Python

format number into hexadecimal representation with padding zero to have a nice output:

print ("ID: 0x{:0>2x}".format((123))) # '0' padding with zeros, '>' right align, 'x' hexadecimal

some file handling:

fPath = r'file.txt'
with open(fPath,'r') as f:
    fContent = f.readlines()

reverse a string:

"Hello World!"[::-1]

let start powershell in the right python environment:

conda init powershell

Powershell

startMe.bat:

starts the powershell and directly jumps into a defined directory

powershell.exe -noexit -command "cd d:\temp"

shorten the command prompt via profile settings

(e.g. C:\Users\username\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1

function prompt {'PS ' + $(Get-Location | Split-Path -Leaf) + ">"}
