I have installed django framework with Python 2.7 and created all the paths. The problem is that whenever I type
django-admin.py command
the file itself is opening up. I am using Windows 7 64 bit.
Thank you.

You need to type
python django-admin.py command
If you get an error saying 'python is not recognized as an internal or external command..' you also need to add the python path to your environment path.

The problem is that .py files are not associated with python, so it gets treated as a normal txt file. You can either:
python django-admin.py command
(and see #VladSchnakovszki answer for errors which might pop up with that command), Or configure the files by right clicking > Properties, then (under General options):
Point it to python.exe and tell it to associate all files with the same extension with python as well.
P.S. a personal recommendation: When working in a windows environment I've had a good experience with installing ActiveState Python. It automatically sets the required paths, and also installs pip and other goodies that you'll probably need along the way (don't be scared of the priced version, there's a free community version too).

I've been looking forward to downloading the command-line interface for "Shodan".
On the website they say that i basically have to type "pip install -U --user shodan" in my cmd, so i did multiple times and it now says that the requirement are already satisfied, which feels normal since i did it multiple times trying to fix said problem.
Now the problem is, next step is to basically type "shodan" in the cmd, problem is it says 'shodan' isn't recognized.
What am i supposed to do ! :(
You need to add the path of the scripts to your system PATH variable:
It is something like this:
C:\Python38\Scripts
When you run pip install, it installs an exe file under the Scripts folder of your python installation. You should add this path to the PATH variable as described in the link. This makes the exe available in the terminal.

All the time that I've worked with python and anaconda, I have never wondered how actually virtual envs are useful except for version controlling. When I looked it up, I found a lot of articles on how to create and use custom envs, but not exactly why they are so awesome. Why is it dangerous to install new libraries into the original installation? Are virtual envs useful for anything other than versioning?
PROS:
You can use any version of python you want for a specific environment without having to worry about collisions.
Your main python package directory does not get flooded with unnecessary python packages.
You can organize your packages much better and know exactly the packages you need to run.
Anyone can run your code on their machine.
Your project is easier to deploy.
Your application runs faster.
Ease of maintenance.
CONS:
storage space?

I am a complete, absolute beginner so please excuse my ignorance!
I have created my first 'coding project' using Visual Studio Code IDE in Python, here is a link to it below:
https://github.com/monicaneill/Projects/blob/master/guessinggame.py
Basically my question is how do I show this to others in a way that they can interact with it and not just look at a bunch of text? I'm really proud of my achievement and want other people to be able to play the game who might not have the likes of Visual Studio etc to run the code, is there any way I can do this so someone on say Facebook could open up a file and then run the game?
Thank you so much and apologies in advance if this is not the right place to ask this sort of question!
A python file needs the python runtime to be run. With the python runtime on your system, you can simply do, in your terminal-
> python guessinggame.py
(assuming guessinggame.py is on the same directory)
However, I assume you want people to be able to run the code without having the python runtime installed.
In that case, you need to compile your python code to an executable native binary. There are tools to aid in this process - perhaps the most straightforward tool is pyinstaller
Firstly, you need to install pyinstaller in your own system-
pip install pyinstaller
Now, in your terminal, you simply have to do-
pyinstaller guessinggame.py
(Make sure you're on the same folder where guessinggame.py is)
This will create a folder on the same directory that contains all the files needed to launch your script as well as an .exe (if you're on windows) - your friends will only need this folder and all they have to do is run the .exe
You can find more information about pyinstaller and how to make executables with it here
Search by flask -> documentation
I think this is more or less what you are looking for.

Please forgive my ignorance. I'm using Mint 18.1. I installed Python 3.6 from its source code but it failed.
if I enter python, version 2.7 runs.
if I enter python3, version 3.5 runs (both were preinstalled with my Mint)
if I enter python3.6, i get a 'command not found' error.
Then I found and followed Error Installing Python.
My question is how to do i set it up so python3.6 runs without having to enter $HOME/py36/bin/python in the terminal.
Thanks

NEVERMIND. got it. thanks a lot, guys.
You could add an alias in your shell's config file (.bash_profile or similar, if you're using bash) that points python3 to $HOME/py36/bin/python.
To do this, you need to find your shell configuration file (~/.bash_profile, ~/.bash_login, or ~/.profile) and edit it so that it contains an alias. Aliases take the form of newcommandname='oldcommandname -flags', so you want something like python3="$HOME/py36/bin/python". Note how there are no spaces around the equals sign, and double quotes, as that is required for this to work.
Alternately, you could add $HOME/py36/bin/ to your $PATH variable, so that your shell automatically looks there for binaries. You can do this by editing your shell configuration file like above to say PATH="$HOME/py36/bin/:$PATH". This makes your shell look here for executables before anything else; PATH="$PATH:$HOME/py36/bin/" will cause your shell to look for executables here after looking everywhere else. I don't recommend this, tbh; do the first one.
The best way to maintain several different versions of python is via conda, which allows you to create a variety of environments with different Python versions and packages. Conda is part of the Anaconda scientific Python distribution.

There are lots of tutorials on YouTube and the web.

Basic steps to develop python API in Unix environment [closed]

I am developing an API in Unix environment for virtual machines. Most of the modules are developed in python. I have few questions on this.
I have the file extension as abc.py . I would like to make this as a command. For example , "virtman dominfo [vmid]" should be the command syntax. Now I have to give "virtman.py dominfo [vmid]" to achieve this. So how can make this as a command?
I want to make this as an installable API, I mean to install through apt-get/ yum install. What are the steps I need to do to achieve this or some reference URL's would be helpful.
Inside the API I am using absolute path like '/root/virtman/manager/' . Consider running this API in any unix environment , how can I make this absolute path generic to any OS/machine. Or should I have to assume some location where the API will get installed and give that path everywhere?
I read lot of articles but I didn't get the clear picture,so any hints/suggestions would be helpful.
This seems like it's three questions in one, so I'll attempt to answer each in turn:
File Extensions
Python scripts don't need to have a .py extension in order to be run. For example:
#!/usr/bin/python
print("Hello, World!")
Save this as a file called hello and flag it as executable. You should be able to run it from a terminal window by entering ./hello
apt-get / yum
Different systems use different packaging systems. For example, Debian and derivatives such as Ubuntu use .deb files, while Red Hat and co. use .rpm instead (though Debian can load .rpm files via the "Alien" tool). Each is slightly different, so I can't really give you a "generic" answer - hopefully this should be enough to get you started: https://fedoraproject.org/wiki/How_to_create_an_RPM_package
Generic Paths
You should be okay if you stick to the usual /var, /etc, /tmp layout - see this Wikipedia page for details.
