ECS count

from tkinter import *
import tkinter.simpledialog
import tkinter.messagebox

root = Tk()
w = Label(root, text="Count")
w.pack()

x = 1
while x <= 5:
    tkinter.messagebox.showinfo("x", "x equals " + str(x))
    x += 1


# Run the program and answer the following:
# 1. How many messages are output?
# 2. What do you think the x += 1 does?
# 3. What would you have to change to make the program output only 3 messages?
# 4. This part is to be checked off when you get it running.  Change the code to
#    count to 10 by 2s.  It should stop after it gets to 10.  Write down your changes.
#   Example:
#       2
#       4
#       6
#       8
#          10
# 5. In your own words, summarize what the while does.
