**Tell us what’s happening:**

Describe your issue in detail here.

My code outputs the way it was asked to on my machine. But when running on the replit website, it doesn’t pass the tests… Why is that?

and i cant run the code with the run button

**Your code so far**

```
import re
numb1 = []
numb2 = []
opp = []
res = []
def verification(list):
if len(list) > 5:
print("Error: Too many problems.")
for i in list:
if re.search("[A-Za-z]", i):
print("Error: Numbers must only contain digits.")
if re.search(r".*\s[/*]\s.*$", i):
print("Error: Operator must be '+' or '-'.")
numb = i.split(" ")
if len(numb[0]) > 4 or len(numb[2]) > 4:
print("Error: Numbers cannot be more than four digits.")
else:
numb1.append(numb[0])
opp.append(numb[1])
numb2.append(numb[2])
if numb[1] == "+":
res.append(str(int(numb[0]) + int(numb[2])))
elif numb[1] == "-":
res.append(str(int(numb[0]) - int(numb[2])))
def show(result):
