Python: Square and cube every number in a given list of integers using Lambda

Python Lambda: Exercise-6 with Solution

Write a Python program to square and cube every number in a given list of integers using Lambda.

Sample Solution:

Python Code :

# Create a list of integers named 'nums'
nums = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

# Display a message indicating that the following output will show the original list of integers
print("Original list of integers:")
print(nums)

# Display a message indicating that the following output will show each number in the list squared
print("\nSquare every number of the said list:")

# Use the 'map()' function with a lambda function to square each number in the 'nums' list
# Create a new list 'square_nums' containing the squared values of the original list
square_nums = list(map(lambda x: x ** 2, nums))
print(square_nums)

# Display a message indicating that the following output will show each number in the list cubed
print("\nCube every number of the said list:")

# Use the 'map()' function with a lambda function to cube each number in the 'nums' list
# Create a new list 'cube_nums' containing the cubed values of the original list
cube_nums = list(map(lambda x: x ** 3, nums))
print(cube_nums) 

Sample Output:

Original list of integers:
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Square every number of the said list:
[1, 4, 9, 16, 25, 36, 49, 64, 81, 100]

Cube every number of the said list:
[1, 8, 27, 64, 125, 216, 343, 512, 729, 1000]

Explanation:

In the exercise above -

• Initializes a list named 'nums' containing integers from 1 to 10.
• Prints the original list of integers (nums) to the console.
• Uses the "map()" function along with lambda functions to perform mathematical operations on each number in the 'nums' list:
• The code uses "map()" with a lambda function to square each number in the 'nums' list.
• It creates a new list named 'square_nums' containing the squared values of the original list.
• Then, it uses "map()" with another lambda function to cube each number in the 'nums' list.
• It creates a new list named 'cube_nums' containing the cubed values of the original list.
Prints both the list of squared numbers ('square_nums') and the list of cubed numbers ('cube_nums') to the console.
