How to convert a list [a,b] to [[a],[b]] in Python? A one line function something like map

Question

I want a single line function to convert a list into group of list. Something like ["a","b"] to [["a"],["b"]] I know this works:

lists = ["a","b"]
newList = []
for i in lists: newList.append([i])

But want something like map function

If you're looking for 'something like map function', take a look at `reduce()` — JoYSword, Jun 13 '19 at 21:09

You can do it with a list comprehension:

lists = [[i] for i in lists]
