Tell us what’s happening:
The code is working fine for 4 out of 6 cases, but is failing for the remaining 2 cases. The problem is that it seems to be working just fine on my PC and is returning Output as intended. I am unable to figure out what’s wrong with it.
Your code so far
def arithmetic_arranger(problems, solve = False):
# TOO Many Problems Error
if len(problems) > 5:
return "Error: Too many problems."
first = '' # The First Operand
second = ''# The Operator and the Second Operand
dash = ''# The dashline
solution = ''# The Solution
for problem in problems:
problem = problem.split() # String into List Conversion
# Check for Unsupported Operand
if problem[1] == '+' or problem[1] == '-':
pass
else:
return "Error: Operator must be '+' or '-'."
# Check for Operand Size
if len(problem[0]) > 4 or len(problem[2]) > 4:
return "Error: Numbers cannot be more than four digits."
# Everything Else
first += problem[0].rjust(len(max(problem)) + 2) + "\t"
second += problem[1] + problem[2].rjust(len(max(problem)) + 1) + "\t"
dash += '-' * (len(max(problem)) + 2) + "\t"
# The Solutions and the Last Error Check
try:
if problem[1] == "+":
add = int(problem[0]) + int(problem[2])
solution += str(add).rjust(len(max(problem)) + 2) + "\t"
else:
sub = int(problem[0]) - int(problem[2])
solution += str(sub).rjust(len(max(problem)) + 2) + "\t"
except:
return 'Error: Numbers must only contain digits.'
if solve == True:
return first + "\n" + second + "\n" + dash + "\n" + solution
else:
return first + "\n" + second + "\n" + dash + "\n"
Output:
