|  | --- | ||
|  | A function definition introduces the function name in the current symbol table. The value of the function name has a type that is recognized by the interpreter as a user-defined function. | ||
|  | 
 | ||
|  |     >>> something = 1 | ||
|  |     >>> type(something) | ||
|  |     <type 'int'> | ||
|  |     >>> def something(): | ||
|  |     ...     pass | ||
|  |     ... | ||
|  |     >>> type(something) | ||
|  |     <type 'function'> | ||
|  |     >>> something = [] | ||
|  |     >>> type(something) | ||
|  |     <type 'list'> | ||
|  | 
 | ||
|  | This value can be assigned to another name which can then also be used as a function. This serves as a general renaming mechanism: | ||
|  | 
 | ||
|  |     >>> fib | ||
|  |     <function fib at 10042ed0> | ||
|  |     >>> f = fib | ||
|  |     >>> f(100) | ||
|  |     0 1 1 2 3 5 8 13 21 34 55 89 |
