Question

我有一个模块，我正在调用一个函数来返回凭据数据列表。该代码在普通的python3中工作，但是在tkinter中运行时，直到我关闭tkinter对话框之后，它才能获取值，然后按正常方式处理该函数的其余部分-除非我的程序已关闭。我已将所有内容追溯到dbconnect.py的返回。任何指针将不胜感激。谢谢！编辑：添加了login（）函数。功能内的注释功能。从不实际退出login（）。最后的输出来自子功能userinfo（）。似乎停在那里，直到原始调用对话框关闭，然后成功完成主程序中的最后一个调用函数。

本地脚本调用：

import dbconnect

array = dbconnect.getcredentials()

dbconnect.py模块 dbconnect具有相关的功能，这些功能可以共同使用户登录并返回列表。

def getcredentials(): # call from other scripts for connection setup.
    credentials = []
    for item in sys.argv:
        credentials.append(item.strip("[,]"))
    credentials.pop(0)

    print("getcredentials(): items in argv after pop: ", credentials)

    if credentials:
        return(credentials)
    else:
        print("credentials not inialized!.def login():
# Create logwin window
logwin = Toplevel()
logwin.title("Log In")

# Called by login() GUI/bsubmit - returns credentials from log in GUI
def userinfo():
    global array
    # array = []
    sname=serventry.get()
    lname=lnentry.get()
    pname=passentry.get()
    array = [sname, lname, pname]
    logwin.destroy()
    print("userinfo() = ", array)
    return array

    sname=serventry.get()
    lname=lnentry.get()
    pname=passentry.get()
    array = [sname, lname, pname]
    logwin.destroy()
    print("userinfoalt() = ", array)
    return array


# Create GUI

servlabel.grid(row=0, column=0)

bsubmit.grid(row=4, column=1, columnspan=2)

logwin.bind('<Return>', userinfoalt) # binds alternate credentials function to the return key.
