Any way to automate changing the default linux shell password for Dell OS10 switches?

I am a newbie at using python/netmiko. I have a new bunch of dell OS10 switches and was able to make a lot changes thru netmiko. Howveri am stuck on automating the password change for “linuxadmin” user. How do I go about changing the Linux shell password from default linuxadmin? I plan to keep the shell password same for all switches.

Thanks in advance
