id是python中的关键字吗? [英] Is `id` a keyword in python?

问题描述

我的编辑器(TextMate)用其他颜色(当用作变量名时)显示id，而不是通常的变量名.是关键字吗?我不想给任何关键字加上阴影...

My editor (TextMate) shows id in an other colour (when used as variable name) then my usual variable names. Is it a keyword? I don't want to shade any keyword...

推荐答案

id在Python中不是关键字，而是

id is not a keyword in Python, but it is the name of a built-in function.

关键字是:

and       del       from      not       while
as        elif      global    or        with
assert    else      if        pass      yield
break     except    import    print
class     exec      in        raise
continue  finally   is        return
def       for       lambda    try

关键字是无效的变量名称.以下将是语法错误:

Keywords are invalid variable names. The following would be a syntax error:

if = 1

另一方面，诸如id或type或str的内置函数可以被遮盖:

On the other hand, built-in functions like id or type or str can be shadowed:

str = "hello"    # don't do this
