Assignment 3
Problems
-
Is it a triangle?
Write a program that accepts three numerical values and outputs a message indicating whether they could represent the lengths of the sides of a triangle or not. (Note: Not necessarily a right-angled triangle, just any triangle at all.)
A sample run might look like this,
================= Is it a triangle? ----------------- Enter your first value: 4 Enter the second value: 9 Enter the third value: 3 I'm afraid those three numbers could NOT represent the lengths of the sides of a triangle. -
Is it an Armstrong number?
An Armstrong number is an n digit number that is equal to the sum of its digits each raised to the n th power. For example 153 equals 1^3^+5^3^+3^3^, so it is an Armstrong number. Write a program that inputs a three-digit number, and outputs a message saying whether it is an Armstrong number or not.
A sample run might look like this,
========================== Is it an Armstrong number? -------------------------- Enter your number: 284 I'm afraid 284 is NOT an Armstrong number.
Hint You can pull apart a number to get its individual digits by dividing and modulo-ing by appropriate multiples of 10, e.g. num %10 will give you the 1s digit, i.e. the rightmost digit, and num/100 will give you the 100s digit, i.e. the leftmost digit.

Richter Scale
Write a program that inputs the Richter magnitude of an earthquake and outputs the corresponding description and typical effects according to the table* below.
----------------------- ----------------------- -----------------------
Richter\ Description Earthquake Effects
Magnitudes
Less than 2.0 Micro Microearthquakes, not
felt.
2.0-2.9 Minor Generally not felt, but
recorded.
3.0-3.9 Often felt, but rarely
causes damage.
4.0-4.9 Light Noticeable shaking of
indoor items, rattling
noises. Significant
damage unlikely.
5.0-5.9 Moderate Can cause major damage
to poorly constructed
buildings over small
regions. At most slight
damage to well-designed
buildings.
6.0-6.9 Strong Can be destructive in
areas up to about 160
kilometres (100 mi)
across in populated
areas.
7.0-7.9 Major Can cause serious
damage over larger
areas.
8.0-8.9 Great Can cause serious
damage in areas several
hundred miles across.
9.0-9.9 Devastating in areas
several thousand miles
across.
10.0+ Epic Never recorded; see
below for equivalent
seismic energy yield.
----------------------- ----------------------- -----------------------
A sample run might look like this,
======================
Earthquake Interpreter
----------------------
Enter the Richter magnitude of the earthquake: 4.4
Magnitude: 4.4
Description: Light.
Effects: Noticeable shaking of indoor items, rattling noises.
Significant damage unlikely.

Should I do Laundry?
Write a program that gets the users age, whether they have clean clothes, and whether they know how to do laundry. From that data the program should tell the user if they need to do laundry based on the flow chart below. I’d also like you to add one more question to the flow chart and think about how it might change the decision (something like smell or maybe accessibility issues). I’ve also included a sample run (with just the base criteria).
```
Should you do Laundry?
How old are you? 21 Do you have clean clothes (y or n)? n Do you know how to do laundry (y or n)? y Based on your answers it is time to do laundry! ```
Logistics
Use the following naming scheme for your program files:
aassignment#pproblem#name.py . So your solution
for problem 1 on this assignment will be named a3p1bob.py .
- based on one on the Wikipedia page on the Richter Scale.
