📘 Python Crash Course – Chapter 4: Working With Lists – Exercise 4-8 Solution
Welcome to another solution from Python Crash Course by Eric Matthes.
📝 Exercise 4-8
Task:
A number raised to the third power is called a cube .
For example,
the cube of 2 is written as 2**3 in Python .
Make a list of the first 10 cubes (that
is, the cube of each integer from 1 through 10), and use a for loop to print out
the value of each cube
✅ Solution Code:
num = list(no**3 for no in range(1,11))
for data in num:
print(data)
🧠 Code Explanation:
This Python code demonstrates how to generate a list of cubes of numbers and iterate through it using a for loop. Here's how it works:
-
Generate a list of cubes:
A list comprehension is used to calculate the cube of each number in the range from 1 to 10. The expression
no**3raises each numbernoto the power of 3, and therange(1, 11)function generates numbers from 1 to 10 (inclusive). The resulting list of cubes is stored in the variablenum. -
Iterate through the list:
A
forloop is used to iterate through each cube in thenumlist. The variabledatatakes on each value in the list, one at a time.
This code demonstrates how to use list comprehensions to perform mathematical operations on a sequence of numbers and how to iterate through the resulting list.
