# ### Lecture 3
# Answer each number in a separate cell
# 
# Rename this notebook with your last name, first initial and the (2 digit) lecture number. 
#     
#     ex. Cych_B_03
#     
# Turn in this notebook on Canvas. 

# ### Oceans and Continents
# 1.  Conceptual 
#      - Give an example of when you would  use a set
#      - Give an example of when you would use a tuple
#      -  Give an example of when you would use range( ) 
# 2.  Lists
#      -  Create an empty list called _oceans_
#      -  append all the oceans to the list  
#      -  print the ocean at **index** 3 in the list  
#      -  print the last element of your list. 
#      -  make a shallow copy of _oceans_ called _seas_ and a deep copy of _oceans_ called  _big_water_. Try to modify the copies. Verify that the shallow copy refers to the same underlying object while the deep copy makes an independent object.  
#      -  Apply the method **.sort()** to one of your copies and then print the copy
# 3. range( )
#      -  Use the function **range( )** to create a list with a  “range” of numbers from 0 up to (but not including) 100, increment by any number (less than 100) and print the results.
# 4. Tuples
#      -  Create a tuple called _continents_ with the continents as elements.
#      -  Attempt to change the second **element** (not index) in place (this should throw and error). 
#      -  print out the third **element** (not index)  in the tuple
# 5. Sets
#      -  create a set from the _oceans_ list you created earlier.
#      -  print out the set of oceans
