## 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
```
