Question

python中quote函数是什么意思，怎么用

Answer 1

这个函数的说明如下： 
urllib.quote(string[, safe])¶
Replace special characters in string using the %xx escape. Letters, digits, and the characters '_.-' are never quoted. By default, this function is intended for quoting the path section of the URL. The optional safe parameter specifies additional characters that should not be quoted — its default value is '/'.
Example: quote('/~connolly/') yields '/%7econnolly/'.

大概的意思就是： 用 %xx 替换字符串中的特殊字符， 主要用来替换URL中的路径分隔符；因为在URL标准中有的字符不允许编码在URL中， 如果希望使用其他字符就需要进行编码。

希望对你有帮助

你好：
下面是quote的API：

quote(s, safe='/')
quote('abc def') -> 'abc%20def'

Each part of a URL, e.g. the path info, the query, etc., has a
different set of reserved characters that must be quoted.

RFC 2396 Uniform Resource Identifiers (URI): Generic Syntax lists
the following reserved characters.

reserved = ";" | "/" | "?" | ":" | "@" | "&" | "=" | "+" |
"$" | ","

Each of these characters is reserved in some component of a URL,
but not necessarily in all of them.

By default, the quote function is intended for quoting the path
section of a URL. Thus, it will not encode '/'. This character
is reserved, but in typical usage the quote function is being
called on a path where the existing slash characters are used as
reserved characters.
