Python Program To Display Powers of 2 Using Anonymous Function (lambda Function)

Here in this tutorial, we will talk about a Python program that can print the powers of 2 using the Python lambda or Anonymous function.

Python Concepts Utilized in the Program

  • Python Input, Output
  • Lambda function
  • Python Operators
  • Python Loop
  • Map function

Steps to Create the Program

  • First, we ask the user to enter a number n, which represents the number up to which the user wants to print the power of 2.
  • By using the int() function, we will convert the entered string into an integer value.
  • Next, we need to use the map and lambda functions to create a map object which contains all the values of 2 raised to the power n.
  • Now, we use a list that converts the map object into a list.
  • At last, by using the for loop, we will print all the 2 raised to the power n values.

Note:

map(function, container): map() is an in-built and powerful function in Python that accepts 2 arguments, namely function and container (list, tuple, etc..). The map function picks a value from the container one by one and passes it into the function for each value.

lambda function: It is also known as the anonymous function, and it is an easy and quick hand technique to write small user-defined functions.

Python Program to Display Powers of 2 Using Anonymous Function (lambda Function)

Code:

n = int(input("Enter the number up to which you want to print the power of 2:" ))

pow_2_lambda = lambda x:2**x
list_of_2_pow = list(map(pow_2_lambda,list(range(n+1))))
for i in range(n+1):
    print("2 raised to the power", i, "is", list_of_2_pow[I])

Output 1:

Enter the number up to which you want to print the power of 2:10
2 raised to the power 0 is 1
2 raised to the power 1 is 2
2 raised to the power 2 is 4
2 raised to the power 3 is 8
2 raised to the power 4 is 16
2 raised to the power 5 is 32
2 raised to the power 6 is 64
2 raised to the power 7 is 128
2 raised to the power 8 is 256
2 raised to the power 9 is 512
2 raised to the power 10 is 1024

Output 2:

Vamware
Enter the number up to which you want to print the power of 2:17
2 raised to the power 0 is 1
2 raised to the power 1 is 2
2 raised to the power 2 is 4
2 raised to the power 3 is 8
2 raised to the power 4 is 16
2 raised to the power 5 is 32
2 raised to the power 6 is 64
2 raised to the power 7 is 128
2 raised to the power 8 is 256
2 raised to the power 9 is 512
2 raised to the power 10 is 1024
2 raised to the power 11 is 2048
2 raised to the power 12 is 4096
2 raised to the power 13 is 8192
2 raised to the power 14 is 16384
2 raised to the power 15 is 32768
2 raised to the power 16 is 65536
2 raised to the power 17 is 131072
