We'll use a lambda expression that takes two parameters for the calculation and then pass in both weights and heights to map(): bmi_iterator = map( lambda x, y: x / (y**2), weights, heights ) for bmi in bmi_iterator:
Since Python handles multiple return values as tuples, each call to powers() returns a tuple with two values. When you call map() with powers() as an argument, you get a list of tuples containing the square and the cube of every number in the input iterable. There are a lot of ...

In this article, we will explore how to use themapfunction with lists in Python and how to decode the results for better understanding. Using themapFunction with Lists Themapfunction takes two arguments: a function and an iterable. The function argument is a callable object that will be appli...

上例中我们给map的处理函数设置为一个匿名函数,它会返回每个遍历数字的自增1的值。 对应到我们单词统计的例子,我们可以使用下面代码,遍历word_count_data每行,然后将其用空格切分出list并返回。这样wordsLists就是“一个元素是一行单词list”的list的迭代器。
Lists 也可以用 + 运算符连接起来。list=list+otherlist相当于list.extend(otherlist)。但 +运算符把一个新 (连接后) 的 list 作为值返回, 而 extend 只修改存在的 list。 也就是说, 对于大型 list 来说, extend Python 支持 += 运算符。 li += ['two'] 等同于 li.extend(['two'])。 += ...
