如何使用python中的for循环添加2D数组中的值

if __name__ == '__main__':

scores = [[8, 1], [5, 3], [3, 5], [8, 1], [7, 1], [1, 0], [9, 0], [5, 0], [6, 0], [8, 1, 0]]
#scores_int = 0;
#scores_int = len(scores);
sum = 0;


for row in range(len(scores)):
    sum = scores[0]
print(sum)
print(scores[0:1])
print(scores[1][0])
   #print("Sum of all all the socres:", sum);

因此，我试图找出一种循环浏览数组的每个实例，并将值添加到总和变量中的方法，但是我不明白如何循环循环2D数组。得分总和应等于72 我只需要语法帮助for循环

if __name__ == '__main__':

scores = [[8, 1], [5, 3], [3, 5], [8, 1], [7, 1], [1, 0], [9, 0], [5, 0], [6, 0], [8, 1, 0]]
#scores_int = 0;
#scores_int = len(scores);
sum = 0;


for row in range(len(scores)):
    sum = scores[0]
print(sum)
print(scores[0:1])
print(scores[1][0])
   #print("Sum of all all the socres:", sum);

So im trying to figure out a way to loop through every instance of the array and add the values in them to a sum variable, but i dont understand how to loop through a 2d array. The score sum should equal 72
i just need syntax help with the for loop

我的建议，如果您只是为了尝试您不知道的事情。
下次您可以打印所有数字列表，然后尝试将其概括，avg或计算其中的数字

if __name__ == '__main__':
    scores = [[8, 1], [5, 3], [3, 5], [8, 1], [7, 1], [1, 0], [9, 0], [5, 0], [6, 0], [8, 1, 0]]
    total = 0
    
    for list_of_number in scores:
        # print(list_of_number)
        total += sum(list_of_number)
    
    print(total)

My advice if you're begginer is just to experiment with things you don't know.
Next time you could print all the list of numbers and then try to sum it , avg it, or count the numbers inside it

if __name__ == '__main__':
    scores = [[8, 1], [5, 3], [3, 5], [8, 1], [7, 1], [1, 0], [9, 0], [5, 0], [6, 0], [8, 1, 0]]
    total = 0
    
    for list_of_number in scores:
        # print(list_of_number)
        total += sum(list_of_number)
    
    print(total)
