Can someone tell me what's wrong with my code?? I'm trying the military time problem in the code coach. But i only get 2/5

Question

time = input()
meridian = ''.join(time[5:])

if 'AM' in time:
print(''.join(time[0:5]))

else:
mil_time = int(''.join(time[0:2]))
mil_time += 12
mil_time = str(mil_time)

time = list(time)
mil_time = list(mil_time)

for i in range(2):
time[i] = mil_time[i]

print(''. join(time[0:5]))

Answer 1

Input => 22:00 AM
✅ expected output => 00:00
❌ But your code outputs => 12:00

Answer 2

There are two bugs in your code
1) Output Format is given in the problem statement to be:
A string that includes the time in a 24 hour format (XX:XX)
But when
1:00 AM is given as an input then output of the code is 1:00 but the expected output is 01:00

2) the input in PM gives error

Answer 3

Arsenic Smiley thanks guys for the help. I've rectified those issues that you raised but the hidden test case 4 keeps raising an error. Below is the corrected code:

time = input()
meridian = ''.join(time[5:])

if 'AM' in time:
if ''.join(time[0:2]) == '12':
time = time.replace('12','00')
print(''.join(time[0:5]))
exit()

if len(time) == 7:
part = '0' + time[0]
time = part + time[1:4]
print(time)

if len(time) == 8:
print(''.join(time[0:5]))

else:
if ''.join(time[0:2]) == '12':
print(''.join(time[0:5]))
exit()

mil_time = int(''.join(time[0:2]))
mil_time += 12
mil_time = str(mil_time)

time = list(time)
mil_time = list(mil_time)

for i in range(2):
time[i] = mil_time[i]

print(''. join(time[0:5]))
