Give me a hint please!! Not direct answer!! Why is the last loop not working? It prints zero as the total_time.

Question

class CallCenter:
def __init__(self):
self.customers = []

def is_empty(self):
return self.customers == []

def add(self, x):
self.customers.insert(0, x)

def next(self):
return self.customers.pop()

def pop(self):
return self.customers.pop()

c = CallCenter()

while True:
n = input()
if n == 'end':
break
c.add(n)

#your code goes here
general = 0
technical = 0

while n != 'end':
call = c.next()
if call == 'general':
general += 1
elif call == 'technical':
technical += 1
c.pop()

total_time = (general * 5) + (technical * 10)

print(total_time)

Neethu Nath ,

▪︎the main issue is the conditional in the while loop
▪︎if you have fixed it, a new issue may raise inside the loop like using c.pop()

in general you should think about an other way instead of using a while loop...
