Question

Project 5 - intro to python

Write a program in python that calculates the amount of money a person would earn over a period of time if his or her salary is one penny the first day, two pennies the second day, four pennies the third day, and continues to double each day. Output the amount earned each day .. and the total pay at the end.

The Algorithm (Plan) for your program would be:

Ask the user for the number of days to be worked

Verify that the amount entered is positive, and if not, continue to ask the fuser or an amount ..until a valid number is entered

For each day worked

      Calculate the pay

      Print out the pay

      Add the daily pay to the final total

Print out the final total of pennies

Print out the final total in dollars and cents form

SAMPLE OUTPUT would look like:

How many days will you work? -5

Please reenter .. days must be positive -10

Please reenter .. days must be positive 0

Please reenter .. days must be positive 16

Day 1 : 1 pennies

Day 2 : 2 pennies

Day 3 : 4 pennies

Day 4 : 8 pennies

Day 5 : 16 pennies

Day 6 : 32 pennies

Day 7 : 64 pennies

Day 8 : 128 pennies

Day 9 : 256 pennies

Day 10 : 512 pennies

Day 11 : 1024 pennies

Day 12 : 2048 pennies

Day 13 : 4096 pennies

Day 14 : 8192 pennies

Day 15 : 16384 pennies

Day 16 : 32768 pennies

Total amount earned 65535 pennies

or ..655 dollars and 35 cents

please make sure that each control structure is commented to indicate the task it is performing, and any code that is not obvious is briefly commented as well.

thank you

Answer 1

Python 3 code for above problem-

# taking input in "days" variable
days=input("How many days will you work? ");
#checking if "days" is positive and asking for another input
while(days<=0):
days=input("Please reenter .. days must be positive ");
# "total" to calculate the total amount earned.
total=0;
# iterating from 1 to days
for i in range(1,days+1):
# calculating the total amount
total+=pow(2,i-1);
# printing the amount earned each day
print("Day {0} : {1} pennies".format(i,pow(2,i-1)));
# printing the total amount in pennies
print("Total amount earned {0} pennies".format(total));
# printing the total amount in dollars and cents
print("or ..{0} dollars and {1} cents".format(total/100,total%100));
