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
