Basic Python Programming

3 test runs for each question

Use Control Statements (if and loops) that's it

7. Write a program using while loop with validation where user input wholesale prices to calculate retail prices. The markup is 2.5 times. Validation is to check if a value is out of range and display a message to let the user know that the value entered is an error. In this case the wholesale value cannot be less than zero.

Sample Run 1

>>>

Enter the items wholesale cost: -.50

ERROR: the cost cannot be negative

Enter the correct wholesale cost: .50

Retail price is $1.25

Do you have another item?

(Enter y for yes): n

Sample Run 2

Enter the items wholesale cost: .75

Retail price is $1.88

Do you have another item?

(Enter y for yes): Y

Enter the correct wholesale cost: .50

Retail price is $1.25

Do you have another item?

(Enter y for yes): n

8.Write a for loop using range() function to print Barzinger 5 times.

9.Write a program that uses a for loop to calculate the sum of numbers. The user will specify how many numbers to sum.

Sample Run

>>>

How many numbers do you want to add? 3

Enter number 1 : 25

Enter number 2 : 34

Enter number 3 : 33

The total is 92.0

10.Write a program using for loop to convert speeds from 60kph through 130kph (in 10 kph increments) to mph. The formula: mph = kph * conversion factor where conversion factor is 0.6214. (one test run only for this question)

Sample Run

>>>
