I got 2 buttons, respectively named ButtonA , ButtonB . I want the program to print hello, ButtonA and hello, ButtonB if any button is clicked. My code is as follows:
def sayHi(name):
print hello, , name
root = Tk()
btna = Button(root, text = ButtonA , command = lambda: text)
btna.pack()
当我点击ButtonA时,出现错误,<代码>没有定义的。
我理解这一错误,但我如何通过布特纳·沙文来lam。
这一工作应当:
...
btnaText= ButtonA
btna = Button(root, text = btnaText, command = lambda: sayHi(btnaText))
btna.pack()
详情请上。
text is not a function in your case. Just have it as:
value = ButtonA
btna = Button(root, text = value, command = lambda: sayHi(value))
And you will get that working.
