how do i fix 'int' object is not iterable error

Question

Hello i'm new in python and im stuck with this error. Can you explain me what am i doing wrong? Also is the math import necessary?

The consept is to find if the word is palindrome.

Here is my code:

  #palindrome
import math #do i need it?

wrd=input("give me a word ")
key=False

length=int(len(wrd)/2 +1)

for i in length:
    for j in length:
        if i==j:
            pass
        else:
            key=True

if key==False: print("palindrome")
else: print("not palindrome")

Answer 1

You do not need to import math

Use range() function -

wrd=input("give me a word ")
key=False

length=int(len(wrd)/2 +1)

for i in range(length):
    for j in range(length):
        if wrd[i]==wrd[j]:
            pass
        else:
            key=True

if key==False: print("palindrome") # This is generally bad practice
else: print("not palindrome") # Use indentation so that it is more readable
