Tell us what’s happening:
so i think getting error because of formatting of the answer
Your code so far
import re
def arithmetic_arranger(problems, *args):
if len(problems) > 5:
return "Error: Too many problems."
num1_arr =[]
num2_arr =[]
dashes_arr =[]
ans_arr = []
for equation in problems:
equation = equation.split(" ")
num1 = equation[0]
sign = equation[1]
num2 = equation[2]
regex = "\D"
reg_sign = re.search("[+-]", sign)
if reg_sign:
if re.search(regex, num1) or re.search(regex, num2):
return "Error: Numbers must only contain digits."
if len(num1) > 4 or len(num2) > 4:
return "Error: Numbers cannot be more than four digits."
biggest_num = max(len(num1), len(num2))
spaces = biggest_num + 2
dashes = "-"*(spaces)
answer = eval(f"{num1} {sign} {num2}")
num1_arr.append(f"{int(num1):>{spaces}}")
num2_arr.append(f"{sign}{int(num2):>{spaces-1}}")
dashes_arr.append(dashes)
ans_arr.append(f"{answer:>{spaces}}")
else:
return "Error: Operator must be '+' or '-'."
arranged_problems = [" ".join(num1_arr).rstrip()," ".join(num2_arr).rstrip()," ".join(dashes_arr).rstrip()," ".join(ans_arr).rstrip()]
arranged_problems2 = "\n".join(arranged_problems)
#print( arranged_problems2)
return arranged_problems2
the output
F..F..
