这两个列表中的所有值都被 Package 在元组中，因此您应该相应地将它们解包：

calc = [x + y for [x], [y] in zip(first, second)]

问题是你试图添加元组（如果你键入（x）或（y），你会看到那些是元组值，而不是你所拥有的特定浮点数）。如果你想添加元组内部的值，那么你必须访问元素，你可以这样做：

first = [(87.5,), (125.0,), (50.0,)]
    second = [(37.5,), (75.0,), (50.0,)]
    
    calc = [x[0] + y[0] for x, y in zip(first, second)] # accessing the first element of x and y -- as there is only 1 element in each of the tuples. 
    # if you had more elements in each tuple you could do the following: calc = [sum(x) + sum(y) for x, y in zip(first, second)]
    print(calc)
    print(first, second)

如果安装了numpy并且它是您代码的一部分，则有一种方法可以使用numpy：

import numpy as np

first = [(87.5,), (125.0,), (50.0,)]
second = [(37.5,), (75.0,), (50.0,)]

(np.array(first) + np.array(second)).T.tolist()[0]

输出

[125.0, 200.0, 100.0]
