每个元组的最大值

Question

如何找到每个元组的最大值。

lst1 = [(4, 1, 9, 22, 6, 14),( 7, 22, 9, 2, 1, 2 )]
lst2 = map(max, zip(*lst1))
print(lst2)  

Answer 1

在Python 3中：

In [1]: lst1 = [(4, 1, 9, 22, 6, 14),( 7, 22, 9, 2, 1, 2 )]

In [8]: tuple(map(max, lst1))
Out[8]: (22, 22)

Answer 2

列表理解方式是

lst2 = [max(x) for x in lst1]
