python tkinter set askopenfilename to entry : I'm trying to set askopenfilename to entry box. But I don't know how to do it. Please help me out. I would greatly appreciate it.

    import Tkinter as tk
    from tkFileDialog import *
    import ttk
    
    
    class ESA(tk.Tk):
        def __init__(self,*args,**kwargs):
            tk.Tk.__init__(self,*args,**kwargs)
            container = tk.Frame(self)
    
            container.pack(side="top", fill="both", expand=True)
            container.grid_rowconfigure(0, weight=1)
            container.grid_columnconfigure(0, weight=1)
    
            self.frames={}
            for f in (newProject, existingProject, exportProject):
    
                frame = f(container, self)
                self.frames[f] = frame
                frame.grid(row=0, column=0, sticky = "nsew")
    
            self.show_frame(newProject)
        def show_frame(self, cont):
            frame = self.frames[cont]
            frame.tkraise()
    
    class newProject(tk.Frame):
        
        def load_file(self):
            global fname,logo
            
            self.fname = askopenfilename(initialdir=r"C:\Users",filetypes=(
                                            
                                                ('JPEG / JFIF','*.jpg'),('Portable Network Graphics','*.png'),('Windows Bitmap','*.bmp'),
                                               ("All files", "*.*") ))
            newProject.__init__.clientLogoEntry.delete(0, END)
            newProject.__init__.clientLogoEntry.insert(0, self.fname)
            
            
    
    
            
    
    
        def __init__ (self, parent, controller):
      
            tk.Frame.__init__(self,parent)
         
            stepOne = tk.LabelFrame(self, text=" 1. Configuration:")
            stepOne.grid(row=1, columnspan=7, sticky='WE', \
                         padx=5, pady=5, ipadx=5, ipady=5)
            
            logo = tk.StringVar()
            clientLogoEntry = tk.Entry(stepOne, textvariable=logo)
            clientLogoEntry.grid(row=4, column=1, sticky="WE", pady=2)
            stepOne.button = tk.Button(stepOne, text="Browse...", command=self.load_file, width=10)
            stepOne.button.grid(row=4, column=7, sticky="W")

It's giving me this error
