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

I'll play with this a bit.

** Note ** Following code uses f-string which requires python 3.6 or newer

Here's how I would do it, tested and works well:

from tkinter import *
import Pmw

class MyForm:
    def __init__(self):
        self.root = Tk()
        self.root.title('EntryField')
        self.form = {}
        self.fields = ['First Name:','Surname','Sex:','Age:','Phone Number:','Email Address:']
        self.build_form()
        self.root.mainloop()

    def build_form(self):
        for field in self.fields:
            curfield = self.form[f'{field}'] = {}
            curfield['var'] = StringVar()
            curfield['widget'] = Pmw.EntryField(
                self.root, 
                labelpos= 'w',
                label_text=field,
                label_width=15,
                entry_width=24,
                entry_textvariable = curfield['var']
            )
            curfield['widget'].pack(side=TOP,padx=5,pady=5)

        button_a = Button(
            self.root,
            text='Register',
            command=self.register_values)
        button_a.pack(side=LEFT,pady=5,padx=5,expand=YES,fill=X)

        button_b = Button(
            self.root, 
            text='Cancel',
            command=lambda: self.clear_entry(self.root.focus_get().cget('text')))
        button_b.pack(side=LEFT,padx=5,expand=YES,fill=X)

    def clear_entry(self, whence):
        field = self.fields[int(whence[whence.index('VAR') + 3:])]
        self.form[field]['var'].set('')

    def register_values(self):
        for key in self.form.keys():
            curfield = self.form[key]
            print(f"{key}: {curfield['var'].get()}")


if __name__ == '__main__':
    MyForm()
