What do you mean by Python literals?

Hi, i need to know What do you mean by Python literals

A literal is some notation that represents a built-in, or fixed value in code. For example, 1 is an integer literal, because whenever you write 1 in code, you’re actually just writing notation that represents the int value of 1. Another example is a string literal, such as "hello world!". When you write that, you’re really just representing a string object.

It’s important to note that in Python, you can’t assign to a literal:

In [1]: 1 = len([1])
  File "<ipython-input-1>", line 1
    1 = len([1])
SyntaxError: cannot assign to literal

This raises an error since you’re trying to assign to 1, which is a literal.
