Project: unit converter

Python · Unit 4: Functions

You're going to build a temperature converter out of small functions.

Each one does a single conversion and hands back the result with return.

def miles_to_feet(mi):
    return mi * 5280

print(miles_to_feet(3))

Prints

Exercises in this lesson

You do them in the app, which checks them on the spot and explains why.

1. Write the code
Write to_fahrenheit(c), which takes degrees Celsius and hands back the Fahrenheit. The formula is multiply by 9, divide by 5 and add 32.
2. Write the code
Write convert(temp, to="F"). If to is "F", hand back the degrees in Fahrenheit; if it is "C", in Celsius. Use the two functions that are already there.
