Question

Answer 1

你可以這樣做：

    new_list = []
    list = ['Fruits in ["Apples", "Mangoes"]','Vegetables in ["Carrots", "Onion"]']
    for elem in list:
        # gets the text after the opening bracket and avoids the last character
        brackets = elem.split("[")[1][:-1]
        inside_list = brackets.split(',')

        new_list.append(inside_list)
    print(f'{new_list}')

Answer 2

import re

def extract_items(s):
    return re.compile("(?<=[^\(]')\w+").findall(s)

mylist = ["Fruits in ['Apples', 'Mangoes']","Vegetables in ['Carrots', 'Onion']"]
list1 = list(map(extract_items,  mylist))
print(list1)
