在下面的程序中，我们使用了 map() 内置函数中的匿名（lambda）函数来查找2的幂。
源代码
# 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
注意：要测试不同项数，请更改 terms 变量的值。
