PowerShell

[Xander Cage]

I’m pursuing a python course and trying to run a Python script in PowerShell. While using the sys module I stumble upon the problem of getting the return value of a PowerShell function. The function in question is Date -f ‘dd\/MM\/yyyy’ that returns 14/03/2019 and I’d like that value to be used as an argument in the Python script. I’ve been able so far to get the literal arguments from the command line, e.g. text.

I’m guessing that date is some sort of shortcut for Get-Date.  (I hadn’t seen it before, but it only took a second to see what it’s doing).

The key here is that date is producing a DateTime object.  Now — when you tack on the -f (format string operator), you are converting that DateTime to a String.

PS C:\> date
Thursday, December 3, 2020 9:56:30 PM
PS C:\> (date).GetType()
IsPublic IsSerial      Name           BaseType
-------- --------      ----           --------
    True     True  DateTime   System.ValueType
PS C:\> date -f 'dd/MM/yyyy'
03/12/2020
PS C:\> (date -f 'dd/MM/yyyy').GetType()
IsPublic IsSerial    Name       BaseType
-------- --------    ----       --------
    True     True  String  System.Object

So, if you want to input it into your python function, get rid of the -f operator, it’s completely unnecessary at this point.

Good luck!

Why are you doing this? Python is Python, PowerShell is PowerShell run python scripts in python and PowerShell scripts in powershell

from datetime import datetime
now = datetime.now() # current date and time
strdate = now.strftime("%d/%m/%Y")
print("date and time:",strdate)
