If-Else在函式下無法在Tkinter中作業，請解決這個問題：-有解無憂

from tkinter import *
import tkinter.messagebox as tmsg

root = Tk()


def myaccount():
    Label(root, text="\n\nEnter Your Account Number : ").pack(anchor="nw")
    global en
    en = Entry(font=" helectiva 11")
    en.pack(anchor="nw")

    def detail():
        if en=="91xxxxxxxx":
                Label(text="Hello").pack()
    b = Button(root, text="View my Account Details",borderwidth=10,command=detail)
    b.pack(anchor="nw")

txt = StringVar()
txt.set("——Welcome To Banking System Application——")
txt1 = StringVar()
txt1.set("*****************************************************")
txt2 = StringVar()
txt2.set("\n\nChoose from the Options :")
txt3 = StringVar()
txt3.set("—————————————————————————————")


Label(root, textvariable = txt).pack()
Label(root, textvariable = txt1).pack()
Label(root, textvariable = txt2).pack()
Label(root, textvariable= txt3).pack()
Button(root, text="View My Account",borderwidth=10,command=myaccount).pack(anchor="nw",ipadx=32)
Button(root, text="New Account",borderwidth=10).pack(anchor="nw",ipadx=72)
Button(root, text="Make a Transactiom",borderwidth=10).pack(anchor="nw")
Button(root, text="Exit",borderwidth=10,command=quit).pack(anchor="nw",ipadx=170)

root.mainloop()

請幫我解決一下這個。if我的detail函式中的子句不起作用。我試圖連續解決它 5 個小時，但找不到正確的原因。但是如果你找到原因請給出答案，我會非常感謝那個人。

uj5u.com熱心網友回復：

條目物件不能是字串。相反，您必須獲取條目物件內的文本：

if en.get() == '91xxxxxxxx'
    Label(text="Hello").pack()

最終代碼：

from tkinter import *
import tkinter.messagebox as tmsg

root = Tk()


def myaccount():
    Label(root, text="\n\nEnter Your Account Number : ").pack(anchor="nw")
    global en
    en = Entry(font=" helectiva 11")
    en.pack(anchor="nw")

    def detail():
        if en.get() == '91xxxxxxxx'
            Label(text="Hello").pack()
    b = Button(root, text="View my Account Details",borderwidth=10,command=detail)
    b.pack(anchor="nw")

txt = StringVar()
txt.set("——Welcome To Banking System Application——")
txt1 = StringVar()
txt1.set("*****************************************************")
txt2 = StringVar()
txt2.set("\n\nChoose from the Options :")
txt3 = StringVar()
txt3.set("—————————————————————————————")


Label(root, textvariable = txt).pack()
Label(root, textvariable = txt1).pack()
Label(root, textvariable = txt2).pack()
Label(root, textvariable= txt3).pack()
Button(root, text="View My Account",borderwidth=10,command=myaccount).pack(anchor="nw",ipadx=32)
Button(root, text="New Account",borderwidth=10).pack(anchor="nw",ipadx=72)
Button(root, text="Make a Transactiom",borderwidth=10).pack(anchor="nw")
Button(root, text="Exit",borderwidth=10,command=quit).pack(anchor="nw",ipadx=170)

root.mainloop()
