Question

您好，我正在制作一个以mysql为后端的python tkinter程序，并且我计划进行此程序的开发，在其中要键入预定总线的详细信息，并且必须在sql数据库中沿着总线号进行验证但是我遇到了问题，该程序无法提供所需的输出

我搜索了网和手册，但没有希望

import tkinter as tk
from tkinter import messagebox
import os
from mysql.connector import Error
def payment():
    os.system('payment.py')

def chk1():
    no = E5.get()

    chk2(no)
def chk2(a):
    import mysql.connector    
    try:
        dbcrd = 'db.WDC'
        with open(dbcrd) as f:
            data = f.readlines() 
            uname = data[0].rstrip() 
            pword = data[1].rstrip()
            lchst = data[2].rstrip()

        mySQLConnection = mysql.connector.connect(host = lchst,user = uname,passwd = pword,database = 'booking',raw = True)

        cursor = mySQLConnection.cursor()
        sql_select_query = """select COUNT(*) from bus where B_No = %s"""
        a = cursor.execute(sql_select_query,(a,))
        exn1 = cursor.fetchall()
        print (a)
        for i in exn1:
            print(i)

        if exn1 != 1:
            messagebox.showinfo('Error','The Given Bus number was not found')
        else:
            payment()
       #c = cursor.fetchone()
       #print (c)

    except Error as e :
        print (e)



global E5
D1=tk.Tk()
D1.geometry('350x200')

L1 = tk.Label(D1,text='Enter Passenger Name:')
E1 = tk.Entry(D1)
L2 = tk.Label(D1,text='Enter Gender')
E2 = tk.Entry(D1)
L3 = tk.Label(D1,text='Number of seats')
E3 = tk.Entry(D1)
L4 = tk.Label(D1,text='Date:')
E4 = tk.Entry(D1) 
L5 = tk.Label(D1,text='Bus Number')
E5 = tk.Entry(D1)
L6 = tk.Label(D1,text='Phone Number:')
E6 = tk.Entry(D1)
L7 = tk.Label(D1,text='Aadhar')
E7 = tk.Entry(D1)

L1.grid(column = 1,row= 1)
L2.grid(column = 1,row= 2)
L3.grid(column = 1,row= 3)
L4.grid(column = 1,row= 4)
L5.grid(column = 1,row= 5)
L6.grid(column= 1,row= 6)
L7.grid(column= 1,row= 7)

E1.grid(column = 2,row= 1)
E2.grid(column = 2,row= 2)
E3.grid(column = 2,row= 3)
E4.grid(column = 2,row= 4)
E5.grid(column = 2,row= 5)
E6.grid(column = 2,row= 6)
E7.grid(column = 2,row= 7)

B2=tk.Button(D1,text='Next',width=12,height=1,command =chk1)

B2.grid(column=2,row=8 )
D1.mainloop()

错误是它没有运行定义付款，而是说没有找到总线号，尽管sql中的数据是正确的我希望程序能够完美运行，并提供定义付款作为程序输出的结果
