Sudo is used to run commands as another user.

To know the sudo rights of your account, you have to run the command sudo -l. Sometimes you are asked to enter your password.

sudo -l
The user1 can use the following commands on target-host:
    (ALL) NOPASSWD: /usr/bin/find
    user2 NOPASSWD: /usr/bin/python3 /home/user2/run.py

The first entry is: (ALL) NOPASSWD: /usr/bin/find
It is possible to run the /usr/bin/find command as any server user, especially root.

sudo /usr/bin/find  

Second entry is: user2 NOPASSWD: /usr/bin/python3 /home/user2/run.py
Here it is possible to run the command '/usr/bin/python3 /home/user2/run.py' as user2.
For this we use the 'sudo' command with the '-u user22' flag

sudo -u user2 /usr/bin/python3 /home/user2/run.py 

If the NOPASSWD option is set, you do not have to enter any passwords. Otherwise, the sudo command asks for the password of the current account. If you are logged in via a webshell, or an ssh connection with private key, you will have to figure out the password.
