萌新制作,不满勿喷
效果图在代码下方
代码:
- from tkinter import *
- root = Tk()
- root.wm_minsize(400, 160) # 设置窗口大小
- ShowNumEntry = Entry(root, width=8, justify="right", font=12)
- ShowNumEntry.grid(row=0, column=5)
- def getInputValue(ShowNumEntry, Value):
- ShowNumEntry.insert(END, Value)
- def GetResult():
- result = eval(ShowNumEntry.get())
- getClean()
- ShowNumEntry.insert(0, str(result))
- def num_choice(num):
- if num == 1:
- getInputValue(ShowNumEntry,"1")
- elif num==2:
- getInputValue(ShowNumEntry, "2")
- elif num==3:
- getInputValue(ShowNumEntry, "3")
- elif num==4:

- getInputValue(ShowNumEntry, "5")
- elif num==6:
- getInputValue(ShowNumEntry, "6")
- elif num==7:
- getInputValue(ShowNumEntry, "7")
- elif num==8:
- getInputValue(ShowNumEntry, "8")
- elif num==9:
- getInputValue(ShowNumEntry, "9")
- elif num==0:
- getInputValue(ShowNumEntry, "0")
- def operator_choice(oper):
- if oper == "+":
- getInputValue(ShowNumEntry,"+")
- elif oper=="-":
- getInputValue(ShowNumEntry, "-")
- elif oper=="*":
- getInputValue(ShowNumEntry, "*")
- elif oper=="/":
- getInputValue(ShowNumEntry, "/")
- elif oper == ".":
- getInputValue(ShowNumEntry, ".")
