How can you obtain a list of all user accounts, including system and hidden ones, in a Linux system?

In Linux, the list of all accounts, including system and hidden ones, is stored in the /etc/passwd file. To obtain this list using Python, you can read and process this file:

with open('/etc/passwd', 'r') as f:
    users = [line.split(':')[0] for line in f.readlines()]

print(users)

This code will output the names of all users. For more detailed analysis, you can use the pwd module:

import pwd

users = [user.pw_name for user in pwd.getpwall()]
print(users)

The pwd module returns all user records, including system and hidden ones, which is more convenient and reliable than manually parsing the file.
