## Python关键字
|
||
|
||
Python有一个不能用作标识符（变量名）的[关键字](https://docs.python.org/3/reference/lexical_analysis.html#keywords)列表。尝试将这些关键字中的任何一个用作变量将创建**语法错误，**并且不会运行您的Python脚本：
|
||
```
|
||
>>> False = "Hello campers!"
|
||
File "<stdin>"
|
||
SyntaxError: can't assign to keyword
|
||
|
||
>>> break = "Hello campers!"
|
||
File "<stdin>", line 1
|
||
break = "Hello campers!"
|
||
^
|
||
SyntaxError: invalid syntax
|
||
```
