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 :
nums = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
print("Original list of integers:")
print(nums)
print("\nSquare every number of the said list:")
square_nums = list(map(lambda x: x ** 2, nums))
print(square_nums)
print("\nCube every number of the said 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]

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
