In Python, a sequence is a collection of objects ordered by their position. 在Python中,有三个基本序列,即列表、元组和所谓的“范围对象”。 In Python, there are three basic sequences,which are lists, tuples, and so-called "range objects". 但是Python也有额外的序列类型来表示字符串之类的东西。

While not a purely functional language, Python supports many functional programming concepts, including treating functions as first-class objects. This means that functions can be passed around and used as arguments, just like any other object like str, int, float, list, and so on. Consider the...
