Military time problem

Question

First two cases only solve
Have you any idea about other three cases. I try this

date=input()
print(str(int(date[0:2])+12)+date[2:5]) if date[6:8]=="PM" or date[6:8]=="pm" and "00"<=date[0:2]<="11" else print(date[0:5])

Answer 1

if hour=="12" and p_day=="AM":
print("00:{}".format(minutes)).

Answer 2

Also there can be problem like, 1:10 instead of 01:10
