I want to write a code in phyton that prints only letters from input but skips two and prints one.

Question

I want my program to do this;
input = 2ab4c#fd56gjl
output = afj

So it should completely ignore any character other than letters and print the letters by skipping 2.

Is there a way to do it? Should i use for loop?

Answer 1

1) post your attempt first
2) For loop is neccecary (2 I think)

Answer 2

Just try using for-loops first

(Hint: the 3rd parameter in the range() function is the step)
