A bare except like this is virtually never a good idea:

Something like this would be better:
try:
self.number_of_competitors = int(entered_text.get())
except ValueError:
label.config(text="Enter the number of competitors. Please
enter a number.")
else:
root.destroy()

This will make it call 'get_text' when the button is clicked:
> Button(root, text = "Submit", command = get_text).pack()
This will make it call 'get_text' when the pointer enters the frame:
> root.bind('<Enter>', get_text)
Did you mean '<Return>', i.e. the Return key?
