Week Two: Data Types

In this second week, we dive into how Python categorizes different kinds of information without using variables yet. We will be asking and thinking about the following questions:

What is a data type?
What is the difference between text (strings), whole numbers (integers), decimals (floats), and true/false values (booleans)?
How does Python recognize different values directly?
How do we check a data type using type()?

Presentation

Activity

In this activity, you’ll explore Python’s core data types by printing values and exploring how Python treats different kinds of information.

Concepts you will explore

Strings (str): Text enclosed in quotes (e.g., "Genesis").
Integers (int): Whole numbers without decimals (e.g., 40).
Floats (float): Decimal numbers (e.g., 3.5).
Booleans (bool): True or False values representing logic (e.g., True).
The type() function: How to ask Python what data type a specific value is.


# Printing different data types directly
print("Book of John")         # String (str)
print(12)                     # Integer (int)
print(7.77)                   # Float (float)
print(True)                   # Boolean (bool)

Explore Further

Try printing favorite Bible verses or chapter numbers using different data types.
Experiment with what happens when you put numbers inside quotes versus leaving them unquoted.

Challenges

Choose your difficulty level and put your data type skills to the test!

The Scripture Info Printer

Write a Python program that uses print statements to display information about a Bible book using strings, integers, and booleans.

Requirements:

Print the name of a Bible book as a string.
Print the total number of chapters as an integer.
Print a boolean value representing whether it is in the New Testament (True or False).

Expected Output:


Genesis
50
New Testament: False

View Solution


# Scripture info printer
print("Genesis")
print(50)
print("New Testament:", False)

The Ark Animals Manifest

Check the passage below to see how many pairs of clean and unclean animals and birds Noah brought onto the ark based on Genesis 7:2-3.

View Genesis 7:2-3 (NASB) Passage

“You shall take with you of every clean animal by sevens, a male and his female; and of the animals that are not clean two, a male and his female; also of the birds of the sky, by sevens, male and female, to keep offspring alive on the face of all the earth.”

Create a script using print() statements that follows the table below to display each creature, its pair count, and whether it is clean. Use the reference links to check the specific details for each animal.

Animal / Bird	Pair Count	Clean Status	Bible Reference
Sheep	`7`	`True`	Leviticus 11:3
Pig	`2`	`False`	Leviticus 11:7
Dove	`7`	`True`	Genesis 8:8-9
Raven	`2`	`False`	Genesis 8:7

Expected Output:


Animal: Sheep - Pairs: 7 - Clean: True
Animal: Pig - Pairs: 2 - Clean: False
Animal: Dove - Pairs: 7 - Clean: True
Animal: Raven - Pairs: 2 - Clean: False

View Solution


# Ark manifest based on Genesis 7:2-3 and research references
print("Animal: Sheep - Pairs: 7 - Clean:", True)
print("Animal: Pig - Pairs: 2 - Clean:", False)
print("Animal: Dove - Pairs: 7 - Clean:", True)
print("Animal: Raven - Pairs: 2 - Clean:", False)

The Scripture Data Type Inspector

Build an advanced script that prints a header, shows scripture values, uses a divider line (=====), displays their corresponding data types using type(), and ends with a footer.

Note for context: The entire Bible contains 1,189 total chapters. The Book of Psalms has 150 chapters, making up roughly 12.61% of all chapters in the Bible, and Psalms is part of the Old Testament (True for Old Testament).

Requirements:

Print a header: === BIBLE DATA INSPECTOR ===.
Print four separate labeled values: Verse, Chapters, Percentage, and Old Testament status.
Print a divider line: =====.
Print four separate labeled lines using type() to reveal the data type for each value in order.
Print a footer: === INSPECTION COMPLETE ===.

Expected Output:


=== BIBLE DATA INSPECTOR ===
Verse: Psalm 23:1
Chapters: 150
Percentage: 12.61
Old Testament: True
=====
Verse Type: <class 'str'>
Chapters Type: <class 'int'>
Percentage Type: <class 'float'>
Old Testament Type: <class 'bool'>
=== INSPECTION COMPLETE ===

# Data type inspector script with header and footer 
print("=== BIBLE DATA INSPECTOR ===") 
print("Verse: Psalm 23:1") 
print("Chapters:", 150) 
print("Percentage:", 12.61) 
print("Old Testament:", True)          
print("=====")          
print("Verse Type:", type("Psalm 23:1")) 
print("Chapters Type:", type(150)) 
print("Percentage Type:", type(12.61)) 
print("Old Testament Type:", type(True)) 
print("=== INSPECTION COMPLETE ===")
