# Assignment:
    # Variable = Value (literal)
    # Values persist!
    # You can update (reassign values) but it doesn't modify variables
    # above it without another reassignment for other variables
    # that may have used the one that you changed.
    # I hope that made sense...
# next generation
generation = generation + 1 # This takes the previous value of # generation and adds 1
nbr_rabbits = nbr_rabbits * 2  # This takes the previous value
# (the previous assignment) of nbr_rabbits and
# multiplying it by two
# THIS IS REASSIGNMENT!!!!
