Python 3.2 with Tkinter with webbrowser - search program

As the title suggests, I'm trying to create little search tool with GUI. How I want it to work: When I click the button 'search', open 'https://www.google.com/?gws_rd=cr&ei=qr5cU8GJGMnStAao1YG4BA#q=' + key words that I want to search for. These key words I will type in.

Whole code:

from tkinter import *
import webbrowser

class MainClass():

    def __init__(self,master):
        self.parent=master
        self.gui()

    def gui(self):
        self.Source=StringVar()
        #This next line I just tried out to use 'what' instead of 'str(self.Source) in def search(self)
        what=Entry(myGUI, textvariable=self.Source).grid(row=9, column=2) 

        label4=Label(myGUI, text='Key words:', fg= 'Black').grid(row=9, column=1)

        button4=Button(myGUI, text="  Search  ", command=self.search).grid(row=18, column=1)


    def search(self):
            webbrowser.open('http://google.com/?gws_rd=cr&ei=qr5cU8GJGMnStAao1YG4BA#q=' + str(self.Source.get))



if __name__ == '__main__':
    myGUI=Tk()
    app=MainClass(myGUI)
    myGUI.geometry("300x100+100+200")
    myGUI.title('Google search')
    myGUI.mainloop()

Well, the problem I am having is with this line:

def search(self):
        webbrowser.open('http://google.com/?gws_rd=cr&ei=qr5cU8GJGMnStAao1YG4BA#q=' + str(self.Source.get))

If I leave it as it is and click the search button, it opens google and searches for: 'bound method StringVar.get of tkinter.StringVar object at 0x0301EE90'

If I keep the line, but instead of str(self.Source.get) I use str(self.Source), it again opens the google, but this time it searches for: PY_VAR0

If I use just self.Source, it gives me an error "Can't convert 'StringVar' object to str implicitly" when I press the search button.

So I am a little confused how to correctly use this, please help.

You have to actually call the get method self.Source.get(), otherwise, what you are providing to str is the method, not its return value.

Thus, the whole line would be 

webbrowser.open('http://google.com/?gws_rd=cr&ei=qr5cU8GJGMnStAao1YG4BA#q=' + str(self.Source.get()))
