Python Pandas Dataframe - Cut specific part of string, when length to long

Asked 2021-May-23 at 09:39

I'm working on a web-crawler in python for my tennisclub to save game-result, ranks etc. from a webpage in my database (to then show it on my own website). Works just fine, I get tables like this:

However, some team-names are way to long to output them nicely on my website (especially when two clubs together).

My question is: how can I cut everything behind the "/" with pandas if a string reaches a certain length, like 34.

My code so far (with other, working, changes to the crawled information):

ANSWER

Answered 2021-May-23 at 09:29

Since you mentioned that length would be more than 34 only if there are more than 1 team, so simple solution would be to check the length first, if more than 34, then do a split at / and get the first team:

QUESTION

How to run a python script using selenium chromedriver in background (Windows)?

Asked 2020-Aug-25 at 18:46

I am trying to make a background web-crawler in python. I have managed to write the code for it and then I used the pythonw.exe app to execute it without any console window. Also, I ran ChromeDriver in headless mode.

The problem is, it still produces a console window for the ChromeDriver which says $ DevTools listening on ...some address.

How can I get rid of this window?

...

ANSWER

Answered 2020-Aug-25 at 18:46

Even if you make the script as .pyw, when the new process chromedriver.exe is created, a console window appears for that. There is an option to turn on the option CREATE_NO_WINDOW in C#, but there is not one yet in Python bindings for selenium. I was planning to fork selenium and add this feature myself.

Solution for now (only for Windows): Edit the selenium library

Go to this folder: C:\Users\name\AppData\Local\Programs\Python\Python38-32\Lib\site-packages\selenium\webdriver\common\ (The path till Python38-32 depends on your installation of python).

There will be a file named service.py, which you need to edit as follows:

Add the import statement at the top from subprocess import STDOUT, CREATE_NO_WINDOW
Now (maybe in the line numbers 72 to 76), you must add another option creationflags=CREATE_NO_WINDOW in the function subprocess.Popen(). To make it clear, see before and after versions of code below:

How to implement an async task queue with multiple concurrent workers (async) in dart

Asked 2020-Jul-14 at 10:20

My goal is to create a kind of web-crawler in dart. For this I want to maintain an task queue where the elements are stored that need to be crawled (e.g URLs). The elements are crawled within the crawl function which returns a List of more elements that need to be processed. Thus these elements are added to the queue. Example code:

page.$eval() selector only using visible element

I'm working with puppeteer at the moment to create a web-crawler and face the following problem:

The site I'm trying to scrape information off of uses Tabs. It renders all of them at once and sets the display-property of all but one tab to 'none' so only one tab is visible.

The following code always gets me the first flight row, which can be hidden depending on the date that the crawler is asking for.

ANSWER

Answered 2020-Feb-09 at 04:12

Instance methods are implicitly passed the instance as the first argument (self). That means crawler.crawl(web) gets turned into WebCrawler.crawl(crawler, web).

I'm not sure how to fix it since I'm not familiar with these modules, but I would guess that crawl is supposed to take an argument, since WebCrawler doesn't have a root method:

I see you fixed EC.presence_of_element_located((By.ID,{'class':'result-content'})) to be EC.presence_of_element_located((By.CLASS_NAME,'result-content')))

Next, you might have an issue with (depending where the browser is opened) of having to bypass/clicking a javascript that says you are ok and accept cookies.

But all that code seems to be an awful lot of work considering the data is stored as a json format in the script tags from the html. Why not just simply use requests, pull out the json, convert to dataframe, then write to csv?

There were a couple errors in the code, I've corrected below. You need to create a new ADODB.Stream object, or, ensure you close the previous object. Also, you should strongly type the variables wherever possible. I cleaned this up in a few spots.
