Python program uses anonymous functions to calculate2power

Python instance大全

In this program, you will learn to use Python anonymous functions to display integers2power.

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 find2power.

Source code

# Use anonymous function to display2power
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", power equals, result[i])

Output result

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

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