# This is a collection of my codes, generated by myself for learning Python
# This challenge is about understanding tkinter and making GUI in Python.

# START OF CHALLENGE (TIM BUCHALKA, JEAN-PAUL ROBERTS)
#
# Write a GUI program to create a simple calculator
# layout that looks like the screenshot.
#
# Try to be as Pythonic as possible - it's ok if you
# end up writing repeated Button and Grid statements,
# but consider using lists and a for loop.
#
# There is no need to store the buttons in variables.
#
# As an optional extra, refer to the documentation to
# work out how to use minsize() to prevent your window
# from being shrunk so that the widgets vanish from view.
#
# Hint: You may want to use the widgets .winfo_height() and
# winfo_width() methods, in which case you should know that
# they will not return the correct results unless the window
# has been forced to draw the widgets by calling its .update()
# method first.
#
# If you are using Windows you will probably find that the
# width is already constrained and can't be resized too small.
# The height will still need to be constrained, though.
