# In your own words, write a sentence saying that you have read every word 
# of the course syllabus and that you fully understand it:
#
#
#
#
#


# For the functions below, erase the "return 42" line and write the
# appropriate piece of code instead.

# Given an integer or float degreesInFahrenheit, convert it to corresponding
# degrees in celsius.
def convertToCelsius(degreesInFahrenheit):
    return 42


# Given an integer or float degreesInCelsius, convert it to corresponding
# degrees in fahrenheit.
def convertToFahrenheit(degreesInCelsius):
    return 42


# Given an integer n, return the absolute value of that integer. 
def absoluteValue(n):
    return 42


# Given an integer n, return True if n is even and return False otherwise. 
# Hint: use the % operator.
def isEven(n):
    return 42


# If you have written the functions correctly, you should not get any errors
# when you run this file, i.e., you should pass all the tests.
