Checkpoint B For Checkpoint B you will extend Checkpoint A to do the following: 1. Prompts the user for an additional parameter: the bound on the timescale $n$ of the simulation If a user inputs a negative timescale, the program should immediately print an error message and exit. 2. The program will calculate , for every time in and output these populations at each step • If the population grows negative, treat it as population that has become zero. Hint: your program will need a for-loop. Complete this checkpoint after we have introduced for-loops in class. Sample Output Sample input/output behavior for the checkpoint are provided below. Your program's spacing, spelling, capitalization, and punctuation will need to match the sample output EXACTLY for this project.

Add a main function to the following python code and organize the program using mainline logic.  def resistance(i,e):    return e/i #Compute the total resistance as per the given formula    def parallel_resistance(r1,r2,r3):    return 1.0/((1.0/r1)+(1.0/r2)+(1.0/r3)) #Compute the series resistance def series_resistance(r1,r2,r3):    return r1+r2+r3 #Read the voltage e1=float(input('Voltage 1 : '))e2=float(input('Voltage 2 : '))e3=float(input('Voltage 3 : ')) #Read the currenti1=float(input('Current 1 : '))i2=float(input('Current 2 : '))i3=float(input('Current 3 : ')) #Compute the resistance r1=resistance(i1,e1)r2=resistance(i2,e2)r3=resistance(i3,e3)     #Compute the resistance in parallel Circuitrp=parallel_resistance(r1,r2,r3) #Compute the resistance in series Circuitrs=series_resistance(r1,r2,r3) #Display the result  print('Resistance in Parallel Circuit : {0:.2f}'.format(rp))print('Resistance in Series  Circuit : {0:.2f}'.format(rs))

PLEASE MATLAB NOT PYTHON OR OTHERS

Please give some examples on how to use the following in Python. Please do example codes Bool, int, floats Range List slicing operations
