使用split（）时如何使标点符号成为单独的项目

Question

I'm writing a program that compresses text by replicating it with a sequence of numbers - but I don't know how to get the program to recognise punctuation as a separate item in the list.

eg, in this sentence with a comma, the comma means that the words 'comma,' and 'comma' are different when using split() . I want to have 'comma' ',' 'comma' instead.

I don't want to get rid of the punctuation - i want it as a separate item in a list

Answer 1

You can use re.split like this:

>>> re.split('([{}])'.format(re.escape(string.punctuation)), "comma,comma")
['comma', ',', 'comma']
