Project Euler: Problem 4

https://projecteuler.net/problem=4

A palindromic number reads the same both ways. The largest palindrome made from the product of two 2-digit numbers is 9009 = 91 × 99.

Find the largest palindrome made from the product of two 3-digit numbers.

p=[]                     #empty list

    for y in range(1000):  #gives all combination with x and y <1000 3 digits
        z=x*y                #define z
        if str(z)==str(z)[::-1]:  #added to list if z is palindrome
            p.append(z)
print(max(p))        #gives the largest palindrome
