代码如下:
from tkinter import * from tkinter import messagebox class Application(Frame): def __init__(self, master=None): super().__init__(master) self.master = master self.pack() self.creatWidget() def creatWidget(self): """通过grid实现计算器的界面""" btnText = (("MC", "M+", "M-", "MR"), ("C", "±", "/", "*"), ("7", "8", "9", "-"), ("4", "5", "6", "+"), (1,2,3, "="), (0, ".")) Entry(self).grid(row=0,column=0,columnspan=4,pady=10) for rindex,r in enumerate(btnText): for cindex, c in enumerate(r): if c=="=": Button(self, text=c, width=2).\ grid(row=rindex + 1, column=cindex,rowspan=2, sticky=NSEW) elif c==0: Button(self, text=c, width=2).\ grid(row=rindex + 1, column=cindex, columnspan=2, sticky=NSEW) elif c==".": Button(self, text=c, width=2). \ grid(row=rindex + 1, column=cindex+1, sticky=NSEW) else: Button(self,text=c,width=2).\ grid(row=rindex+1,column=cindex,sticky=NSEW) if __name__ == '__main__': root = Tk() root.geometry("200x250+300+200") app = Application(master=root) root.mainloop()
