Cloning tkinter Buttons with other function

Question

right now I am working on a python phone book with following layout:

|Name | Surname |

Now I want to create a button for each contacts Name and Surname, so 2 buttons for 1 contact * n. If I press on the Name or Surname a box with more details of the contact should open. Can anyone please help me?

I tried following so far:

prename = ["John", "Jack"]
surname = ["Tompson", "Daniels"]
x = 0
y = 0
for pn in prename:
    pre = Button(main, text=pn)
    pre.grid(row=x, column=0)
    x += 1
for sn in surname:
    sur = Button(main, text=sn)
    sur.grid(row=y, column=1)
    y += 1

You need to associate the buttons with the functions you want to be executed when you press them. I use lambda to pass the specific name to the function call.

Also; its more readable to use enumerate when you want a loop index.

from tkinter import *

main = Tk()

prename = ["John", "Jack"]
surname = ["Tompson", "Daniels"]

def get_prename(n): # Callback function for prename buttons
    print(n)

def get_surname(n): # Callback function for surname buttons
    print(n)

for x, pn in enumerate(prename):
    pre = Button(main, text=pn, command=lambda pn=pn: get_prename(pn))
    pre.grid(row=x, column=0)

for y, sn in enumerate(surname):
    sur = Button(main, text=sn, command=lambda sn=sn: get_surname(sn))
    sur.grid(row=y, column=1)
