Exercise to practice loops in Python

Assignment 1

Lab Goal : This lab will focus on decision making and iteration [ looping ] while reviewing accessing numeric digits using mod and divide.

Lab Description : Write a program that will count up how many digits a number contains. You must use a loop and use / to reduce the number so that you can count all of the digits.

Sample Data :

234
10000
111

Assignment 2

Lab Goal : This lab will focus on decision making and iteration [ looping ] while reviewing accessing numeric digits using mod and divide.

Lab Description : Write a program that will sum all of a numbers digits. You must use % for this lab to access the right most digit of the number. You will use / to chop off the right most digit.

Sample Data

Assignment 3

Lab Description : Write a program that will average all of a numbers digits. You must use % for this lab to access the right most digit of the number. You will use / to chop off the right most digit.

Assignment 4

Lab Goal : This lab will focus on decision making and iteration [ looping ] while reviewing accessing numeric digits using mod and divide.

Lab Description : Write a program that will count all of a numbers even digits. You must use % for this lab to access the right most digit of the number. You will use / to chop off the right most digit. You will also need to use % mod to check for remainders to determine odd or even.

Assignment 5 Is Cool

Lab Goal : This lab will focus on loops, decision making, and methods.

Lab Description : Complete methods isCoolNum( n ) && countCoolNumbers( n ). isCoolNum( n) will determine if a number is a cool number. A cool number is any number that has a remainder of 1 when divided by 3,4,5, and 6. countCoolNumbers will count the number of cool numbers between 6 and the parameter passed in.

Sample Data
250
1250
2250
5500
9500
23500
32500

Sample Output :
4 cool numbers between 6 - 250
20 cool numbers between 6 - 1250
37 cool numbers between 6 - 2250
91 cool numbers between 6 - 5500
158 cool numbers between 6 - 9500
391 cool numbers between 6 - 23500
541 cool numbers between 6 - 32500

Assignment 6

Lab Goal : This lab was designed to teach you more about nested loops and conditions.
