So we have a python code that we execute on the command line with some arguments py code.py -p1 a -p2 b. Now we need to pass a date as an argument using a function, is there any way to write something like py code.py -p1 a -p2 b -p3 datetime.date.now().

My boss is awsking if we can do this but i have searched and found nothing. Thanks in advance for any answer.

No you cannot. Your shell is not executing python commands.

You can however use your shell capabilities to generate the date, for example with sh/bash:

py code.py -p1 a -p2 b -p3 $(date ' %Y-%m-%d')

Would launch the command:

py code.py -p1 a -p2 b -p3 2023-01-12

Another possibility is to pass now as parameter and to handle it in your script.

CodePudding user response：

You can, but beware that it's a big security risk. It will run any code entered at the command line.

text = eval(parameter)
