SAMPLE CODING QUESTIONS

Sample questions are for practice. The exam question will be different, but may borrow concepts from one or more samples.

Question 1:

Create a function that takes a number as a paramter and determines if the value is even or odd. The function should return True for even and False for odd.

Question 2:

Write a function that takes a string as a parameter. The function should return a new string that has all of the vowels removed.

Question 3:

Create a function that takes a list of strings as a paramter. The function should return a dictionary that contains each string and the number of times the string occurs in the list as key value pairs.

Sample input: ["hello", "world", "good", "hello"]
Sample output: { "hello":2, "world":1, "good":1}

Question 4:

Create a function that takes two parameters. The first parameter should be a number, the second a list of numbers. The function should modify the original list parameter such that it only contains numbers that are greater than or equal to the first parameter number.

Question 5:

Create a function that prints a rectangle to the screen using the * character. The function will take two parameters. The first parameter is the height of the rectange, and the second parameter is the width.

Example output for a 4, 5 rectangle.

Question 6:

Createa function that take a single string as a parameter. The function should return the string in reversed order. Try doing this with a loop. Try doing this again using only slicing.
