**Problem**

I wrote the code and I tested on PyCharm and the outputs are the same as the required, but when I try it in repl.it all the test FAIL and I don’t know why.

**Your code so far**

def arithmetic_arranger(problems,display_answ = False):

if len(problems) > 5:

return “Error: Too many problems.”

```
problems_list = problems

display_answers = display_answ

display_answers = False

data = problem.split()
first_operand = data[0]
second_operand = data[2]
operator = data[1]
valid_operators = ('+','-')
if operator not in valid_operators:
return "Error: Operator must be '+' or '-'."
try:
first_operand = int(first_operand)
second_operand = int(second_operand)
except:
return "Error: Numbers must only contain digits."
if first_operand > 9999 or second_operand > 9999:
return "Error: Numbers cannot be digits more than four."
first_operands.append(str(first_operand))
