Why is my Tkinter button's command executing immediately instead of on click?

Unexpected Button Triggering in Tkinter: Understanding Function References

In Tkinter, when creating a button, you can specify a command that will be executed when the button is clicked. However, in your code sample, the provided command is being executed immediately when the button is created.

To understand why this is happening, consider the following snippet:

b = Button(admin, text='as', command=button('hey'))

This code is equivalent to:

result = button('hey')
b = Button(admin, text='as', command=result)

When you call button('hey') inside the command parameter, you're invoking the function and executing it immediately. As a result, the code print('hey') and print('het') are printed before the button is actually clicked.

To resolve this issue, you need to pass a reference to the function, without executing it. To do this, simply omit the parentheses:

b = Button(admin, text='as', command=button)

This will pass a reference to the button function, and it will be executed when the button is clicked, not when it's created.

Alternatively, you can use lambda functions to create an anonymous function that calls the original function with the desired argument:

b = Button(admin, text='as', command=lambda: button('hey'))
