基本编程概念:理解核心编程概念,如函数、循环和条件。 Python函数经验:熟悉在Python中定义和使用函数,包括使用参数和返回值。 Python类和对象的基本理解:尽管本课程侧重于函数式编程,但了解Python面向对象功能的基础知识是有益的。熟悉基本数据结构:熟悉Python的标准数据结构,如列表、集合和字典及其常见操作。问题解决技能...
You’ll wrap it up, putting your newfound knowledge to use by creating a few more examples that might be useful in the real world. Slowing Down Code, Revisited As noted earlier, your previous implementation of @slow_down always sleeps for one second. Now you know how to add parameters to...
在Python中,slice对象是一种用于指定序列访问范围的便捷方式,它广泛应用于列表、字符串、元组等多种序列类型中。slice对象可以通过直接构造或使用切片语法糖创建 ,为数据访问和操作提供了灵活性。例如,slice(1, 5)等同于切片语法[1:5] ,其中起始索引为1(包含),结束索引为5(不包含)。 1.2 简单切片语法 [start:s...
In real-world examples, the class hierarchy can get quite complicated. The super() function does much more than just search the parent class for a method or an attribute. It traverses the entire class hierarchy for a matching method or attribute. If you aren’t careful, super() can have...
The Q Pai Programming Thinking Bootcamp, based on the Project-Based Learning model, immerses students in real-world scenarios to foster a self-directed, problem-focused learning process. By using a hardware platform, students engage in practical, exploration-driven learning through workshops and optim...

{x: x**2 for x in (2, 4, 6)} 该代码使用的是字典推导式,更多推导式内容可以参考:Python 推导式。另外,字典类型也有一些内置的函数,例如 clear()、keys()、values() 等。注意:1、字典是一种映射类型,它的元素是键值对。 2、字典的关键字必须为不可变类型,且不能重复。 3、创建空字典使用 { }。
