How to change default ssh user for ansible host

Can anyone please help with steps to change default ssh user to some other user for ansible host

Edit the Inventory File and you can specify the SSH user for individual hosts or for groups of hosts.

For an Individual Host: Add the ansible_user variable to the host definition.

[mygroup]
myhost1 ansible_host=192.0.2.1 ansible_user=mynewuser

For a Group of Hosts: Use the ansible_user variable under the group definition.

[mygroup:vars]
ansible_user=mynewuser

Or if you want to change the user on the command line use -u or --user
