equations to appear side by side, everything I try either has no effect or breaks it altogether. Please can someone point me in the right direction I’ve been struggling for hours :frowning:

Your code so far

def arithmetic_arranger(problems, show_answers=False):
     
#   creating the loop    
    for problem in problems:

#   defining the variables
        first_number = problem.split()[0]
        operator = problem.split()[1]
        second_number = problem.split()[2]
        second_row = ''
        dashes = ''
        top_row = ''
        
          
#   Running the checks
        if len(problems) > 5:
            return "Error: Too many problems."
        
        if operator == '*' or operator == '/':
            return("Error: Operator must be '+' or '-'.")
            break
        
        if not first_number.isdigit() or not second_number.isdigit():
            return('Error: Numbers must only contain digits.')
            break
        
        if len(first_number) > 4 or len(second_number) > 4:
            return('Error: Numbers cannot be more than four digits.')
            break
        
#       creating the padding
        space = max(len(first_number), len(second_number)) + 2
        top_row += first_number.rjust(space)
        second_row += operator
        second_row += second_number.rjust(space-1)
        dashes += '-' * space

#       compiling the equations
        arranged_problems = '\n'.join((top_row, second_row, dashes))

        print(arranged_problems)
            

print(f'\n{arithmetic_arranger(["32 + 698", "3801 - 2", "45 + 43", "123 + 49"])}')

To answer your question, there isn’t any specific trick for this. Assume once line is printed, it’s not possible to get back to it, and add anything. What could be done in such case to print multiple things in line?

Remember also that arithmetic_arranger is expected to return string with arranged problems.
