How can I use python itertools.groupby() to group a list of strings by their first character?

Question

I have a list of strings similar to this list:

tags = (\'apples\', \'apricots\', \'oranges\', \'pears\', \'peaches\')

How should I go about

Answer 1

>>> for i, j in itertools.groupby(tags, key=lambda x: x[0]):
    print(i, list(j))


a ['apples', 'apricots']
o ['oranges']
p ['pears', 'peaches']
