Question

In python programming whether a text in a palindrome will ignore punctuation, spaces and cases or will it consider it???
i need a python program to prove "Rise to vote, sir." as a palindrome.. can anyone help me???

Answer 1

Strings are actually arrays of characters. Therefore, you just check if the 0th character is equal to the len(string) - 1th character. You can just recurse until the beginning index is greater than or equal to the ending index.

Answer 2

Each character, including punctuation, contained in the string array is actually stored as a unique uni-code value integer value. It is your program that determines how these values are interpreted, rather than Python.

Answer 3

To answer your question, yes, python will consider punctuation to be a character. An example of what you are looking for is:

Forward = "Rise to vote, sir"
Backward = Forward[::-1]
if lower(Forward) == lower(Backward)
print "Palindrome!"

Of course, this will fail as the comma will mess up the comparison. If your assignment mandates that punctuation should not affect whether something is a palindrome, you can simply walk through the string first and only copy alpha characters to a new string then run the comparison on that.
