Take 2 letters in python

Question

I was making a project, and I came across an unsolved problem.

So for example I have a string: this is book.
Then how to make the string into a list like this: ["th", "is", "is", "bo", "ok"]
Also see that spaces are removed

Answer 1

string ="".join(input().split(' '))

string = [string[i:i+2] for i in range(0,len(string),2)]
print(string)
