python - How do you join all items in a list?

Question

I have a list and it adds each letter of a word one by one to this list, I don't know what will be in the list until the program is run. How do I join each letter in the list into one word? e.g. turn ['p', 'y', 't', 'h', 'o', 'n'] into ['python'].

Answer 1

a = ['a', 'b', 'c']
res = "".join(a)

You can again convert back to list of letters using :

list(res)
