What Are Python Literals?

[Julie]

Values like integers, floats, strings and others are immutable and can't be changed, but you can change what a variable refers to.

Awesome. Another question to help clarify things. When I hear immutable vs. mutable, I think of the list data type (mutable) vs. tuple data type (immutable). But, I also see list and dictionary data type included as literals...even though they are both mutable. Are these exceptions to the rule for literals?

Also, would you define a literal as the value as you see it? What exactly does that mean? Can you compare the differences between a literal and non-literal? What makes one a literal and the other not a literal?
