Question

如何传递我的 website_name ，这是一个网址，例如https://www.google.com/;从＆＃34; def proceed3（）＆＃34; 到＆＃34; def openChrome（）＆＃34; ？有什么建议吗？

from Tkinter import *


def proceed3():
    popup = Toplevel()
    popup.geometry("350x175+350+180")
    popup.resizable(width=False, height=False)
    instruction = Label(popup, text="Enter the URL and pressGO!").pack()
    website_name = Entry(popup, width=50).pack(pady=5)
    goButton = Button(popup, text="GO!", command=openChrome)
    goButton.pack(pady=5)


def openChrome():
    openWebsite = website_name.get()
    os.system(r"start chrome " + openWebsite)


windows = Tk()

windows.geometry("200x200+375+280")
windows.resizable(width=False, height=False)



submitButton = Button(windows, text='OpenChrome', command=proceed3)
submitButton.pack(pady=5)

windows.mainloop()

添加 return website_name到您的proceed3（）函数的末尾

在OpenChrome（）函数中添加一个参数website_name。

def proceed3():
    popup = Toplevel()
    popup.geometry("350x175+350+180")
    popup.resizable(width=False, height=False)
    instruction = Label(popup, text="Enter the URL and pressGO!").pack()
    website_name = Entry(popup, width=50).pack(pady=5)
    goButton = Button(popup, text="GO!", command=openChrome)
    goButton.pack(pady=5)
    return website_name


def openChrome(website_name):
    os.system(r"start chrome " + website_name)

我建议阅读有关如何在python中使用函数的this tutorial，因为这对于进一步完善编程工作至关重要。

求助：python2.7：处理这个功能;想从＆＃34; def proceed3（）＆＃34;获得输入to＆＃34; def openChrome（）＆＃34;
