How To Pass A Variable As A Command Line Argument In Ipython?

For example, I have a Python module and a iPython module, cmd.py import sys print sys.argv test.ipynb for i in range(5): %run cmd.py i When I run test.ipynb, it just print ['c

Solution 1:

the shell mode interprets everything literally (else cmd.py would be evaluated as well). I would just do:

for i in range(5):
   %run cmd.py $i

For simple cases, you can alternatively prepend $ to a variable name
