Python Class is Undefined?

Question

I have written the following class in my .py script. Why does it keep coming back as HTMLEasyPrinting is undefined. That's a function/class in wxPython which I imported with "import wx"

Code:

#Printer Class
class Printer(HtmlEasyPrinting):
    def __init__(self):
        HtmlEasyPrinting.__init__(self)

    def GetHtmlText(self,text):
        html_text = '<h3>Data Results:</h3><p><table border="2">'
        html_text += "<tr><td>Domain:</td><td>Mail Server:</td><td>TLS:</td><td># of Employees:</td><td>Verified</td></tr>"
        for row in root.pt.get_rows():
            html_text += "<tr>"
            for x in range(len(row)):
                html_text += "<td>"+str(row[x])+"</td>"
            html_text += "</tr>"
        return html_text + "</table></p>"

    def Print(self, text, doc_name):
        self.SetHeader(doc_name)
        self.PrintText(self.GetHtmlText(text),doc_name)

    def PreviewText(self, text, doc_name):
        self.SetHeader(doc_name)
        HtmlEasyPrinting.PreviewText(self, self.GetHtmlText(text))

Answer 1

You have a two choices.

One, you can use the full name.

class Printer(wx.HtmlEasyPrinting):

Two, you can import the object from wx

from wx import HtmlEasyPrinting

Based on the documentation, HtmlEasyPrinting lives inside wx.html, so you need to change wx to wx.html everywhere.

Option 1

import wx.html
class Printer(wx.html.HtmlEasyPrinting):

Option 2

from wx.html import HtmlEasyPrinting
