Python Program To Display Powers of 2 Using Anonymous Function

To understand this example, you should have knowledge of following Python programming topics:

Python for Loop

Python Anonymous/Lambda Function

Source Code

# Python Program to display the powers of 2 using anonymous function

# Take number of terms from user
terms = int(input("How many terms? "))

# use anonymous function
result = list(map(lambda x: 2 ** x, range(terms)))

# display the result
for i in range(terms):
   print("2 raised to power",i,"is",result[i])

Output

How many terms? 10
2 raised to power 0 is 1
2 raised to power 1 is 2
2 raised to power 2 is 4
2 raised to power 3 is 8
2 raised to power 4 is 16
2 raised to power 5 is 32
2 raised to power 6 is 64
2 raised to power 7 is 128
2 raised to power 8 is 256
2 raised to power 9 is 512

In this program, we have used anonymous (lambda) function inside the map() built-in function to find the powers of 2.
