You broke a golden rule: Never ever remove elements from a list while iterating it. Copy word to word1 Iterate word1 delete from word or use filter, if you are familiar with it.

Alexandr Thank you I solved the problem but what does it mean why you add that?

Oma Falk if i am not mistaken you can in fact remove while iterating if you iterate from end to start, which prevents the skipping. unsure if it is advisable to do so... 😅😅😅

s=input() for j in range(len(s)-1,-1,-1): if(s[j].isalpha() or s[j]==" "): print(s[j],end="")

1. Why do you reverse the list two times? 2. Why do you convert string to list (and then make another string out of the list just to print it)? 3. You miss the space ('\s') in the list. 4. Why is there `a=0` in the code? You can just use a string and remove chars from it, i.e. replace it with nothing: ``` for i in word: if(i not in list): word = word.replace(i, '') ``` (and then print it). Here is my solution: https://code.sololearn.com/crr5zo9SXEMG/

Alexandr but the part which is I didn't understand is why this changed result. The items in list is same and name also but result different why?

meow , OK, then still you can use only string, no need for list, and you have to add space to the alphabet, plus reverse the string only once. :)
