Somebody explain me this python Code!

Question

This is something new to me. I have never seen this code before.

print('YNEOS'[5%~int(input())%2::2])

I know what is the outcome of the code but has no idea how this work, please explain

Answer 1

:: is called slicing, it's syntax is
start:stop:step
here, start includes 5%~int(input())%2
stop is between : : which means everything in the string 'YNEOS' and 2 is the step

~int(input()) is taking user input and producing it's one's complement

so what ever will be the value of the expression given in "start" then according to that

the string 'YNEOS' will be sliced

for example if value of start came out 1

then we have

print( 'YNEOS'[ 1::2 ] ) will PRINT "NO"
HOW???

start = 1
so slicing of string will start from index 1 which is "N"
and step value is 2 it means index will jump 2 steps forward at index (1+2) = 3. the element at index 3 is "O"

HENCE, output will be "NO"
