Question

I want to create a list out of my string in python that would show me how many times a letter is shown in a row inside the string.
for example:

my_string= "google"

i want to create a list that looks like this:

[['g', 1], ['o', 2], ['g', 1], ['l', 1], ['e', 1]]

Thanks!

You could use groupby from itertools:

from itertools import groupby
my_string= "google"
[(c, len(list(i))) for c, i in groupby(my_string)]
