Как получить несколько соответствий regex, от одной строки, в переменную волшебства $matches в Powershell?

import re

match = {}  # create a dictionary of words-to-replace and words-to-replace-with

f = open("filename", "r")
data = f.read()  # string of all file content


def replace_all(text, dic):
    for i, j in dic.items():
        text = re.sub(r"\b%s\b" % i, j, text)
        # r"\b%s\b"% enables replacing by whole word matches only
    return text


data = replace_all(data, match)
print(data)  # you can copy and paste the result to whatever file you like
