A tkinter GUI with a grid of widgets

See Label, Entry, OptionMenu, Button, Text, StringVar, and the other things.

The widgets are positioned in a 3 × 3 grid. The rows of the grid are numbered from top to bottom, starting at 0. The columns of the grid are numbered from left to right, starting at 0. The Text widget that occupies row 2 spans all three columns. The last column of row 0 is empty.

Label	Label
Entry	OptionMenu	Button
Text

The "1.0" in lines 114, 120, 124, 131, 144 means the first character on the first line of the Text widget. The 1 and 0 are the line and column numbers. See Text widget indices.

Things to try

1. Add the four avenues in Alphabet City.
2. Change the above lines 162–168 from

   avenueNames = []   #Start with an empty list.
   for avenue in avenues:
       avenueNames.append(avenue[0])
   

   to the following list comprehension.

   #Create a new list named avenueNames that has the same number of elements
   #as the existing list avenues.
   
   avenueNames = [avenue[0] for avenue in avenues]
   



3. What happens if you remove the asterisk from line 172? See Calls.


4. Does the script always output the lower of the two streets between which the address lies? If so, change the script to output both streets.

   350 Fifth Avenue is between 33rd and 34th Streets.
