Python program uses anonymous functions to calculate2to the power

Python example in full

In this program, you will learn to use Python anonymous functions to display integers2to the power

To understand this example, you should understand the followingPython programmingTopic:

• Python for loop

• Python anonymous/ Lambda function

In the following program, we use an anonymous (lambda) function inside the map() built-in function to find2to the power

Source code

# Use anonymous function to display2to the power
terms =　10
# The following code is commented out to accept user input
# terms = int(input("How many items? "))
# Use anonymous function
result = list(map(lambda x:　2　**　x, range(terms)))
print("Total number of items:", terms)
for i in range(terms):
　　　print("2of "i", "to the power of", result[i])

Output result

Total number of items:　10
2of 0 to the power of　1
2of　1　to the power of　2
2of　2　to the power of　4
2of　3　to the power of　8
2of　4　to the power of　16
2of　5　to the power of　32
2of　6　to the power of　64
2of　7　to the power of　128
2of　8　to the power of　256
2of　9　to the power of　512

Note:To test different numbers of items, please change the value of the terms variable.
