Python 实现两个列表里元素对应相乘的方法今天小编就为大家分享一篇Python 实现两个列表里元素对应相乘的方法，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧立即下载

列表之和计算

使用sum函数

numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
print(sum(numbers))

使用reduce函数

# 方式1
from functools import reduce

numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
results = reduce(lambda x, y: x + y, numbers)
print(results)


# 方式2
from operator import add
from functools import reduce

numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
results = reduce(add, numbers)
print(results)

使用for循环

numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

result = 0
for number in numbers:
    result += number
print(result)

使用递归

numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

def cal(list1, size):
    if size:
        return list1[size - 1] + cal(list1, size - 1)
    return size

print(cal(numbers, len(numbers)))

列表乘积计算

使用for循环

numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]


result = 1

for number in numbers:

    result *= number

print(result)

使用reduce函数

# 方式1
from functools import reduce

numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

results = reduce(lambda x, y: x * y, numbers)
print(results)

# 方式2
from operator import mul
from functools import reduce

numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
results = reduce(mul, numbers)
print(results)

使用递归函数

numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

def cal(list1, size):
    if size == 0:
        return 1
    return list1[size - 1] * cal(list1, size - 1)

print(cal(numbers, len(numbers)))
