python 中嵌套数组列表的总最大值

Question

我想要一个获取多个嵌套数组列表和 returns 只有一个数字的函数：输入中出现的所有数字的全局最大值（或最小值）。

例如：

>>> total_max(3.5,[4.5,1,[2,3], np.random.uniform(size=(5,6)),4],[2,-3])
4.5

_{我不想在 Finding The Largest Number in a Nested List in Python or python max of list of arrays. And I want it to also work with numpy arrays, which is not the case for Total max of a nested list.}

中输出多个数字

Answer 1

import numpy as np

def nested_max(nestedList):
  if not (isinstance(nestedList, list)):
    return np.max(nestedList)
  else:
    return max([nested_max(a) for a in nestedList])

def nested_min(nestedList):
  if not (isinstance(nestedList, list)):
    return np.min(nestedList)
  else:
    return min([nested_min(a) for a in nestedList])

def total_max(*args):
  return max([nested_max(a) for a in args])

def total_min(*args):
  return min([nested_min(a) for a in args])

def total_range(*args):
  return total_min(*args), total_max(*args)

这样得到例如：

>>> total_range(3.5,[4.5,1,[2,3], np.random.uniform(size=(5,6)),4],[2,-3])
(-3, 4.5)

_{这可以用于等应用程序，其中可以简单地写：}

mi, ma = total_range(dfz, xx)

^而不是

mi = np.min((dfz.min(), xx.min()))
ma = np.max((dfz.max(), xx.max()))

^{求组合图的总体范围。}

有更好的变体吗？例如：支持更多类型的元组、集合、数组和列表？更短的代码？计算效率更高？
