 Project Euler
Step1:  Then I created an empty list, which would hold all the palindromes created from multiplying those three digit numbers.
Step2:  Using two for loops, I looped through all the values in a, multiplying them by all the possible values of b, and calling the product p.  Using an if statement, I turned the product into a string and compared whether it was the same fowards as backwards.  If it was, I appended it to my list of palindromes.
Step3:  Finally, I printed the maximum palindrome using the built in max function.

Python Code:
a = range(100, 1000)
b = range(100, 1000)
Explanation: 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.
First, I defined two lists which hold the values of all three digit numbers

lst = []

for x in a:
    for y in b:
        p = x * y
        if str(p) == str(p)[::-1]:
            lst.append(p)
