TKINTER等待多个按钮按下
已经创建了一个带有y^x的计算器，它使用wait命令来等待x值被按下。等待只等待一个按钮按下。希望它至少等待5个按钮按下，例如-25.3。如何做？
# Create a wait function that will wait for another key press
def wait_variable(self):
self.tk.call('tkwait', 'variable', self.equation)
def power(self):
a = self.get_expression()
self.equation.set(f"{a} ^ b (enter b)")
# Call the wait function
self.wait_variable()
b = self.get_expression()[-1]
power_expression = f"math.pow(float({a}), float({b}))"
_expression = self.get_expression()
self._calculate_expression(power_expression)
Have created a calculator with, among others, y^x and it uses wait command to wait for x value to be pressed. Wait only waits for one button press. Would like it to wait for at least 5 button presses, such as -25.3. How to do this?
# Create a wait function that will wait for another key press
def wait_variable(self):
self.tk.call('tkwait', 'variable', self.equation)
def power(self):
a = self.get_expression()
self.equation.set(f"{a} ^ b (enter b)")
# Call the wait function
self.wait_variable()
b = self.get_expression()[-1]
power_expression = f"math.pow(float({a}), float({b}))"
_expression = self.get_expression()
self._calculate_expression(power_expression)

我想建议您创建一个全局变量并在每个按钮按下将其递增，然后创建一个用每种按下来调用的函数，并检查变量的值，如果var的值为5，执行件，我希望有帮助。
I would like to suggest that you create a global variable and increment it with every button press, then create a function that gets called with every press and checks the value of the variable, if the var had the value of 5, execute stuff, I hope that helps.
