Python identifiers

Python identifiers

Variables are examples of identifiers. Identifiers are names given to identify something. There are some rules you have to follow for naming identifiers:

1.  The first character of the identifier must be a letter of the alphabet (upper or lowercase) or an underscore ('_').
2.  The rest of the identifier name can consist of letters (upper or lowercase), underscores ('_') or digits (0-9).
3.  Identifier names are case-sensitive. For example, myname and myName are not the same. Note the lowercase n in the former and the uppercase N in te latter.
4.  Examples of valid identifier names are i, __my_name, name_23 and a1b2_c3.
5.  Examples of invalid identifier names are 2things, this is spaced out and my-name.
