We can have a messagebox pop up when a button is clicked.
```python
def show_version():
	messagebox.showinfo("Version", "You are using version 2.0")
button = tk.Button(text="show version",
					foreground="red",
					command=show_version)
button.pack()
```

messagebox is like a pop-up window that can be used to show user addition info or ask user a yes/no question.
First we need to import the module:
```python
from tkinter import messagebox
```
We then create a messagebox and call one of the built-in functions. We pass title text and message in the function.
```python
messagebox.showinfo("Title", "Enter message here")
```
