calculadora de Python

Implementación de la calculadora Python:

wx.TextCtrl (control de entrada de texto), esta es la pantalla de visualización de la calculadora. Cuando hace clic en el número, use el método AppendText para agregarlo. número al final del texto Para Al sacar números, use el método GetValue Al hacer clic en el operador, borre el número en el cuadro de texto (guárdelo primero) y use el método Borrar y luego guarde el operador. signo igual, almacene el segundo operando y luego use int. El método convierte la cadena en un número. Después del cálculo, el método SetValue se usa para enviar el resultado al cuadro de texto. El código específico es el siguiente: import?wx. p>
