You can use pure python modules from jython. You can't use modules that are implemented in C. To use modules from your pip installs, you need to add the sys.path of python to that of Jython as Jython does not automatically pick up the PYTHONPATH informationJython 2.5 introduced the JYTHONPATH ...

You connect and use a python module on the remote computer over SSH, as SSH only provides limited functionality so calling the module isn't possible.You can call a script on the remote server and run that as a way of getting around this problem. To get a result from the ... Read More

There is no straightforward way to do this. But it is possible to run a Python program and parse the output. You can execute any shell command using the function system (cmd, flag). The second argument is optional. If it is present, the output of the command is returned by ... Read More

You can use "Sandboxed Python". A "Sandboxed Python" would let you permit or forbid modules, limit execution slices, permit or deny network traffic, constrain filesystem access to a particular directory (floated as "/"), and so on. It is also referred to as RestrictedExecution. There are many ways to implement sandboxing ... Read More

Namespace is a way to implement scope. In Python, each package, module, class, function and method function owns a "namespace" in which variable names are resolved. When a function,  module or package is evaluated (that is, starts execution), a namespace is created. Think of it as an "evaluation context". When ... Read More

Yes, a function call (any function call, not just recursive ones) creates a new namespace. BUT, when given as parameters, OBJECTS are passed by reference.So, the new namespace get its own copy of this reference but it still refers to the same object as in the calling function, and if ... Read More

It is a bad idea to be importing everything from a Python package as a package is not a super-module -- it's a collection of modules grouped together. So you should just import what you need in that file. Also importing everything from package into your global namespace is going ... Read More

I want to know what all standard exceptions are there in python. Where can I find a list of standard python exceptions?The standard python exception list for programmers is available athttps://docs.python.org/3/library/exceptions.html

With a 64-bit Python installation, and 64 GB of memory, a Python 2 string of around 63 GB should be quite feasible. If you can upgrade your memory much beyond that, your maximum feasible strings should get proportionally longer. But this comes with a hit to the runtimes.With a typical ... Read More

We see that most exceptions have their names ending in word ‘error’ pointing that they are errors which is the meaning of exceptions anyway.Errors in restricted sense are taken to mean syntax errors in python and those errors occurring at run time are called exceptions. As we know that classes ... Read More
