Calling Different Functions tkinter

Question

I'm trying to call different functions based on the inputted text in a Tkinter program.

root=Tk()
tex=Text(root)
tex.pack(side='right')
inputfield = Entry(root)
inputfield.pack(side='bottom')
text = inputfield.get()
if 'weather:' in text:
    inputfield.bind('<Return>', lambda _: weather())
if 'open:' in text:
     inputfield.bind('<Return>', lambda _: program())

root.mainloop()

I'm trying to make it so if the inputted text contains weather: then it will call the weather() function. But if the inputted text contains open: then it opens the program() function. However I cannot figure it out. Anyone have any suggestions?

Answer 1

You are retrieving the text of the Entry before the mainloop. Instead of that, you should check the content inside the callback function:

def callback(event):
    text = inputfield.get()
    if 'weather:' in text:
        weather()
    if 'open:' in text:
        program()

# ...
inputfield.bind('<Return>', callback)

Besides, if you bind two times the <Return> event, the second binding will override the previous one ( unless you pass "+" as the third argument ). However, with only one callback you have enough to control both scenarios.
