Q$\mathrm{.}1)$ Given a string, write a python function to check if it is palindrome or not. A string is said to be a palindrome if the reverse of the string is the same as the string.

For example, "radar" is a palindrome, but "radix" is not a palindrome.

def is$\_$palindrome$($word$)$:

$i=-1$

for $c$ in word:

if

return False

$i=$

if

return True

print$($is$\_$palindrome$(\text{'}$racecar$\text{'}))$

print$($is$\_$palindrome$(\text{'}$deed$\text{'}))$

print$($is$\_$palindrome$(\text{'}$turkey$\text{'}))$
