You want to spell a string one by one and save it as a list

s = "hello python!"
s.split()

If you do s.split() in the above code, it is saved as ["hello", "python!"] based on the space, right? Instead, I want to save the spelling in ['h', 'e', 'l', ..., '!'] like this, what should I do?

I used str.split(//) in Ruby, but I don't eat it in Python
