Python built-in function - all(iterable)

Python内建函数之all(iterable)

Manual

Return True if all elements of the iterable are true (or if the iterable is empty). Equivalent to:

def all(iterable):
    for element in iterable:
        if not element:
            return False
    return True

直译

如果序列所有元素为真或空序列则返回True。
