Ruby CGI lib compare with Python CGI lib: Get form value

This is the Ruby  

require 'cgi'

dcgi=CGI.new

dcgi["name"]==dcgi.params["name"][0]

This is the Python
import 'cgi'

form = cgi.FieldStorage()

form["name"].value
But recommend use follow way:
form.getvalue("user", "")   #The second parameter is the default value if the value is not existent

form.getlist("user")

form.getfirst("user","")

都是用字典来存储CGI参数， 只是语法上有所差异， 很接近的设计风格呢。。
