Command line argument with python

Command line argument with python



I am trying to execute below python script. But getting below issue after execution.



Code


#!/usr/bin/python



def Student(Student_Id):


msg = Student_Id + "." +

return msg



Error


C:UsersDesktop>Test.py 2asd



After an investigation found that argument which I am passing through the command line is considered as Null.





you could import sys in your script and the first item in the comman line can be read in script as 'a = sys.argv[1]', where a is basically 2asd when read using the command >>python Test.py 2asd

You need to call like


Test.py -n 2asd





Why? Please add more information

There's no such requirement? Calling "Test.py 2asd" will put "2asd" in sys.argv[1].

The original question had optparse with an add_argument -n and the OP was calling Test.py 2asd without doing -n. Hence, the answer. See stackoverflow.com/posts/52152122/revisions
