ans=""
if a[-2:]=="PM":
if b[1]==":":
ans=str(int(b[0])+12)+b[1:]
elif b[0:2]== "12":
ans="12"+b[2:]
else:
ans=str(int(b[0:2])+12)+b[2:]

if b[1]==":":
ans="0"+b[0:]
elif b[0:2]=="12":
ans="00"+b[2:]
else:
ans=b
print(ans)

Answer 2

It should return in XX:XX format.For example, if I give input :
1:00 AM
it should return 01:00 not 1:00
