python---实现读txt文件随机点名

import random
list_names = []
list_names2 = []
with open("names.txt", "r", encoding="utf-8") as fr:
    list_names = fr.readlines()
    for i in list_names:
        temp_line = i.strip()   # 去除每行的\n
        list_names2.append(temp_line)
print(list_names2)
random_index = random.randint(0, len(list_names2)-1)
print(random_index)
print(list_names2[random_index])
