Inside rotate_chr(), you first check if the character is in the alphabet. If not, then you return the same character. This has the purpose of keeping punctuation marks and other unusual characters. In line 8, you calculate the new rotated position of the character in the alphabet. To do...
一个case子句可以选择有一个守卫,这是一个if语句,允许您应用布尔条件,这些条件必须为 true 以匹配case子句。有点像列表理解中的if语句。 每个case子句获取一个语句代码块,如果子句是match块中第一个匹配主题的子句,则执行该语句代码块。如果您想使用return、yield或者,比方说,与case子句语句块中的数据库对话,您可...
Next, you join a list of six single-character strings to form the string "Python". Finally, you read the string from user input using input(). The final test shows that the value of each string is the same. In most applications, you don’t need to care about how a particular string...
