syntaxError: 'continue' not properly in loop

夙愿已清 提交于 2019-12-04 03:19:18
I have been struggling with this error for a while now and there seems to be different opinions regarding why the interpreter complains about the 'continue'. So I would like to provide the erroneous code below. import tweepy import time def writeHandlesToFile(): file = open("dataFile.txt","w") try: list = tweepy.Cursor(tweepy.api.followers,screen_name='someHandle',).items(100000) print "cursor executed" for item in list: file.write(item.screen_name+"\n") except tweepy.error.TweepError as e: print "In the except method" print e time.sleep(3600) continue The reason I am particular on including

Which statement will be executed after "continue" or "break" ? for(int i = 0; i < count; ++i) { // statement1 for(int j = 0; j < count; ++j) { //statement2 if(someTest) continue; } //statement3 } for(int i = 0; i < count; ++i) { // statement1 for(int j = 0; j < count; ++j) { //statement2 if(someTest) break; } //statement3 } Petar Ivanov continue: ++j and then if j < count then statement2 otherwise statement3 break: statement3 Continue jumps straight to the top of the innermost loop, where the per-iteration code and continuance check will be carried out (sections 3 and 2 of the for loop).

流程控制即控制程序的执行流程 程序的执行流程分为三种结构:1、顺序结构                2、分支结构(if语句)               3、循环结构(while、for语句) 分支结构,if:主要用于判断事物对错,是否可行。 语法结构: if 条件1: 代码块1 ... elif 条件2: 代码块2 elif 条件3: 代码块3 ...... else: 代码块n if...elif...else:同一个代码结构里只会执行一个,例如执行if就不会执行elif和else。 案例1: gender = 'female' age = 18 is_beauty = True if gender =='female' and 16 < age < 26 and is_beauty: print('Wow') elif 16 < age < 36 and is_beauty: print('Hah') else: print('Emm..') 案例2 模拟认证功能:1、接收用户的输入           2、判断用户的输入结果             3、返回数据 username = 'Bill' password = '123' inp_username = input('input your username:') inp_password = input(

When to use the 'continue' keyword in C#

安稳与你 提交于 2019-12-03 06:23:08
问题 Recently, I was going through an open-source project and although I have been developing for several years in .NET, I hadn't stumbled across the continue keyword before. Question: What are some best practices or areas that would benefit from using the continue keyword? Is there a reason I might not have seen it previously? 回答1: You use it to immediately exit the current loop iteration and begin the next, if applicable. foreach (var obj in list) { continue; var temp = ...; // this code will

Is it possible to use 'yield' to generate 'Iterator' instead of a list in Scala?

问题 Is it possible to use yield as an iterator without evaluation of every value? It is a common task when it is easy to implement complex list generation, and then you need to convert it into Iterator , because you don't need some results... 回答1: Sure. Actually, there are three options for non-strictness, which I list below. For the examples, assume: val list = List.range(1, 10) def compute(n: Int) = { println("Computing "+n) n * 2 } Stream . A Stream is a lazily evaluated list. It will compute
