Python内置ascii函数详细介绍

ascii(object)

As repr(), return a string containing a printable representation of an object, but escape the non-ASCII characters in the string returned by repr() using x, u or U escapes. This generates a string similar to that returned by repr() in Python 2.

说明：

1. 返回一个可打印的对象字符串方式表示，如果是非ascii字符就会输出x，u或U等字符来表示。与python2版本里的repr()是等效的函数。

>>> ascii(1)
'1'
>>> ascii('&')
"'&'"
>>> ascii(9000000)
'9000000'
>>> ascii('中文') #非ascii字符
"'\u4e2d\u6587'"
