Noob with a stupid question

Stupid question time! I love this part… ok.

The difference between a variable and a constant? I see both describe something, like a noun, but a constant is Capitalized. So I did notice a difference as I tried to give an example below:

Bill = “123 Anywhere St., New York, NY 123456”
bill = 100_dollars

“Bill” is a place, I get that. It doesn’t change. But “bill” would not either. It is defined as a 100 dollar bill. Maybe I am thinking too hard. Thanks in advance.

Constant is used for a value that won’t likely to change throughout the program’s running life. Like you’d put Pi = 3.14 as a Constant cause this value is not going to change as more code is being executed. Variable is used to hold everything else
