It crashes because you are accessing argv[1] which would hold a command line argument (other than the program’s name) if there was one. You should check whether argc is greater than 1. Why greater than 1? Because the first command line argument is the name of the program itself. So argc is always greater than … Read more
The default return of the method will be None. If you perform the following: res = output() and print out res, it will be None. By default, None is always returned when not specifying a return. >>> def output(): … print “Hello, world!” … >>> res = output() Hello, world! >>> res >>> type(res) <type … Read more

Let’s say you’ve a command line file_matcher program, how are you going to use it? well, you’ve to pass the file names to the program that you want to match. You can not hard code them(means, you can not write the file names in the code file). cause if you hard code them, then you’ve … Read more
The lenght of the array is limited to the arguments used. So if you have 3 arguments (java Program 1st 2nd 3rd) then you will not be able to access more than that (e.g. args[3] for the 4th) To assign a new value to an existing argument is possible. But I have no idea for … Read more

You contradict yourself in the question by stating you need to use constants yet ask how to use variables – they’re diametrically opposed as far as the ideas go. One is constant the other is variable. Currently you use literals to construct your inputs, so you can swap them out easily enough. If you want … Read more
Since you say you know Java, why not write a Java program that provides the GUI, and then runs the python script? I’m pretty sure Java can run external programs solved Python – Make a GUI for an existing script [closed]
You’re giving it a classpath, but not the name of the class to execute. You’re also only including the jar file on your classpath – not the directory containing your class file. So to repeat my answer from the other question: java -cp .;cs2.jar CB (Run from the directory containing both CB.class and cs2.jar.) 1 … Read more

When you use ls, you are reading a directory file, not actually looking in a directory. Every directory listing contains an entry for the present/current directory, as well as its parent directory, just as you would expect to also see listings for sub/child directories in any directory listing.
