函数定义在当前符号表中引入函数名称。函数名称的值具有解释器将其识别为用户定义函数的类型。
|
||
|
|
```
|
||
|
|
>>> something = 1
|
||
|
|
>>> type(something)
|
||
|
|
<type 'int'>
|
||
|
|
>>> def something():
|
||
|
|
... pass
|
||
|
|
...
|
||
|
|
>>> type(something)
|
||
|
|
<type 'function'>
|
||
|
|
>>> something = []
|
||
|
|
>>> type(something)
|
||
|
|
<type 'list'>
|
||
|
|
```
|

此值可以分配给另一个名称，该名称也可以用作函数。这是一般的重命名机制：
|
||
|
|
```
|
||
|
|
>>> fib
|
||
|
|
<function fib at 10042ed0>
|
||
|
|
>>> f = fib
|
||
|
|
>>> f(100)
|
||
|
|
0 1 1 2 3 5 8 13 21 34 55 89
|
||
|
|
|
||
|
|
```
