LAB

Estimated time

10-15 minutes
Level of difficulty

Easy
Objectives

Familiarize the student with:

projecting and writing parameterized functions;
utilizing the return statement;
testing the functions.

Scenario

Your task is to write and test a function which takes one argument (a year) and returns True if the year is a leap year, or False otherwise.

The seed of the function is already sown in the skeleton code in the editor.

Note: we've also prepared a short testing code, which you can use to test your function.

The code uses two lists - one with the test data, and the other containing the expected results. The code will tell you if any of your results are invalid.

def is_year_leap(year):
#
# put your code here
#

test_data = [1900, 2000, 2016, 1987]
test_results = [False, True, True, False]
for i in range(len(test_data)):
	yr = test_data[i]
	print(yr,"->",end="")
	result = is_year_leap(yr)
	if result == test_results[i]:
		print("OK")
	else:
		print("Failed")
