""" Purpose: simple simulation of rabbit growth over four generations
"""

# Get simulation info

reply1 = input( "How many rabbits: " ) # take whatever number is typed
reply2 = input( "Growth rate per generation: " ) # hands back a string of that value

starting_number_of_rabbits = int( reply1 ) # int() only works with ONE input
generation_growth_rate     = int( reply2 ) # this is a GOTCHA
# we could say reply1 = int( reply1 ) and that would work too
# we'll be switching from strings and integers all the time so make sure
# this makes sense now

# t1 = type(starting_number_of_rabbits)
# print(starting_number_of_rabbits, t1)
# python knows what kind of data is in each variable
# if you want to do math with a string, you have to change it to a number
# using int() or float()

# starting_number_of_rabbits will not change
# generation_growth_rate is also constant

# the int() function takes whatever ONE input is given to it and converts it
# to an integer number as best it can
# int( "five" ) will not return 5, int( '5' ) will return 5
# float( '5.6' ) = 5.6

# an integer string looks like this '6'

# the int() function allows you to change data types from strings to numbers
# remember our arithmetic functions will only work with numbers

# don't call functions inside functions, stay simple :)

# Next generation (second)

# each rabbit produces that many new rabbits
# we are updating the value of the variable
# python does not care if a variable is on both sides of an assignment statement
# i'm going to compute the right side and store it in the left
# computation of right side is independent of target (left side)
# erase the connotation of = and equals when you enter CS
generation = generation + 1
# remember this is assignment - take the current value and add 1

# PLEASE DO NOT BRING COVID HERE
# watch the videos, attend office hours, we'll help you

# run all the test cases given, as different test cases test different aspects
# pay attention - read the problem fully and run all the test cases

# tips to avoid confusing your code
# use descriptive variable names!
# walk through your code without running it, check that each variable is correct
