如何制作nums列表？

Question

我目前有：

def product_of_tuples(nums_list):
    '''Receives a list of tuples of two or more numbers. Returns
    a list of the products of the numbers in each tuple. (Note:
    the product of a sequence of numbers is obtained by multiplying
    them together.)'''

    result = []
    for numbers in nums_list:
        *# ''' need something here '''*
        for num in numbers:
            multi_number = num * num 
        result.append(multi_number)
    return result

运行时

print(product_of_tuples([(1, 5), (6, 1), (2, 3, 4)]))预期输出应为[5, 6, 24]

任何建议都将受到赞赏：）

Answer 1

你搞砸了内心。由于这是乘法，你需要每次将累加器重置为1，然后你需要依次将它乘以每个数字。

Answer 2

from operator import mul

def product_of_tuples(nums_list):
    '''Receives a list of tuples of two or more numbers. Returns
    a list of the products of the numbers in each tuple. (Note:
    the product of a sequence of numbers is obtained by multiplying
    them together.)'''

    return [reduce(mul, i) for i in nums_list]

Answer 3

我认为你应该逐个乘以每个元组中的数字，但是num * num给出平方。我可以试试这个：

def product_of_tuples(nums_list):
result = []
for tuple in nums_list:
    s = 1
    for item in tuple:
        s *= item
    result.append(s)
return result
