NameError: name'area'isnotdefined area是函数中的局部变量,因此我们无法从函数外部访问它。 6.2. 有些函数返回 None 如果一个函数没有return语句,它会返回None,这是一个特殊的值,类似于True和False。例如,这里是第三章中的repeat函数。 defrepeat(word, n):print(word * n) ...
def _not_divisible(n): return lambda x: x % n > 0 1. 2. 而在这里,我们要注意的是,n是指代不算刚刚产生的所有n,而x是刚刚产生的n,而这个代码就是将x与之前产生过的所有素数进行取余以确定x是否是素数的倍数。 yield n it = filter(_not_divisible(n), it) # 构造新序列 ...
