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.
import sys
>>python Test.py 2asd

You need to call like
Test.py -n 2asd

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