Single Digit
Write the function single_digit(integer), that returns True if the parameter integer is a positive, single digit integer and False otherwise.
Example
| Test Code | Output |
|---|---|
| print(single_digit(0)) | True |
| print(single_digit(9)) | True |
| print(single_digit(10)) | False |
| print(single_digit(-1)) | False |
Rock, Paper, Scissors
Write the function rps_string(integer) that returns the string ‘rock’, ‘paper’, ‘scissors’, or ‘error’ depending on the value of the specified integer. If integer is 0, the function should return ‘rock’. If integer is 1, the function should return ‘paper’. If integer is 2, the function should return ‘scissors’. If integer is not 0, 1, or 2, the function should return ‘error’.
Example
| Test Code | Output |
|---|---|
| print(rps_string(0)) | rock |
| print(rps_string(1)) | paper |
| print(rps_string(2)) | scissors |
| print(rps_string(3)) | error |
| print(rps_string(-1)) | error |
Leap Years
One of the most confusing aspects of validating dates is accounting for the number of leap years in that period. Every year, there is roughly an extra 1/4 day. To account for this, almost every 4 years we add an additional day to the month of Februray. The rules for this are straight-forward, but the reasoning and implementation of them is sometimes confusing.
A leap year occurs almost every 4 years. All leap years are divisible by 4, but not all years divisible by 4 are leap years. A year is a leap year if it is divisible by 4, unless it is divisible by 100 and not divisible by 400.
Details
Write the function is_leap(year). The function should return True if the year parameter is a leap year, and False otherwise.
Example
| Test Code | Output |
|---|---|
| print(is_leap(1900)) | False |
| print(is_leap(2000)) | True |
| print(is_leap(1996)) | True |
| print(is_leap(2015)) | False |
| print(is_leap(2016)) | True |
