Selenium Python - Test if an element exists in the page -

-

I'm new to Selenium and I would like to write a Python script that searches for some keywords on Google and automatically The page opens and the keywords are found.

I'm trying to work with the script: 

  Selenium from Selenium Import WebDriver Com.exceptions Import timeout selenium from Akspshn selenium.webdriver.support.ui import webdriver.support.ui import WebDriverWait selenium.webdriver.common.by select Import selenium.webdriver as EC selenium.common.exceptions. imports NoSuchElementException by the support import expected_conditions, then __name__ == "__main__": driver = webdriver.Firefox () wait = WebDriverWait (driver, 100) driver.get ( "http://google.com") inputElement = driver .find_element_by_name ( "q") inputElement.send_keys ( "Irwin Quan") wait.until (EC.element_to_be_clickable ((By.XPATH, "//a[@href='http://irwinhkwan.wordpress.com/ '] "))) Blog = driver.find_element_by_xpat H (" //a[@href='http://irwinhkwan.wordpress.com/ '] ") blog .click () driver.quit ()   
 This works perfectly in the Xpath page, though, if it is not, we always wait for it.  
 How can I check that an element exists, and if it is there, then I click on it?  
 I tried "" as it has been given in the documentation, or  NoSuchElementException , but I "dual deny" - [try: EC driver = webdriver.firefox () Import from imported_conditions to selenium.webdriver.support.ui as driver.get ("// somedomain / url_that_delays_loading http") Import WebDriverWait by webdriver.common.by: element = WebDriverWait (driver, 10) .until (EC.presence_of_element_located ((By.ID, "myDynamicElement"))) finally: driver.quit ()   
 finally, I would like a while loop, which results in Google The page number goes to x and every Salvation is to find a specific address.  
 If someone can give me a hand which will be great! I'm pretty sure that this is trivial, but despite all the documents available availab online I have not been able to do this work for the past few days ...  
 = "post- Text "itemprop =" text "> 
 Here is a little cover for WebAlement I, I've written, hope that it helps  
  class element (object): def __init __ (self, xpath = none): self.xpath = xpath def __get_element (self):. Return driver () find_element_by_xpath (self.xpath) def is_exist (self): try: return self .__ NoSuchElementException, e except get_element () is_displayed () :. Logger.exception (e.message) false return   
 You can not click on the element that is not visible, first you need to expose it, and then only after Click  
 Hope it helps

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
