python any all函数

a = [0, 0, 0, 0]
b = [0, 0, 0, 1]
c = [1, 1, 1, 1]

>>> any(a)
False

>>> any(b)
True

>>> any(c)
True

Return True if bool(x) is True for any x in the iterable.If the iterable is empty, return False.
当传入空可迭代对象时返回False，当可迭代对象中有任意一个为true，则返回True

>>> all(a)
False

>>> all(b)
False

>>> all(c)
True

Return True if bool(x) is True for all values x in the iterable.If the iterable is empty, return True.
当传入空可迭代对象时返回True，当可迭代对象中有任意一个不为True，则返回False
