Question

Assume the earth’s continents drift about 1.25 centimeters per year. Write a Python program/script using a for-loop to display the total number of centimeters that the continents will have moved each year for the next 50 years.

a. What tasks need to be repeated (write in words)?

b. What is the start point of the loop and why?

c. What is the end point of the loop and why?

d. What is the start value for the initial drift and why?

e. Write the algorithm to output the following and provide the code in this file.

Output should look just like the following (will lose points for not following this format):

In year 1 the continents will have moved a total of 1.25 cm.

In year 2 the continents will have moved a total of 2.5 cm.

…

Answer 1

a.) The drift variable to track the total drift which is increased by 1.25 in each iteration.

The drift variable tracking the total drif should be printed in each iteration of the loop.

b.) The start point of the loop is 1 as we need to calculate total drift from now till 50 years.

c.) The end point of the loop is upto 51 , to perform 50 iterations so as to calculate total drift for the next 50 years.

d.) The start value for the initial drift is 0 as we need to calculate total drift from now till 50 years.

drift = 0
for i in range(1,51):
    drift = drift + 1.25
    print("In year",i,"the continents will have moved a total of",drift,"cm.")
    

OUTPUT:
