Assignment 2: Python Functions and Classes¶

Part I: Writing Functions¶

1. Write a function to convert temperature from kelvin to celsius, and another function to covert from celsius to kelvin¶

In [ ]:

In [ ]:

2. Write a function to convert temperature to fahrenheit¶

Include an optional keyword argument to specify whether the input is in celcius or kelvin. Call your previously defined functions if necessary.

In [ ]:

3. Check that the outputs are sensible¶

by trying a few examples

4. Now write a function that converts from farenheit¶

and uses a keyword argument to specify whether you want the output in celcius or kelvin

In [ ]:

5. Write a function that takes two arguments (feet and inches) and returns height in meters¶

Verify it gives sensible answers

6. Write a function takes one argument (height in meters) and returns two arguments (feet and inches)¶

(Consult the tutorial on numbers if you are stuck on how to implement this.)

7. Verify that the "round trip" conversion from and back to meters is consistent¶

Check for 3 different values of height in meters

Part IV: Classes¶

Write a class that represents a Location. The constructor class should accept the arguments name, latitude, and longitude.

Check if the latitude is between -90 to 90, and the longitude is between -180 and 180. Raise ValueError if not.

You should implement a method to calculate its relative location to our ENR building:

• relative_loc_from_ENR: The lat/lon of ENR buidling is: 40.476˚N, 74.43˚W. Print out if the location is 1) to the north or south or ENR; (2)to the east or west of ENR.
