Question

sys.arg[0] gives me the python script. For example ‘python hello.py’ returns hello.py for sys.arg[0]. But I need to know where the hello.py is located in full path.

How can I do that with python?

Answer 1

import sys
print(sys.path[0])

From the docs:

As initialized upon program startup,
the first item of this list, sys.path[0],
is the directory containing the script
that was used to invoke the Python
interpreter.
