The following identifiers are used as reserved words, or keywords of the language, and cannot be used as ordinary identifiers. They must be spelled exactly as written here:
and del for is raise assert elif from lambda return break else global not try class except if or while continue exec import pass yield def finally in print
Note that although the identifier
as can be used as part of the
syntax of import statements, it is not currently a reserved
In some future version of Python, the identifiers
None will both become keywords.
