Привет, я должен был добавить имя клиента в файл customer.txt
[1, “Anin Fard”, “B College”, 778]
[2, “Ali”, “C College”, 77238]
def addingcustomer(file_name,new_name):
f=open(file_name,'w')
for line in f:
if new_name==line:
return ("already existed")
elif new_name!=line:
f.write(str(new_name)+"\n")
return ("succesfully added")
выдает такую ошибку:
Traceback (most recent call last):
File "C:\Users\UserA\Desktop\Customer assignment 1\Customer assignment 2", line 77, in

File "C:\Users\UserA\Desktop\Customer assignment 1\Customer assignment 2", line 26, in function
print (addingcustomer("customerlist.txt",x))
File "C:\Users\UserA\Desktop\Customer assignment 1\Customer assignment 2", line 60, in addingcustomer
for line in f:
