Question

Hi I am using python and I keep getting this error with my code. Traceback (most recent call last):
['1']
Traceback (most recent call last):
File "/Users/isabellawelch/Python ish/shuffle.py", line 86, in <module>
emp = Employee(emp_data[0], emp_data[1], emp_data[2], emp_data[3], emp_data[4])
IndexError: list index out of range

What does it mean and how do i fix it??

from tkinter import Tk, Label, Button, Entry, END

As you can see only one data ['1'] that printed for emp_data but in here

Employee(emp_data[0], emp_data[1], emp_data[2], emp_data[3], emp_data[4])

required atleast five data to work on that's why you getting index error,

and can you check your file /Users/isabellawelch/Downloads/data.txt

that have sufficient entry it should have min 5 data seprated by comma.

lets say just for example if file have 1,2,3,4,5 have date then emp_data will have ['1','2','3','4','5'] then Index Error will not occur

please try if not then comment will help you further.
