for project euler number 4 i am just wondering what is wrong with my code. have been knacking my brain and i do not know how, this is on python

Question

x=100
y=100
z=str(x*y)
k=[]
while x<=999 and y<=999:
    if z==int(z[::-1]):
        k.insert(z)
    x+=1
    y+=1
print(k)

this just produced an empty bracket, i want to know why and how i can fix this. thanks

Answer 1

if z==int(z[::-1]):

This condition is always false because z never changes in the loop, and because z is a string so it will never equal an int

After fixing that your code will still fail because x and y are always equal.
