📘 Python Crash Course – Chapter 4: Working With Lists – Exercise 4-2 Solution
Welcome to another solution from Python Crash Course by Eric Matthes.
📝 Exercise 4-2
Task:
Think of at least three different animals that have a common char
acteristic . Store the names of these animals in a list, and then use a for loop to
print out the name of each animal .
• Modify your program to print a statement about each animal, such as
A dog would make a great pet.
• Add a line at the end of your program stating what these animals have in
common . You could print a sentence such as Any of these animals would
make a great pet!
✅ Solution Code:
animals = ["dog",'cat','parrot']
for animal_name in animals:
print(animal_name)
print("-----------------------------------------------------------")
for animal_name in animals:
print(f'A {animal_name} would make a great pet')
print("-----------------------------------------------------------")
for animal_name in animals:
print(f'A {animal_name} would make a great pet')
print("All of them are friendly in nature")
print("-----------------------------------------------------------")
🧠 Code Explanation:
This Python code demonstrates how to use a list and a for loop to iterate through items and print personalized messages about animals. Here's how it works:
-
Create a list of animals:
The variable
animalsis assigned a list containing three animals:["dog", "cat", "parrot"]. -
Print each animal name:
A
forloop is used to iterate through theanimalslist, and theprint()function is used to display each animal name. -
Print personalized statements:
The
forloop is modified to include an f-string that prints a personalized statement for each animal, such as"A dog would make a great pet". -
Add a concluding statement:
After the loop, a final statement is printed outside the loop, expressing a general characteristic of all the animals in the list. For example,
"All of them are friendly in nature".
🔍 Output:
dog
cat
parrot
-----------------------------------------------------------
A dog would make a great pet
A cat would make a great pet
A parrot would make a great pet
-----------------------------------------------------------
A dog would make a great pet
A cat would make a great pet
A parrot would make a great pet
All of them are friendly in nature
