This is the default behavior. You can change the header and printed attributes by using the .output() function >>> C = cookies.SimpleCookie() >>> C["rocky"] = "road" >>> C["rocky"]["path"] = "/cookie" >>> print(C.output(header="Cookie:")) Cookie: rocky=road; Path=/cookie >>> print(C.output(attrs=[], header="Cookie:")) Cookie: rocky=road The load() method of a Cookie extracts cookies from a string. In a CGI script, you would use this method to extract the cookies from the HTTP_COOKIE environment variable. >>> C = cookies.SimpleCookie() >>> C.load("chips=ahoy; vienna=finger") >>> C.output() 'Set-Cookie: chips=ahoy\r\nSet-Cookie: vienna=finger' The load() method is darn-tootin smart about identifying cookies within a string. Escaped quotation marks, nested semicolons, and other such trickeries do not confuse it. >>> C = cookies.SimpleCookie() >>> C.load('keebler="E=everybody; L=\\"Loves\\"; fudge=;";') >>> print(C) Set-Cookie: keebler="E=everybody; L=\"Loves\"; fudge=;" Each element of the Cookie also supports all of the RFC 2109 Cookie attributes. Here's an example which sets the Path attribute. >>> C = cookies.SimpleCookie() >>> C["oreo"] = "doublestuff" >>> C["oreo"]["path"] = "/" >>> print(C) Set-Cookie: oreo=doublestuff; Path=/ Each dictionary element has a 'value' attribute, which gives you back the value associated with the key. >>> C = cookies.SimpleCookie() >>> C["twix"] = "none for you" >>> C["twix"].value 'none for you' The SimpleCookie expects that all values should be standard strings. Just to be sure, SimpleCookie invokes the str() builtin to convert the value to a string, when the values are set dictionary-style. >>> C = cookies.SimpleCookie() >>> C["number"] = 7 >>> C["string"] = "seven" >>> C["number"].value '7' >>> C["string"].value 'seven' >>> C.output() 'Set-Cookie: number=7\r\nSet-Cookie: string=seven' Finis.
