This value is a string, which is a series of characters used to represent text. Strings are written with single or double quotes, for example `'Hello'` or `"Hello"`. In future lessons, you'll learn more about working with strings in Python. + When naming variables in Python, there are some important rules you should keep in mind: -- Variable names can only start with a letter or an underscore (`_`), not a number. -- Variable names can only contain alphanumeric characters (`a-z`, `A-Z`, `0-9`) and underscores (`_`). +- Variable names can only start with a letter or an underscore (`_`), not a number. +- Variable names can only contain alphanumeric characters (`a-z`, `A-Z`, `0-9`) and underscores (`_`). - Variable names are case-sensitive — `age`, `Age`, and `AGE` are all considered unique. - Variable names cannot be one of Python's reserved keywords such as `if`, `class`, or `def`. - If you break any of those rules, your Python program will throw a `SyntaxError`:
