小编Eri*_*les的帖子

好的,所以我是C#的新手,但已经学到了一点.但我有一个问题,如何用"*"替换键入控制台的字符或者只是完全隐藏它们？

        var pw = "eric123";
        Console.WriteLine("Password: ");
        var value = Console.ReadLine();
        if (value == pw)
        {
            Console.WriteLine("Permitted, Play online? (Y/N)?");
            var getGameOnlineStatus = Console.ReadLine();

            //Rest Of the Code is just for me :)

任何帮助,将不胜感激!

好的，所以我有问题。我正在尝试制作一个 GUI 十六进制转换器，但我一直收到同样的错误。我对 Tkinter 没有经验，所以有人可以帮助我吗？这是代码：

from Tkinter import *

def getNum():
   hex1 = e1.get()
   dec1 = int(hex1, 16)
   ol.configure(text=dec1)



root = Tk()

introLabel = Label(root, text='Input Hex Code: ').pack()

e1 = Entry(root)
e1.pack()
e1.focus_set()

inputButton = Button(root, text='Submit Hex Code', command=getNum).pack()

ol = Label(root, text='Hex Code will appear here.').pack()



root.mainloop()

我不断收到此错误：

Exception in Tkinter callback
