Re: Regarding Regex timeout behavior to minimize CPU consumption
Hi, Timeout: no idea. But check out re.compile and re.iterfind as they might speed things up. I often compile a regex once upon import, then use it in functions On 27 Nov 2020 13:33, Shahique Khan wrote: Hi Team, I have noticed if our regex sometimes does not give a result and on that time regex took more time in returning response (empty response). My Question is can we set a timeout parameter (in seconds/millisecond) with re.find or anywhere in code to avoid CPU consumption if regex takes more time in execution. Below is the example, which take more time in execution: (in this case can we set timeout to kill the execution to avoid CPU consumption) regex = r'data-stid="section-room-list"[\s\S]*?>\s*([\s\S]*?)\s*' \ r'(?:class\s*=\s*"\s*sticky-book-now\s*"|\s*|id\s*=\s*"Location")' rooms_blocks_to_be_replace = re.findall(regex, html_template) Please help me, I will be very thankful for this.

Re: Bot
Try Selenium (preferred) or Mechanize. I recently used Selenium with Chrome for automated unittests of a web app, including a login screen. You could fire up the selenium script in a cron job at the desired time.

I was using datetime.now().isoformat('T', 'seconds')
Not 100% sure, but the strings seemed to be 2hrs off. Could it be that
this Linux server was using the wrong time zone?

I was aware of running it in debug mode, but I was looking for domething to use in production. I checked how werkzeug does it, see line 160: https://github.com/pallets/werkzeug/blob/master/src/werkzeug/_reloader.py I'll study this in more detail tomorrow.

Hot reload Flask app?
Hi, I would like to create a "/reload" view in my Flask app, so I could easily and safely reload it when code, templates etc change. Similar to what happens when running the app with the debug server. I am using Nginx and Gevent on a recent Ubuntu system with Python 3.6. My strategy would be to gracefully stop Gevent [1], then do os.kill(os.getpid(), signal.SIGHUP). I have not yet tried this (not working today!). Just wondering if there are best practices. Thanks!

If you want to clean up the original code you can use a csv.reader csv_reader = csv.reader(csv_file) fieldnames = next(csv_reader) for row in csv_reader: print(row[1]) but my assumption was that > print(line[csv_reader.fieldnames[1]]) wasn't the final code, only something to get things working. > Or maybe: > cols = csv_reader.fieldnames > print( [[val for val, col in zip(record, cols) if col in ['somecol']] > for record in csv_reader]) > ? This is ugly and complex. It can be simplified to num_rows = sum(1 for _ in csv_reader) print([["somecol"]] * num_rows) Why would you want to this? ===》 I thought the OP wanted to take a subset of the columns in his data. In my example I intended to select one column, but with code that cpuld easily be extended to a selection of multiple columns.
