1. This is a command line entry point. It means that if you execute the script alone by running python test.py at the command line, it will call unittest.main. This executes the test runner by discovering all classes in this file that inherit from unittest.TestCase. This is one of many ways to execute the unittest test runner.
2. Running Python Programming software on MS Windows 10S? From what I see on the Internet, Windows 10S will only run software purchased from the app store; i.e., software downloaded from the Internet or copied from an external drive will not work.

Welcome to a series on programming quantum computers. There's no shortage of hype around quantum computing on the internet, but I am going to still outline the propositions made by quantum computing in general, as well as how this pertains to us and programmers who intend to work with quantum computers, which we will be doing immediately in this series.

Lets call it hello.py. Open a command prompt, by pressing start, run and type “cmd” (in the text field) and press OK.

Learn how to run Python code?

You can execute Python code from the terminal or from a Python IDE. An IDE is a graphical environment that assitsts in software development.

Run Python Interactively

One of the ways to run Python code is by using the interactive shell (repl).
To start an interactive shell, open the terminal app or command line and type python enter.

By default it shows >>>, where you can type Python code. You can type any expression or statement.

It shows the output of your code immediately.

The downside of the interactive shell is, once you close the shell, your code is gone.
To quit interactive mode:

• presss Ctrl + d (Unix) or Ctrl + z (Windows)
• type quit() and press enter.

How to Run Python

You can run Python in the command line. Create the following code in a text editor:

Then save the file as hello.py. You must use the .py extension.

All Python programs are written in code, text files with lots of instructions. These are saved with the extension .py. A program made in Python can be one or more .py files.

Then, if Python is installed, you can run the script with this command:

You should see Hello World on the screen. If you see it, you just ran your first Python code!

Run in Terminal

Run Python on Linux

To run a Python program, you need to have Python installed. Start the terminal.
In the terminal, type the command below to test if Python is installed

Python installed?

Open a terminal and enter the directory of your program. The directory may contain more than one python (.py) file.

In the terminal type:

where file.py is the name of your program. If you have more than one file, the main program is often the name of the program itself;

Run Python on Windows

To run Python programs on windows, there are a few steps you need to do.

1. Save your code with the .py extension. Lets call it hello.py

2. Open a command prompt, by pressing start, run and type “cmd” (in the text field) and press OK.

3. Go to the directory of your Python file with the cd command.

4. Run the script with Python

5. If you get an error, like the one shown below:

then python is not in the path (environment variables). Make sure it’s included in your Windows environment variables.

Programiz Python Compiler

The easiest way to do that, is selecting a box in the installation.

If you have already installed Python, you can set the environment variable in the control panel.

Programs That Run Python

Run Python on Mac

You need Python installed on your Mac OS X system. On Mac the older Python 2 is often installed by default.

If you don’t have Python installed, open the Terminal app. Then install Xcode tools:

Install homebrew with this command:

Finally install Python, type the command:

Run Python code

Then you can run the command on your code:

You must be in the same directory as your file, or add the path.

or move into the directory:

Run from IDE

Sometimes an easier way to execute Python programs is using a Python IDE.

What is an IDE?

An IDE is a tool that assists in software development. Its a software program that has many features like:

• code coloring (syntax highlighting)
• file navigation
• quick search
• and much more.

In most IDEs, there’s a play button that instantly runs the Python program. In other words, in a Python IDE, you simply press the ‘play’ button.

PyCharm

The PyCharm IDE lets you run Python code with a single click. After creating the project, press the green play button in the right corner.

The image above shows the header of the program PyCharm, a Python IDE. The green play button can be used to start a program.

In PyCharm, you can also press “Run”, “Run ‘HelloWorld’”.
