remove widgets from grid in tkinter
Question: I have a grid in a tkinter frame which displays query results. It has a date
field that is changed manually and then date is used as a parameter on the
query for those results. every time the date is changed, obviously the results
change, giving a different amount of rows. The problem is that if you get less
rows the second time you do it, you will still have results from the first
query underneath those and will be very confusing.

My question is, how can i remove all rows from the frame that have a row
number greater than 6 (regardless of what's in it)?

By the way, I'm running Python 3.3.3. Thanks in advance!


Answer: Calling the method `grid_forget` on the widget will remove it from the window
- this example uses the call `grid_slaves` on the parent to findout all
widgets mapped to the grid, and then the `grid_info` call to learn about each
widget's position:

    
    
    >>> import tkinter
    # create: 
    >>> a = tkinter.Tk()
    >>> for i in range(10):
    ...    label = tkinter.Label(a, text=str(i))
    ...    label.grid(column=0, row=i)
    # remove from screen:
    >>> for label in a.grid_slaves():
    ...    if int(label.grid_info()["row"]) > 6:
    ...       label.grid_forget()
