Append lists for CSV output in Python

由 时光总嘲笑我的痴心妄想 提交于 2019-12-13 06:02:21
问题 At the moment I am scraping data from the web and want to output it into CSV. Everything is working fine but as soon as I append more than one list in the iteration the list has the wrong format. I start with sth like this: list = [a, b, c] list_two = [d, e, f] list_three = [g, h, i] first iteration: list = [list, list_two] # list = [[a, b, c], [d, e, f]] second iteration: list = [list, list_three] I get: # list = [[[a, b, c], [d, e, f]], [g, h, i]] I want to have: # list = [[a, b, c], [d, e,

Append dynamic div just once and a JSFiddle issue

问题 This code is doing everything I want the first time a table node is clicked (image is added etc). However, when a second node is clicked the choices appear again, but twice and so on. Is there a way for me to append the elements just once. I have created a fiddle of the problem. It is working in Chrome, but not on the JSFiddle itself. Perhaps I am doing something incorrectly. http://jsfiddle.net/Inkers/NyxCu Thanks. <html> <head> <meta name = "viewport" content="width=device-width, height=

Reading a File in C: different behavior for “r” and “a+” flags

由 人盡茶涼 提交于 2019-12-13 06:00:14
问题 I want to open a file, read its contents, and then append a line to the file. I thought I should use the "a+" flag for the task. I have a function which opens a file and returns a pointer to this file. FILE* open_weekly_disk_file(char* filename){ FILE* weekly_log; weekly_log = fopen(filename, "a+"); //weekly_log = fopen(filename, "r"); if(! weekly_log){ printf("The attempt to open the weekly log failed!\n"); return NULL; } else{ return weekly_log; } } Then I have a function which calls the

Jquery appended input button doesn't function with .on(click)

由 孤人 提交于 2019-12-13 05:42:35
问题 jsFiddle of my code: http://jsfiddle.net/8Vcyu/ I have setup a form where the user can input between 1 and 10 lines of information. If the user adds a 10th line jquery removes the 'add row' button. If the 10th line is removed the add button comes back. This all works well, but when the 'add row' button is appended back into the page, it no longer functions - no new row is added. Any help is really appreciated, this problem is stumping me.

Deserializing but not adding to previous xml

由 笑着哭i 提交于 2019-12-13 05:39:38
问题 In relation to my other question, I have serialized data and then deserialized it, but when I write new data to the deserialized arraylist, it does not add the new data to the end of the arraylist. Instead it is overwriting previous list data. Any help would be great. Here's my code so far: { ArrayList siteList = new ArrayList(); ArrayList copy = new ArrayList(siteList); //if previous data exists, deserialize it try { ArrayList deserializedArray = DeserializeArray(); foreach (var item in

Python appending two returns to two different lists

由 老子叫甜甜 提交于 2019-12-13 04:39:38
问题 I am wanting to append two returned lists to two different lists such as def func(): return [1, 2, 3], [4, 5, 6] list1.append(), list2.append() = func() Any ideas? 回答1: You'll have to capture the return values first, then append: res1, res2 = func() list1.append(res1) list2.append(res2) You appear to be returning lists here, are you certain you don't mean to use list.extend() instead? If you were extending list1 and list2 , you could use slice assignments: list1[len(list1):], list2[len(list2)

问题 I'm trying to append to a list in Python 3 but want to do this in the shortest amount of lines possible. In order to do this, I have created a blank 1D array and used basic iteration to append to it.

However, I wanted to know if this is possible to achieve? I'd like the output to be like the following: [First name, Second name],
