📘 Python Crash Course – Chapter 6: Dictionaries – Exercise 6-3 Solution

Welcome to another solution from Python Crash Course by Eric Matthes.

📝 Exercise 6-3

Task:
A Python dictionary can be used to model an actual dictionary . However, to avoid confusion, let’s call it a glossary .
• Think of five programming words you’ve learned about in the previous chapters . Use these words as the keys in your glossary, and store their meanings as values .
• Print each word and its meaning as neatly formatted output .
You might print the word followed by a colon and then its meaning, or print the word on one line and then print its meaning indented on a second line .
Use the newline character (\n) to insert a blank line between each word-meaning pair in your output

✅ Solution Code:


glossary = {
    "Indexing" : "The Location of an element",
    "Variables" : "A name given to a value.",
    "loop" : "A block of code that repeats.",
    "list" : "A collection of items in a specific order.",
    "dictionary" : "An unordered collection of key-value pairs."
}

for word,meaning in glossary.items():
    print(f"Word : {word} \nMeaning : {meaning} \n")

🧠 Code Explanation:

This Python code demonstrates how to use a dictionary to create a glossary of programming terms and their meanings. Here's how it works:

  1. Create a glossary dictionary:

    The variable glossary is assigned a dictionary where the keys are programming terms, and the values are their corresponding meanings. For example:

    • "Indexing": "The Location of an element"
    • "Variables": "A name given to a value."
    • "loop": "A block of code that repeats."
    • "list": "A collection of items in a specific order."
    • "dictionary": "An unordered collection of key-value pairs."
  2. Iterate through the glossary:

    The items() method is used to retrieve all key-value pairs from the dictionary. A for loop iterates through these pairs, where word represents the key (programming term) and meaning represents the value (definition).

  3. Display the glossary:

    For each key-value pair, the program displays the word and its meaning in a neatly formatted output. A newline character (\n) is used to insert a blank line between each word-meaning pair for better readability.

This code demonstrates how to use dictionaries to store and retrieve related data, such as programming terms and their definitions, and how to format the output for clarity.

🔍 Output:


Word : Indexing 
Meaning : The Location of an element 

Word : Variables 
Meaning : A name given to a value. 

Word : loop 
Meaning : A block of code that repeats. 

Word : list 
Meaning : A collection of items in a specific order.  

Word : dictionary 
Meaning : An unordered collection of key-value pairs.
