    copied!<p>I am a beginner python programmer, and I am working on a selenium project in python 2.7. </p> <p>I have a generic scraper script, that basically outlines what I want to do with all the websites that I visit. However, because of the nature of the data that I want to grab, I can't run the same code on each site-- each site needs to run it's own individual code. </p> <p>I have attempted to solve this by importing inside of an if statement, and this is the solution I came up with: </p> <pre><code>site = False if source_website == "Website A": from website_a import * site = True elif source_website == "Website B": from website_b import * site = True else: print "This is not an acceptable website!" if site == True: # main code block driver = driver_setup(chrome) driver.get(source_website_URL) stuff_to_save = do_some_stuff(driver) xml_file(stuff_to_save) driver.quit() </code></pre> <p>where the <code>website_a</code> and <code>website_b</code> modules both have functions named <code>do_some_stuff</code>, and they do stuff specific to the website that they're on. Now, this seems to work, for the most part. I also seem to be able to extend functionality to any number of websites, given that I program a module called <code>website_c</code> with the function <code>do_some_stuff</code>, and add that to the conditional import.</p> <p>So, my question is, is this a good idea? Is there a better way to do something like this?</p> <p>I have literally never seen anyone wrap import statements inside of if statements like this-- and generally, if no one seems to do it, there's usually a good reason why. </p>
