How to use any string from list as a variable?

问题

I would like to know how i could have a variable A to be any random string from ListA and B to be any random string from ListB?

I would like to use this in a voice assistant and Voice would be the string containing the recognized sentence. It should make a google search of anything I say between string A and string B.

import re
import webbrowser

ListA = ["search", "research"]
ListB = ["on google", "using google"]

A = # any string from ListA
B = # any string from ListB

Search = re.search(A + '(.+?)' B + , Voice).group(1)
url = "https://www.google.com/search?q=" + Search
webbrowser.get().open(url)

回答1:

I suggest reading what exists in the random module.

This is one of the things it offers:

list_a = ["search", "research"]
a = random.choice(list_a)
