Tell us what’s happening:
Guys I repeatedly get test_argument error when I set the second argument ‘calculation’ to True.
can anyone help me with this pls, I’m new to programming.
Your code so far
def arithmetic_arranger(problems,calculation = True):
lst =
arranged_problems = “”
if((len(problems) > 5)):
arranged_problems = “Error: Too many problems.”
else:
for i in problems:
lst.append(i.split())
if(not(i.split()[0].isnumeric()) or not(i.split()[2].isnumeric())):
return "Error: Numbers must only contain digits."
for i in lst:
if(len(i[0]) > 4):
return "Error: Numbers cannot be more than four digits."
if(not(len(i[0]) == 4)):
spc = ''
spc_up = len(i[0])
spc_down = len(i[2])
if spc_up < spc_down:
spc_len = spc_down - spc_up
else:
spc_len = 0
else:
spc_len = 0
spc = (spc_len + 2) * " "
arranged_problems += spc + i[0] + " "
arranged_problems = arranged_problems.rstrip(" ")
arranged_problems += "\n"
for i in lst:
