Writing your first program

Now, because we are starting from fresh, we need to understand how to write our first program and execute it. PowerShell comes pre-installed on a Windows machine. But we need to install Python by downloading it from the web ( https://www.python.org) and choosing the right version for your operating system. Once downloaded, it can installed just like any other application that is installed on a Windows machine.

On a Linux machine, the same holds true, but because of the .NET requirement, PowerShell will not be supported on Linux or Unix environments. Hence, if we are using a Unix or Linux environment, Python or Perl remain our preferences for scripting.

There are multiple Integrated Development Environments (IDEs) for both Python and PowerShell, but the default ones that come with these languages are also pretty helpful.

There are multiple versions of PowerShell and Python being used. When writing programs in higher versions, generally the backwards support is not very good, so make sure you note the users and environment before choosing a version.
In our case, we will be using PowerShell 4 and Python 3 onwards for writing programs. Some commands might not run in older versions of PowerShell and Python, and some syntax or commands are different in older versions.
