Answer 2

Hint:
Get the string length, decrement it by 1, that's the index of last character to check.

Since you will be checking each character from both end of the string, you'll need half the string length as your loop range limit let it be <half>. Remember to divide with floor division operator to have it an integral value.

Run a for loop <i> with <half> as range limit.

During loop see if character on the i-th position NOT equal to the character on the <half> - <i> position. If so, immediately return False.

If the loop completed then return True.

P.S. Don't ask for code, you won't get it from me XD

Can you show us your attempt first?

Answer 4

def pal(s):
for i in range(0):
pass
return s == s[::-1]
