I have a lot of modules to import before running each script. But the modules i am importing is same in all the scripts. In case of debugging i have to change some code in one or more modules and again run the script. So each time python imports all the modules from the starting. Is there anyway that i skip importing of modules that haven't modified?
You can reload particular modules with reload function, like this
reload(math)

I have a python file with no argparse implementation in its __main__, yet, I'm interested in having a look at the functions and modules implemented in it from the commandline. I'm tempted to write a function to perform such exploration but I wanted to find out first whether this is already available.
EDIT 1: to make it more concrete, I'm interested in names of functions and classes + their docs.
You may be looking for a tool like python-fire.
From the repository:
Python Fire is a library for automatically generating command line interfaces (CLIs) from absolutely any Python object. [...] Python Fire helps with exploring existing code or turning other people's code into a CLI.
It is available as a package on pip.

Before you get confused, I am going to compile it with the auto-py-to-exe module after, its just the source code is in python. How do I do this?
If Python is not installed you wouldn't even be able to run a script to check if it's installed.
I'm pretty sure there isn't from inside the Python script. Because the interpreter isn't installed, so it'll never be able to understand HOW to execute the script at all.
You'll have to check outside in whatever is initiating the Python script and the compilation (bash script?) and do it there.

I want to convert a .py file into a multiplataform (Windows, Linux,..) onefile (without librarys or other folders) executable file for using it without a Python installation.
PyInstaller has the option to create a one-file application, just use the "-F" or "--onefile" argument when using it. I have never tried it on Linux though, on Windows I think it works.

I was wondering the purpose of runpy module in Python and how does it help in day to day development of the Python user community?
Can someone please explain the necessity, usage and advantages of runpy module in python?
The docs say:
The runpy module is used to locate and run Python modules without importing them first. Its main use is to implement the -m command line switch that allows scripts to be located using the Python module namespace rather than the filesystem.
You can run a python module like this:
python -m SimpleHTTPServer 8000
The runpy module enables this functionality. It may not be useful outside of this context.

I have tried using pythonw and this only works if I drop and drag the file onto it. I remember reading somewhere there is a way to keep this from happening in the code but I can't find it. Thanks in advance.
To run it with pythonw.exe just give your file a .pyw extension.
