   • process spawning in python

     Top Answer

     Answered Nov 19, 2013 · 1 votes

     The only 'more control' that os.spawn gives you over subprocess is the mode argument - but on Unix, this can only control whether the call blocks waiting for the subprocess to finish, which is also doable with subprocess.

     In any case, the best way to turn your command into a list of arguments is to use the shlex.split

     function, as recommended by the subprocess docs:

     command = 'sudo start service/new_sevice db=tmp'subprocess.call(shlex.split(command))-

     If you really want to use os.spawn* family (and you probably don't), you can also use shlex.split - it gives its result in the form subprocess expects which differs slightly from the form os.spawn* expect, but you can get around this easily enough using the spawnl* variants and Python's argument unpacking:

     os.spawnlp(os.P_WAIT, *shlex.split(command))-

   • process not starting in python

     I'll guess you're using windows...

     Put your initalisation code in an if __name__ == '__main__': block:

     import serialfrom multiprocessing import Process-ser=serial.Serial('COM8',115200)c=" "out=" "def pi(): print ("started") out=" " while 1: # loop contentsdef man(): while(1): # loop contentsif __name__ == '__main__': p1=Process(target=pi,args=()) p2=Process(target=man,args=()) p1.start() p2.start() p1.join() p2.join()

     On windows, to work around the lack of fork() each newly started subprocess has to import the __main__ module, so you'll run into an endless loop of spawning processes unless if you don't protect your initialistion code.

     output_word = output_word.decode()-

     will convert the bytes to a string.

     UPDATE

     this is the last state from the script in the chat (still far from perfect...):

     import requestsfrom lxml import htmldef define_word(word): response = requests.get( "http://dictionary.reference.com/browse/{}?s=t".format(word)) tree = html.fromstring(response.text) title = tree.xpath('//title/text()') print(title) defs = tree.xpath('//div[@class="def-content"]/text()') # print(defs) defs = ''.join(defs) defs = defs.split('\n') defs = [d for d in defs if d] for d in defs: print(d)define_word('python')

   • Define stubs in python

     Top Answer

     Answered Sep 29, 2021 · 2 votes

     So let's start simple, you got some statement, let's parse it into simple parts and connect it into the Python world.

     • Define stubsnoun Something cut short or arrested in development. (source)
     • for the functions get_user_num() and compute_avg()The keyword def introduces a function definition. It must be followed by the function name and the parenthesized list of formal parameters. The statements that form the body of the function start at the next line, and must be indented. (source)
     • Each stub should printCheck how to output something with Python to the console.
     • followed by a newlineAs in do not make two FIXME lines collapse onto each other like this: FIXME: somethingFIXME: something else .the Unix end-of-line convention '\n', the Windows convention '\r\n', and the old Macintosh convention '\r'...(source)
     • and should return -1
     • Each stub must also contain the function's parameters.Undefined anywhere. So either use something you'd normally use for a let's say maths function or likes
     • Sample output with two calls to get_user_num() and one call to compute_avg() : ...This is how the final program should behave once executed. A function is called by first being ensuring it's been defined previously, then writing its name + () e.g. func() .Judging by the undefined func arguments and two related functions, you might want to connect the two functions either directly or with an intermediary item holding the result.

     After these steps you should be able to create the final program. Do not try to create it at once, utilize the bullet points as small steps and always check if the file still works (executes properly). Create multiple files (copy-paste) when necessary.

     Nobody cares how it looks like while developing. You're learning, you'll become better eventually.

    How does bagging work?

    • Bagging is provided via the BaggingRegressor and BaggingClassifier classes. Both models operate the same way and take the same arguments that influence how the decision trees are created. Randomness is used in the construction of the model. This means that each time the algorithm is run on the same data, it will produce a slightly different model.

    Bagging is an ensemble algorithm, in that multiple models are combined to produce a net result that outperforms any of the individual models. This approach can significantly reduce the amount of variance in the prediction results. Bagging was first developed in 1994 by Breiman et al 1.
