问题
Please Help me. I'm running a simple python program that will display the data from mySQL database in a tkinter form...
from Tkinter import *
import MySQLdb
def button_click():
root.destroy()
root = Tk()
root.geometry("600x500+10+10")
root.title("Ariba")
myContainer = Frame(root)
myContainer.pack(side=TOP, expand=YES, fill=BOTH)
db = MySQLdb.connect ("localhost","root","","chocoholics")
s = "Select * from member"
cursor = db.cursor()
cursor.execute(s)
rows = cursor.fetchall()
x = rows[1][1] + " " + rows[1][2]
myLabel1 = Label(myContainer, text = x)
y = rows[2][1] + " " + rows[2][2]
myLabel2 = Label(myContainer, text = y)
btn = Button(myContainer, text = "Quit", command=button_click, height=1, width=6)
myLabel1.pack(side=TOP, expand=NO, fill=BOTH)
myLabel2.pack(side=TOP, expand=NO, fill=BOTH)
btn.pack(side=TOP, expand=YES, fill=NONE)
Thats the whole program....
The error was
x = rows[1][1] + " " + rows[1][2]
IndexError: tuple index out of range
y = rows[2][1] + " " + rows[2][2]
IndexError: tuple index out of range
Can anyone help me??? im new in python.
Thank you so much....
回答1:
Probably one of the indexes is wrong, either the inner one or the outer one.
I suspect you mean to say [0] where you say [1] and [1] where you say [2]. Indexes are 0-based in Python.
回答2:
This is because your row variable/tuple does not contain any value for that index. You can try printing the whole list like print(row) and check how many indexes there exists.
