What's wrong in this code?

Question

I tried solving military time code coach challenge! 3 of the 5 test were successful. 2 hidden tests were unsuccessful.

This is the code:
x = input()

var = x.split(" ")
var2 = var[0].split(":")

if var[1].upper() == "PM":
if var2[0] == "12":
print ("12" + ":" + var2[1])
else:
var3 = str(int(var2[0]) + 12 )
print (var3 + ":" + var2[1])
else :
if var2[0] == "12":
print ("00" + ":" + var2[1])
else:
print (var[0])

What is the mistake?

Answer 1

You just have to make it
print ("0" + ":" + var2[1])
one zero instead of two and it will pass the cases

Namit Jain and Brian thanks alot...
BTW, Namit, what does zfill does?

Answer 4

Hind Biswas Or you can simply do:
if var[0].index(":") == 1:
print("0" + var[0])
else:
print(var[0])
But doing this would be inefficient! Here zfill would be more efficient!

Zfill does the same task! It checks that if the length of var[0] is less than 5 then it will add "0"s before it until it's length becomes 5
Like:
a = "123"
print(a.zfill(5))
Output: 00123

Answer 5

Brian I fixed that. Still not working..... I edited the code check it

Answer 6

Your correction is good.

From other discussion questions I find that Code Coach needs a leading zero on the output of single-digit hours.

Answer 7

Is it working now?
Or still facing the problem?
