Yes there are ways to import Python modules without installing. If you are not able to install modules on a machine(due to not having enough permissions), you could use either virtualenv or save the module files in another directory and use the following code to allow Python to search for modules in the given module:>>> import os, sys >>> file_path = 'AdditionalModules/' >>> sys.path.append(os.path.dirname(file_path)) >>> # Now python also searches AdditionalModules folder for importing modules as we have set it on the PYTHONPATH.You can also use virtualenv to create an isolated local Python environment. The basic problem being addressed is ... Read More

Yes you can keep Python modules in compiled format. Python automatically compiles Python source code when you import a module, so the easiest way to create a PYC file is to import it. If you have a module mymodule.py, just do:>>> import mymoduleto create a mymodule.pyc file in the same directory. A drawback is that it doesn’t only compile the module, it also executes it, which may not be what you want. (however, it does compile the entire script even if it fails to execute the script). To do this programmatically, and without executing the code, you can use the ... Read More

How to Install two python modules with same name?

This is not possible with the pip. All of the packages on PyPI have unique names. Packages often require and depend on each other, and assume the name will not change. Even if you manage to put the code on Python path, when importing a module, python searches the paths in sys.path by order and stops at first match. So whatever module it finds first, it'll stop at that. You best bet is to copy all the code from the libraries to you codebase, change the module name of either and then import it.If you're importing modules with same name from ...
