Python Program to Display Powers of 2 Using Anonymous Function

In this program, you’ll learn to display powers of the integer 2 using Python anonymous function.

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

• Python for Loop
• Python Anonymous/Lambda Function

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

Source Code

# Display the powers of 2 using anonymous function

terms = 10

# Uncomment code below to take input from the user
# terms = int(input("How many terms? "))

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

print("The total terms are:",terms)
for i in range(terms):
   print("2 raised to power",i,"is",result[i])

Output

The total terms are: 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

Note: To test for different number of terms, change the value of terms variable.
