where is it wrong? if anyone knows then please make it correct.

Question

import math
print("Enter first number ")
a=int(input( ))
print("Enter second number ")
b=int(input( ))
print("Enter third number ")
c=int(input( ))
print("Enter Fourth number ")
d=int(input( ))
print("Distance is ")
e=((c-a)*2)
f=((d-b)*2)
g=(e+f)
h=(math.sqrt(g))
print("Result")
print(h)
import sys
usr_input = input()
if usr_input == "close":
sys.quit(0)

Answer 1

i checked this with calc. seems to be working correctly
Lets say input is 1234
which makes
e = 4
f = 4
g = 8
and
so square root of 8 is 2.828427...
and if you check if it is the square root by doing
h**2
it will result 8.00000000000002 which is basically 8

Answer 2

seems to work just fine. if you are running it on sololearn you have to give all inputs right at the beginning
=5 inputs

Answer 3

h=(math.sqrt(g))
this line it's not working look ahead
