print("FAILED: {}.".format(student)) # Increase the counter by 1 and prepare for the next student ind += 1 这是我们之前讲的一个例子,换成for之后就长这样: # Given a list of students' name student_list = ['Alice', 'Bob', 'Cat', 'David', 'Evan', 'Frank', 'Gary', ] # Loop...

.format(student)) # Increase the counter by 1 and prepare for the next student ind = ind + 1 该程序会从下标为0的学生Alice开始问分数、决定成绩,直到问到这个列表结束,也就是最后一个询问的对象是Gary。 这里我们是怎么确保循环会照顾到每一个学生而且不多不少正好从第一个问到最后一个呢?我们来...

CC BY-NC-SA 4.0 前言 在本书开始时,我们努力展示了 Python 在当今数字调查中几乎无穷无尽的用例。技术在我们的日常生活中扮演着越来越重要的角色,并且没有停止的迹象。现在,比以往任何时候都更重要的是,调查人员必须开发编程技能,以处理日益庞大的数据集。通过利用本书中探讨的 Python 配方,我们使复杂的事情变得...
And after it's done, the ALU is going to go back, and the program counter is going to increase by 1, which means that we're going to go to the next sequence in the instruction set. And it just goes linearly instruction by instruction. 但是,存在一种instruction that does some sort of...
Would you like a set of problems that increase in difficulty to practice and hone your Python skills? This week on the show, we have Jim Anderson to talk about his new Real Python article, "Python Practice Problems: Get Ready for Your Next Interview." This article provides several problems...

简单的 Go 版本可以使用 buffio.Scanner，并使用 ScanWords 来分割单词。Go 没有 Python 的 collections.Counter，但使用 map[string] 进行计数也非常简单，然后通过单词和计数组成的切片进行排序操作：simple.gofuncmain() { scanner := bufio.NewScanner(os.Stdin) scanner.Split(bufio.ScanWords) counts...
