If the expression list in thereturnstatement contains at least one comma, except when part of a list or set display, it returns a tuple. The length of the tuple is the number of expressions in the list. The expressions are evaluated from left to right. 如果return语句中的表达式列表包含至少...

本文实例讲述了Python3.2中Print函数用法.分享给大家供大家参考.具体分析如下: 1. 输出字符串 >>> strHello = 'Hello World' >>> print (strHello) Hello World 2. 格式化输出整数 支持参数格式化,与C语言的printf类似 >>> strHello = "the length of (%s) is %d" %('Hello World',len('Hello Python...

分别定义函数如下: def _removeSalutation(name: String) : String = { val salutationList = List("MRS", "MR", "MSTR", "MISS", "MS", "DR") for(salutation <- salutationList){ if(name.endsWith(salutation)){ return name.dropRight(salutation.length()) } } return name}val removeSalutation ...
If the input sequences are not of equal length,map()will stop at the termination of the shortest of the sequences. For full compatibility withmap()from Python 2.x, also wrap the sequences initertools.zip_longest(), e.g.map(func,*sequences)becomeslist(map(func,itertools.zip_longest(*se...
一般情况下,在Python无法正常处理程序时就会发生一个异常。 异常是Python对象,表示一个错误。 当Python脚本发生异常时我们需要捕获处理它,否则程序会终止执行。 二、异常处理 捕捉异常可以使用try/except语句。 try/except语句用来检测try语句块中的错误,从而让except语句捕... ...
您试图在Rectangle构造函数中默认构造两个Line(width和length)。因为Line没有默认构造函数,所以需要使用成员初始值设定项列表: Rectangle::Rectangle() : // colon starts the member initializer list width(Point(0,4), Point(0,0)), length(Point(0,0), Point(8,0)){} ...
