                                                                                  If you click on "view page source" in your browser you can ctrl+f for the phone number:

                                                                                  So you don't need to emulate browser and button clicking - everything is there!

                                                                                  Now lets see how we can scrape this data just by using requests (or any other http client like httpx or aiohttp):

                                                                                  import requests

I suggest googling "regex python tutorial" if you want to learn more but I can explain the pattern we're using here: we want to capture everything in double-quotes that follows "phoneNumber":" string and is either a digit (marked as \d) or a dash (marked as simply -).

                                                                                  This requests script would only take few seconds to complete and use almost no computing resources. However one thing to watch out when using http client compared to Selenium browser emulation is bot blocking which often requires quite a bit of development work to get around though performance gains are really worth it!

                                                                                  Currently while updating in the backend getting error.

I can confirm that I do indeed have an image by given name in the specified directory.

The imread() function will not return anything to your imgTrainingNumbers matrix if you... a. have not specified the path correctly b. the image is not in a proper format/is corrupted c. some linking issue

However I am struggling at the moment. Currenly with this line of code Set nextPageElement = HTML.getElementsByClassName("paginationMini--right__active")(0) I can loop X amount of times however it is NOT changing the page, the page always remains page 1, therefore if I stated 3 pages it will pull the same data off page1 THREE times. When it should change the page 3 times.

                                                                                  I have tried several variations and have left a few commented out in the code below. All off the attempts end after the first page, the above line of code is the only one that loops the code 3 times but is not changing the page. I have always used this code so I do know that it works. Please could someone point out the correct class.

                                                                                  Link

As the image below shows I can get all the other required information. I have tried several variations for the class as well as trying to get it via the a Tag, however I can not work it out.

                                                                                  link

                                                                                  I have a dataframe resulting from a web-scrape. In there I have a data['Milage'] column that has the following result: '80,000 miles'. Obviously that's a string, so I'm looking for a way to erase all content that isnt numeric and convert that string to straigt numbers '80,000 miles' -> '80000'

                                                                                  I tried the following:

                                                                                  data['Milage'] = data['Milage'].str[1:].astype(int)

                                                                                  data['Milage'] = str(data['Milage']).extract('(\d+)').astype(int)

                                                                                  I think you need remove non numeric values and convert to integers:

                                                                                  df['Milage'] = df['Milage'].str.replace('\D','').astype(int)

It is different from what you saw in dev tool, to see source of site, you can press Ctr+U. Then you can see that the description is in meta tag with name is description. So, what you need to do is find this tag and take the content. For Sample:

                                                                                  res = soup.find('meta', {"name":"description"})
                                                                                  print(res['content'])

You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
