使用匿名函数显示2的x次方的 Python 程序

2022-05-03 00:00:00 函数 次方 匿名

在这个程序中,您将学习如何使用 Python 匿名函数显示整数2的幂。
在下面的程序中,我们在 map ()函数中使用了一个匿名(lambda)函数来查找2的幂。
源代码如下:

# 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])

输出:

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

要现实不同的幂值,只需要修改terms的值即可。
