run a python function with arguments

With the ncinfo command, I can view the contents of a netcdf file from a csh (Eg. ncinfo test.nc). The ncinfo command actually calls the python function here. My question is: How do I use the ncinfo function directly from a python shell?

I tried the

from netCDF4.utils import ncinfo
ncinfo()

but I can't figure out how to pass the filename 'test.nc' to the function. Any idea?

Edit: Based on the comments, I think the question now is

How to 'fake' an argument inside a python shell to feed a function which use getopt.getopt and sys.argv to accept arguments?

As Alan Leuthard and jez point out in the comments, one can manually modify sys.argv (didn't know it's mutable) before calling the function. So a working solution is

from netCDF4.utils import ncinfo
backup = sys.argv
sys.argv = ['','test.nc']
ncinfo()
sys.argv = backup
