The below is key error message and i am not getting the solution for this

Error message:

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Users\97150\AppData\Local\Programs\Python\Python38\lib\tkinter\__init__.py", line 1883, in __call__
    return self.func(*args)
  File "abc.py", line 15, in GetValue
    e1.insert(0,select['id'])
KeyError: 'id'

this is full code which i updated

Answer 1

Since select is the result of listBox.set(row_id) , it is a dictionary of column/value pairs for the selected item. The keys are then the column names of the treeview listBox instead of the column names from the database table:

def GetValue(event):
    e1.delete(0, END)
    e2.delete(0, END)
    e3.delete(0, END)
    e4.delete(0, END)
    e5.delete(0, END)
    row_id = listBox.selection()[0]
    select = listBox.set(row_id)
    e1.insert(0, select['Criminal id'])
    e2.insert(0, select['Criminal Name'])
    e3.insert(0, select['Criminal Father-Name'])
    e4.insert(0, select['Criminal Type'])
    e5.insert(0, select['Criminal Occupation'])
