`locals()`函數返回一個字典，其中包含在本地名稱空間中定義的變量。 在全局名稱空間中調用`locals()`與調用[`globals()`](/python-builtin-functions/globals/)相同，并返回代表模塊全局名稱空間的字典。

其語法如下：

```py

locals() -> dictionary containg local scope variables

```

這是一個例子：

```py

#!/usr/bin/python3

from pprint import pprint

a = 10

b = 20

def foo():

x = 30 # x and y are local variables

y = 40

print("locals() = {0}".format(locals()))

pprint(locals()) # same as calling globals()

print('*' * 80)

print("locals() == globals()? ", locals() == globals())

print('*' * 80)

foo()

```

**預期輸出**：

```py

{'__builtins__': ,

'__cached__': None,

'__doc__': None,

'__file__': 'module1.py',

'__loader__': <_frozen_importlib_external.sourcefileloader object at>,

'__name__': '__main__',

'__package__': None,

'__spec__': None,

'a': 10,

'b': 20,

'foo': ,

'pprint': }

********************************************************************************

locals() == globals()? True

********************************************************************************

locals() = {'y': 40, 'x': 30}

```

試試看：

```py

from pprint import pprint

a = 10

b = 20

def foo():

x = 30 # x and y are local variables

y = 40

print("locals() = {0}".format(locals()))

pprint(locals()) # same as calling globals()

print('*' * 80)

print("locals() == globals()? ", locals() == globals())

print('*' * 80)

foo()

```
