I use Powershell for everyday scripting, text manipulation, simple REST api testing and other tasks. My choice to use Powershell was primarily based on availability. At the time (2010), every company machine I was using or going to use was Windows and guaranteed to have Powershell. Python was an option but not guaranteed to be installed on every machine. The choice was not based on ease of use, flexibility or support.
For me, Python and PowerShell are different animals. Python is a programming language, and easy to learn, a good choice. Powershell is more of a scripting language and shell. Once I write something in Python, then I install or run, or configure the host, using PowerShell. Both Python and PowerShell work fine on Windows 10.
