title: Checking if a button has been pressed in python?
body: <p>Code:</p>
  
  <pre><code>import sys
  from tkinter import *
  
  credit = 0
  coins = 0
  choice = 0
  
  
  credit1 = 0
  coins = 0
  prices = [200,150,160,50,90]
  item = 0
  i = 0
  temp=0
  n=0
  choice1 = 0
  choice2 = 0
  
  credit1 = 0
  coins = 0
  prices = [200,150,160,50,90]
  item = 0
  i = 0
  temp=0
  n=0
  choice1 = 0
  choice2 = 0
  
  def insert():
      insert = Tk()
  
      insert.geometry("450x250")
      iLabel = Label(insert, text="Enter coins.[Press Buttons]").grid(row=1, column=1)
  
      tenbutton = Button(insert, text="10p").grid(row=2, column=1)
      twentybutton = Button(insert, text="20p").grid(row=3, column=1)
      fiftybutton = Button(insert, text="50p").grid(row=4, column=1)
      poundbutton = Button(insert, text="£1").grid(row=5, column=1)
  </code></pre>
  
  <p>I am creating a program that simulates a vending machine.
  How would I tell Python to 'check' if  A button has been pressed?
  In pseudocode it would be:</p>
  
  <pre><code>if tenbutton is pressed:
     Add 10p to credit
  </code></pre>
  
  <p>How would I write in Python "if tenbutton is pressed"? Thank you in advance.</p>
