How to check for palindrome using Python logic

Question

I m trying to check for a palindrome with Python  The code I have is very for-loop intensive   And it seems to me the biggest mistake people do when going from C to Python is trying to implement C logic using Python  which makes things run slowly  and it s just not making the most of the language   I see on this website  Search for  C-style for   that Python doesn t have C-style for loops  Might be outdated  but I interpret it to mean Python has its own methods for this   I ve tried looking around  I can t find much up to date  Python 3  advice for this  How can I solve a palindrome challenge in Python  without using the for loop   I ve done this in C in class  but I want to do it in Python  on a personal basis  The problem is from the Euler Project  great site By the way    def isPalindrome n       lst    int n  for n in str n       l len lst      if l  0    l  1          return True     elif len lst  2  0          for k in range  l                    else          while  k lt    l-1  2                if  list                               for i in range  999  100  -1       for j in range  999 100  -1           if isPalindrome i j               print i j              break   I m missing a lot of code here  The five hashes are just reminders for myself   Concrete questions    In C  I would make a for loop comparing index 0 to index max  and then index 0 1 with max-1  until something something  How to best do this in Python  My for loop  in in range  999  100  -1   is this a bad way to do it in Python  Does anybody have any good advice  or good websites  or resources for people in my position  I m not a programmer  I don t aspire to be one  I just want to learn enough so that when I write my bachelor s degree thesis  electrical engineering   I don t have to simultaneously LEARN an applicable programming language while trying to obtain good results in the project   How to go from basic C to great application of Python   that sort of thing  Any specific bits of code to make a great solution to this problem would also be appreciated  I need to learn good algorithms   I am envisioning 3 situations  If the value is zero or single digit  if it is of odd length  and if it is of even length  I was planning to write for loops      PS  The problem is  Find the highest value product of two 3 digit integers that is also a palindrome

A pythonic way to determine if a given value is a palindrome:

str(n) == str(n)[::-1]

Explanation:

We're checking if the string representation of n equals the inverted string representation of n
The [::-1] slice takes care of inverting the string
After that, we compare for equality using ==
