# Comments beginning with "TODO" contain the tasks that you must
# complete in this interactive tutorial. Write your answers under each
# TODO. Use Find (Ctrl/Cmd + F) to keep track of them.
# 
# This is a Python file, not the interactive interpreter, so code won't
# run immediately when you write it. You also WON'T need the triple
# greater-than symbols (>>>) at the beginning of each line.
# 
# Just focus on writing Python to the best of your abilities! Once
# you're done, you'll have the chance to check your work in the next
# tutorial section, Running Python Code: https://bit.ly/2w3PbCX

# TODO 1: Write Monroe's favorite food in a string.

# TODO 2: Calculate the volume of a 7 x 7 x 5 cube using Python math
# operations.

# TODO 3: Pop the last item from this list, append 'filtration' to it,
# then change the second item to '1 LPS'. Don't change the original
# list.
#
# Hint: what number do Python lists start from? Check the lists section
# in the Writing Python Code tutorial if you're unsure.

# Don't change the original dict.

# TODO 5: Write a conditional statement that determines if both of
# the following conditions are met:
#       - Either a or b are True
#       - c is False
# If both conditions are met, set does_it_work to 'yes'. Otherwise,
# set it to 'no'.

# Don't try to figure these variables out! Just write a conditional
# that determines if the above conditions are met.

# TODO 6: Write a for loop that multiplies x by each integer from 1 to
# 30.
# 
# Hint: what does += do? Check the for loops section in the Writing
# Python Code tutorial if you're unsure. Try it with multiplication.

# TODO 7: Write a function called 'squared' that takes in a number and
# returns its square (to the power of 2). Then, call that function so
# that x is squared 6 times.
#
# Hint: Don't copy and paste the function 6 times!
