[Tkinter] How to get & delete details from each input by clicking a button

[Vicolas]

from tkinter import *
import Pmw
root = Tk()
root.title('EntryField')
var = StringVar()
for i in ['First Name:','Surname','Sex:','Age:','Phone Number:','Email Address:']:
    entryfield = Pmw.EntryField(root,labelpos=W,label_text=i,label_width=15,entry_width=24,entry_textvariable=var)
    entryfield.pack(side=TOP,padx=5,pady=5)
button = Button(root,text='Register',command=lambda: print(var.get()))
button.pack(side=LEFT,pady=5,padx=5,expand=YES,fill=X)
button = Button(root,text='Cancel',command=lambda:entryfield.delete(END,var.get()))
button.pack(side=LEFT,padx=5,expand=YES,fill=X)

Hi, please how can I click on the 'Register' button and get all the information inputed into each entryfield.
Also, how can I delete each and every inputed information in the entryfield by clicking on the 'Cancel' button?
And again, please why am I tryping in one entryfield and getting it duplicated on the others. Is there how I can stop it?
Thanks.
