Code Coach "MILITARY TIME"

Question

inp = str(input())
pisah = []
pm = "PM"
duabelas = '12'
if pm in inp:
if duabelas in inp:
for x in inp.split(" "):
pisah.append(x)
print(pisah[0])
else:
for x in inp.split(":"):
pisah.append(x)
a = ' '.join(pisah)
b = a.split(" ")
c = int(b[0]) + 12
pisah.append(str(c))
print(b[1] + ":" + b[2])
else:
if duabelas in inp:
for x in inp.split(":"):
pisah.append(x)
a = ' '.join(pisah)
b = a.split(" ")
c = int(b[0]) - 12
pisah.append(str(c))
print(b[1] + ":" + b[2])
else:
for x in inp.split(" "):
pisah.append(x)
print(pisah[0])
From that code, why I got wrong at Test Case #3 and Test Case #5. Even that is manual method, but I think its right.

Answer 1

I don't fully not understanding your logic.. but just change your original code to output
If hour ==12 or 1<=hour<=9 :
print("0+hour")
But you have lot redundant code
try to remove and write only once outside if , if you doing same in both (if, else) parts.
for jam in splitspasi:
hasil.append(jam)
print(hasil[0])
is just same as splitsasi[0]. (I think)
What if input is 1:11 AM (seconds is 12,, 11, or 10 )
Output is 1:11
It is true for "11" in splitspasi, accidentally lead wrong by your logic.
Malik Hafid Sidiq
Simple steps:
Take input and split with space
if list[1] is AM
Do hr%12 , if below 10 append 0.
if list[1] is PM, if hr!=12, hr+12, else 12
You can go with your logic. just try to append 0 for input 12, and 1-9 AM hours...

Answer 2

Malik Hafid Sidiq
Tested these sample cases , getting wrong..
Input 12:00 AM => output need is 00:00
1:00 AM => 01:00
All you need is hr is in double digits if it is in single digit..

Answer 3

Sorry, I am noob in python and this SoloLearn

Answer 4

okay, so i would start off by splitting the time up with the “hello”.split(“e”) method to get “12” “00” and “AM” (using the method twice). second after doing the neccesary math, you can turn it back into double digits by using
“%02d” % integer
which pads the number with zeroes (two in this case, hence the two). The D stands for digit, and the % is the special formatter operator in this case (if we were working just with numbers and not a string, it would be modulus).

Answer 5

Sorry Im very newbie in python, so I still use logic

Answer 6

hasil.append(jam)
gabunglagi = ' '.join(hasil)
pisahlagi = gabunglagi.split(" ")
konvert = "0" + pisahlagi[0]
print(konvert + ":" + pisahlagi[1])

Answer 8

This is an answer to the code coach. I put comments throughout to explain it. READ AND UNDERSTAND BEFORE USING. https://code.sololearn.com/ckyTBARScyEA/?ref=app

Answer 9

Calvin Thomas Umm... that’s more conpact but almost unreadable. besides, you’re not supposed to post code answers with no explanation.

Answer 10

David Ordás the lesson is meant to teach about string formatting, not the datetime module.

Answer 11

Try this..
t=input().strip()
numt,ch=t.split(' ')
hour,minute=numt.split(':')
hour=int(hour)
if ch=='AM':
if hour<10:
print("0{}:{}".format(str(hour),str(minute)))
else:
print("{}:{}".format(str(hour),minute ))
elif ch=='PM':
if hour==12:
print("00:{}".format(str(minute)))
else:
print("{}:{}".format(str(hour%12+12),minute))

Answer 12

David Ordás I am a newbie in python, so I just using a logic to solve the problem.
Thanks for you sugestion..

Answer 13

for future reference, please use code playground to share code.
this code looks unneccesarily complicated, like you are trying to deal with everything in the form of strings, or lists, or anything but integers.

Answer 14

are you using the app?

Answer 15

Who gave you this assignment?

Answer 16

i forgot to mention using the int(“42”) function to turn them into numbers.

Answer 17

It is in medium Code Coach
I was try from easy until medium using a nub method
But this task is already by my self
You will get headache if read my code....

inp = str(input())
splitspasi = inp.split(" ")
splittitik = inp.split(":")
hasil = []
if "PM" in inp:
if "12" in splittitik:

hasil.append(jam)
print(hasil[0])
else:
for jam in splittitik:
hasil.append(jam)
gabunglagi = ' '.join(hasil)
pisahlagi = gabunglagi.split(" ")
konvert = int(pisahlagi[0]) + 12
print(str(konvert) + ":" + pisahlagi[1])
else:
if "12" in splittitik:
for jam in splittitik:
hasil.append(jam)
gabunglagi = ' '.join(hasil)
