Python module providing a series of functions to generate various forms of HTML element, for use in CGI scripts. Will be expanded as and when I need more elements!

mycgi.py

# UTILITY FUNCTIONS
def preamble():
    """Prints the mandatory opening lines of any CGI script."""
    print "Content-Type: text/html"
    print

def parseCss(css):
    """Convert a CSS class or id name into a string of the form class=var or id=var, with quotes around var.

    String css  -> css tag to convert
     - a class name should be given with a leading '.', e.g. '.myClass'
     - an ID name should be given with a leading '#', e.g. '#myId'
    """
    try:
        if (css[0] == "."):
            return ' class="{0}"'.format(css[1:])
        elif (css[0] == "#"):
            return ' id="{0}"'.format(css[1:])
        else:
            return ''
    except TypeError:
        return ''


# HTML HEADER ELEMENTS
def title(text):
    """Produce an HTML title.

    String text -> text to place within the title
    """

    print "<title>{0}</title>".format(text)

def link(href):
    """Produce an HTML link tag.

    String href     -> href of the stylesheet to link to
    """

    print '<link rel="stylesheet" type="text/css" href="{0}">'.format(href)


# HTML BODY ELEMENTS
def h(level, text, *css):
    """Produce an HTML heading.

    int level   -> which level of heading to print
    String text -> the text of the heading
    *String css -> optional CSS class and id tags
    """

    cssTags = ""
    for tag in css:
        cssTags += parseCss(tag)
    print "<h{0}{1}>{2}</h{0}>".format(level, cssTags, text)

def p(text, *css):
    """Produce an HTML paragraph.

    String text -> the text of the heading
    *String css -> optional CSS class and id tags
    """

    cssTags = ""
    for tag in css:
        cssTags += parseCss(tag)
    print "<p{0}>{1}</p>".format(cssTags, text)

def tr(header, data, *css):
    """Produce an ordinary row for an HTML table.

    bool header         -> whether the row is a header row or not (True for header)
    [String] data       -> list of data to insert into the row
    *String css         -> optional css tags

    cssTags = ""
    for tag in css:
        cssTags += parseCss(tag)

    print "<tr{0}>".format(cssTags)
    for d in data:
        print "<{0}{1}>{2}</{0}>".format("th" if header else "td", cssTags, d)
    print "</tr>"

Added functions to print title and link tags, as well as a function to iteratively print cells in a table
