问题 I would like to use Selenium to submit a form which contains several elements. For example: <form name="something"> <input type="text" name="a">Username</input> <input type="password" name="b">password</input> <select name="c" id="c"> <option value="1">1</option> <option value="2">2</option> </select> <input type="submit" name="submit">submit</input> </form> If I use find.Element(By.name) to find out the form element, how can I get its children elements a, b, and c? And input the values into

问题 I have a version of this code working but it seems overly complex. This is the simplified version im getting stuck on. in python3. list1 = [['a', 'b'], ['a', 'c'], ['a', 't'], ['x', 'f'], ['x', 'g'], ['d', 'z']] z = len(list1) for i in range(0, z): for j in range(i + 1, z): while list1[i][0] == list1[j][0]: list1[i] = list1[i] + [list1[j][-1]] if list1[j] in list1: list1.remove(list1[j]) z = z - 1 I want output. [['a', 'b', 'c', 't'], ['x', 'f', 'g'], ['d', 'z']] 回答1: Modding Darryl's a bit:

问题 I've got an array of objects. Some of them have a wordpress_parent prop with a value `. This means this node is a child of another node. The actual end result is a nested comment UI, so there can be multiple levels of children. I'd like to loop through my objects and where wordpress_parent !== 0 , find the object in the original array whose wordpress_id equals the value of wordpress_parent and put that object as a child property of the matching parent node. I want to achieve this object form:

问题 I wrote a function to trim white space characters from a string in C. My concern is the last line in the trim() function below, where the source is contained in the destination. The test cases all turned out fine, along with some other testing. Can copying all or a portion of a string where the source and destination are in the same memory cause weird problems? Source code: #include <stdio.h> #include <string.h> void trim(char *line) { int i, len = strlen(line); char *ptr, whitespace[] = " \t

问题 Say I have the following JSON: { "a": 0, "b": "c", "d": { "e": { "f": "g", "comments": { "leading": "Lorem ipsum" }, "h": { "i": { "j": [ 1, 2 ] }, "comments": { "trailing": "dolor sit" } } }, "comments": { "leading": "amet." } } } I want to get an array with the values of all the fields named comments (which can be nested in any level). So, in this case I want to get: [ { "leading": "Lorem ipsum" }, { "trailing": "dolor sit" }, { "leading": "amet." } ] The order of the array doesn't matter.

问题 Suppose I have the following in my models.py: class Book: pass class Part: book = models.ForeignKey(Book) class Chapter: part = models.ForeignKey(Part) number = models.IntegerField() I would like to do book = Book.objects.get(id=someID) chapters = Book.chapters.get(number=4) What is a clean way to do so? I thought of a Manager on the book class but it doest not seem to work for this case. Of course I could implement a method get_chapters on class book but i would like to avoid this. any ideas
