用python将列表写入文件的有效方法

my_list = ['item1', 'item2', 'item3']
with open('output.txt', 'w') as f:
    for item in my_list:
        f.write(item + '\n')

my_list = ['item1', 'item2', 'item3']
with open('output.txt', 'w') as f:
    f.writelines('\n'.join(my_list))

import json

my_list = ['item1', 'item2', 'item3']
with open('output.txt', 'w') as f:
    json.dump(my_list, f)

import pickle

my_list = ['item1', 'item2', 'item3']
with open('output.txt', 'wb') as f:
    pickle.dump(my_list, f)
