4.3 of Stepik "Repeating Loops"

Hello can anyone please explain what the
more_people=more_people.lower()
is?

What does the “.” “lower” accomplish or mean?

Greetings. While I’m not 100% sure because I don’t know what language this is in. Python? I’m guessing.

It most likely is a function that returns a string with all alphanumeric characters converted to lower case.
