Python Script:

  import cgi form = cgi.FieldStorage # print HTTP / HTML Header Content Print "" "Content-Type: Text / HTML & lt ;! DOCTYPE HTML Public" - // W3C // DTD XHTML 1.0 Strongly //n "" http://www.w3.org/TR/xhtml1/ DTD / xhtml1 -strict.dtd ">  gt; Top & gt; & lt; title & gt; Order Form & lt; / title & gt; & lt; / head & gt; ; & Lt; body & gt; "H1> Kanthouro Japanese Bar & Restaurant"  "Print" & lt; h2 & gt; Customer Receipt & lt using "Print HTML Body Form Data Print" ; / H2 & gt; Print "& lt; p & gt; Customer Name:", ["custName"] form.

form = cgi.fieldStorage Go to field storage yourself form Instead of providing an example of FieldStorage :

  form = cgi.FieldStorage ()
