These exercises were designed to provide additional coding practice and allow learners to prepare for a proctored practical exam where they are asked to write code to solve simple problems.

Learners will copy/paste these exercises into a .py file and write answers below each commented instruction.

## Objective 1

The learner integrates Python elements including data types, constants, variables, operators, and expressions to create programming solutions.

**# Task 1**

# declare 3 variables with one assignment statement and assign each one an integer value

**# Task 2**

# convert each of your previous variables to float objects

**# Task 3**

# convert each of your previous variables to string objects

**# Task 4**

# Print the result of dividing 783.56 by 123.2 and ensure that the answer results in an integer

# expected outcome: 6

**# Task 5**

# Determine if 2019 is a leap year and print the result.

# expected outcome: 3

**# Task 6**

# Print the calculated length of myFirstString.

# expected outcome: 35

myFirstString = ‘I love working with Python so much!’

**# Task 7**

# Create a string value and print it with the first letter of each word capitalized using a Python method.

**# Task 8**

# Create a string value and determine if the string consists of only lowercase characters. Print the results.

# expected outcome: True or False

**# Task 9**

# Use the given variable to construct a python statement that counts how many times the word pizza is used. Print the final count.

# expected outcome: 3

commercial = ‘In the Little Ceasars pizza commercial the character says, “pizza, pizza”!’

**# Task 10**

# Use the given username and phone to create a message that lets the user know that you will be calling at a specified number for your appointment. Use the format method to insert data into the printed message.

# expected outcome: *Hi, Allen. I will call you at 888-555-0011 for our appointment.*

## Objective 2

The learner constructs functions and control structures to interact with data structures and direct program flow.

# run your function and print the result with integers 7 and 9

# expected outcome: 16

# run your function and print the result with integers 20 and 49

# expected outcome: 69

# expected outcome: 10

**# Task 3**

# You are provided a student’s score on the recent exam. Create a function that will print a reply based on the score. Students who score 90 points or more receive an A and pass the course. Students receiving 80 points or more receive a B and pass the course. Students receiving 79 points or less do not pass and need to retake the exam. Students receiving a score of 0 have not attempted the exam and need instructions to schedule.

print(grade_report(90)) # expected outcome: You received an A and have passed the course.
