我一直致力于一个小型项目,其中计算器必须嵌入盒子中。我正在使用 Tkinter 。
我的代码:
import tkinter
top = tkinter.Tk()
def add(x, y):
return x + y
def subtract(x, y):
return x - y
def multiply(x, y):
return x * y
def divide(x, y):
return x / y
print("Select operation.")
print("1.Add")
print("2.Subtract")
print("3.Multiply")
print("4.Divide")
choice = input("Enter choice(1/2/3/4):")
num1 = int(input("Enter first number: "))
num2 = int(input("Enter second number: "))
if choice == '1':
print(num1,"+",num2,"=", add(num1,num2))
elif choice == '2':
print(num1,"-",num2,"=", subtract(num1,num2))
elif choice == '3':
print(num1,"*",num2,"=", multiply(num1,num2))
elif choice == '4':
print(num1,"/",num2,"=", divide(num1,num2))
else:
print("Invalid input")
top.mainloop()
问题是计算器没有在包装盒内打开。我得到以下输出:
Select operation.
1.Add
2.Subtract
3.Multiply
4.Divide
Enter choice(1/2/3/4): 3
Enter first number: 15
Enter second number: 14
15 * 14 = 210
我需要的是在盒子里面显示它。
答案 0 :(得分:0)
你还没有创建一个“盒子”,所以在你做之前显示一个东西会很困难。
该行:
top = tkinter.Tk()
为Tkinter
GUI创建根窗口。要在其中打印内容,您需要添加可在根窗口中写入的窗口小部件(GUI元素)。这里一个很好的选择是Text
小部件:
import Tkinter as tk
root = tk.Tk()
my_text = tk.Text(root)
my_text.pack()
现在要打印到文本框而不是终端,您可以用Text.insert
方法替换打印语句。
my_text.insert(tk.END,"Hello, this is some text\n")
my_text.insert(tk.END,"This is some other text\n")
my_text.insert("0.0","This is some text starting at row 0 and column 0\n")
my_text.insert(tk.CURRENT,"This is even more text, this time starting from the current cursor position\n")
