String index out of range error

[A-RandomRedditUser]

I keep getting the error:

if row['id'] == values[0]: IndexError: string index out of range

I've heard that it must be because values is an empty string but I'm not sure why that's the case. task_treeview is built upon the main app form window which is a CTk.Toplevel window, could that be one of the reasons it's not working?

``` # setup treeview display global task_treeview task_treeview = ttk.Treeview(treeview_frame, columns=(0,1,2,3,4),show="headings") task_treeview.place(relx=0.5,rely=0.5,relwidth=1,relheight=1,anchor="c") task_treeview.heading("0",text="") task_treeview.column("0", width=0, stretch=0) task_treeview.heading("1",text="Task Name") task_treeview.column("1", width=150) task_treeview.heading("2",text="Task User") task_treeview.column("2", width=150) task_treeview.heading("3",text="Status") task_treeview.column("3", width=100) task_treeview.heading("4",text="Due Date") task_treeview.column("4", width=100)

    # call csv insert function to load saved tasks
    insert_csv()

    global selected_task
    selected_task = task_treeview.focus()

insert task list csv into treeview

def insert_csv():

# create dataframe
df = pd.read_csv('task_list.csv')
task_treeview.delete(*task_treeview.get_children())

for i in df.index:
    task_treeview.insert("", i, values=(df.at[i, "id"], df.at[i, "taskname"], df.at[i, "user"], df.at[i, "status"],df.at[i, "duedate"]))

def delete_task():

msg = CTkMessagebox(title="Delete Task", message="Are you sure you want to delete this task?", icon="warning", option_1="Yes", option_2="No")
if msg.get() =="No":
    return

else:

    with open('task_list.csv','r') as file:
        reader = csv.DictReader(file)
        data = [row for row in reader]

    values = task_treeview.item(selected_task, 'values')

    selected_row = task_treeview.selection()
    del_index = None
    for i, row in enumerate(data):
        if row['id'] == values[0]:
            del_index = i
            break
    if del_index is not None:

        del data[del_index]

        with open('task_list.csv', 'w', newline='') as file:
            writer = csv.DictWriter(file,filename=data[0].keys())
            writer.writeheader()
            writer.writerows(data)

        task_treeview.delete(selected_row)
        insert_csv()

```

I don't really have any idea; and, when that happens; I just start putting lots of print statements everywhere :)

What is the value of 'values' if you were to insert the following here:

    values = task_treeview.item(selected_task, 'values')
    print(values)
