for dir, dirs, files in (os.walk) 
    print(os.path.join(dir, dirs, files))

 

 

1. Json

import json

my_details = {
    'name': 'John Doe',
    'age': 29
}

with open('personal.json', 'w') as json_file:
    json.dump(my_details, json_file)

 

2. txt

逐行寫入

with open('do_re_mi.txt', 'w') as f:
    f.write('Doe, a deer, a female deer\n')
    f.write('Ray, a drop of golden sun\n')

with open('browsers.txt', 'w') as f:
    web_browsers = ['Firefox\n', 'Chrome\n', 'Edge\n']
    f.writelines("%s\n" % line for line in web_browsers)

with open('browsers.txt', 'w') as f:
    web_browsers = ['Firefox\n', 'Chrome\n', 'Edge\n']
