块作用域一般用于控制流,比如 if,while 和 for 循环。但是拥有块作用域的语言一般都会允许使用“裸露”的块,这样就可以在块中定义辅助变量并使用,在块终结时销毁。 块可以用来隐藏名字绑定。如果在块的外面定义了 n,在块的里面也可以定义名叫 n 的变量,它会遮盖外面的 n。但是这样的风格一般被认为是不好的,因...
The solution to this is to make all lines in the same Python code file use either tabs or spaces, but not both. For the code blocks above, the fix would be to remove the tab and replace it with 4 spaces, which will print'done'after theforloop has finished. ...
