guis and data

The Save button on the interface is going to call a function called
save_data(). The function will append the data from the GUI
to the end of the deliveries.txt file formatted like this:

Depot:
Seattle, WA
Description:
Books
Address:
1 Main Street
Anytown
WA

Then it will need to clear the fields on the form ready for the next record to be entered. The function will
have to appear in the program before the GUI code. You were to write the code for the function here:
Your code may look a Append the text to the end of the file,
little different. just as you did when we wrote the POS

def save_data(): programs for the Health Club.
fileD = open(“deliveries.txt", “a")

get() returns the fileD.write(“Depot:\n")
contents of an Entry fileD.write(“%s\n" % depot.get())
field.
fileD.write(“Description:\n")
fileD.write(“%s\n" % description.get())
get(“1.0", END)
returns the fileD.write(“Address:\n")
contents of a T ext fileD.write(“%s\n" % address.get(“1.0", END))
field.
depot.delete(0, END)
description.delete(0, END)
Don't forget to clear
the fields after saving address.delete(“1.0", END)
the data.
This means “1st row, 0th column." Remember
that rows start at 1 and columns from 0.
