+Modified calcGUI
+This example helps show how the tkinter library works in Python.
+Run it and press the 1 key on your keyboard. Why does "dominic" appear in the entry bar?
+Why does one key have "DT" on it? When you click it, why does it make "Thomas" show in the entry bar?
+Why is the font in the entry bar now fancy?
+How would we add more buttons?

+# <font size="5" color="#00A0B2"  face="verdana"> <B>Student will be able to</B></font>
+# - use Python 3 in Jupyter notebooks
+# - write working code using `print()` and `#` comments  
+# - write working code using `type()` and variables
+# - combine strings using string addition (+)
+# - add numbers in code (+)
+# - troubleshoot errors
+# - create character art  
+# 
+# # &nbsp;
+# >**note:** the **[ ]** indicates student has a task to complete  
+#   
+# >**reminder:** to run code and save changes: student should upload or clone a copy of notebooks 
+# 
+# #### notebook use
+# - [ ] insert a **code cell** below   
+# - [ ] enter the following Python code, including the comment: 
+# ```python 
+# # [ ] print 'Hello!' and remember to save notebook!
+# print('Hello!')
+# ```
+# Then run the code - the output should be:  
+# `Hello!`
+
+# %%
+# [ ] print 'Hello' and remember to save notebook!
+print('Hello!')
+
+# %% [markdown]
+# #### run the cell below   
+# - [ ] use **Ctrl + Enter**  
+# - [ ] use **Shift + Enter**    
+
+# %%
+print('watch for the cat')
+
+# %% [markdown]
+# #### Christina's Notebook editing
+# - [ ] Edit **this** notebook Markdown cell replacing the word "Student's" above with your name
+# - [ ] Run the cell to display the formatted text
+# - [ ] Run any 'markdown' cells that are in edit mode, so they are easier to read
+
+# %%
+#### [ ] convert \*this\* cell from markdown to a code cell, then run it  
+print('Run as a code cell')
+
+
+# %% [markdown]
+# ##  # comments
+# create a code comment that identifies this notebook, containing your name and the date
+
+# %%
+# Christina Timokhin 
+# 02/05/2022
+
+# %% [markdown]
+# #### use print() to 
+# - [ ] print [**your_name**]
+# - [ ] print **is using python!**
+
+# %%
+# [ ] print your name
+print("Christina Timokhin")
+# [ ] print "is using Python"

+
+
+# %% [markdown]
+# Output above should be:  
+# `Your Name  
+# is using Python!`  
+
+# %% [markdown]
+# #### use variables in print()
+# - [ ] create a variable **your_name** and assign it a string containing your name
+# - [ ] print **your_name**
+
+# %%
+# [ ] create a variable your_name and assign it a sting containing your name
+christina_timokhin = "Christina Timokhin"

+# %% [markdown]
+# #### create more string variables
+# - **[ ]** create variables as directed below

+# #### use string addition
+# - **[ ]**  print the above string variables (favorite_song, shoe_size, lucky_number) combined with a description by using **string addition**
+# >for example favorite_song displayed as:  
+# `favorite song is happy birthday`
+
+# %%

+# %%
+
+
+# %% [markdown]
+# ##### more string addition
+# - **[ ]** make a single string (sentence) in a variable called favorite_lucky_shoe using **string addition** with favorite_song, shoe_size, lucky_number variables and other strings as needed 
+# - **[ ]** print the value of the favorite_lucky_shoe variable string
+# > sample output:  
+# `For singing happy birthday 8.5 times, you will be fined $25`
