Can't transfer command line argument to script

[ghost]

When using getopt in my script, I can't transfer arguments to it. For example:
ipython script.py --t tuples .

Returns the following warning:
Error in Arguments: "Ambiguous option '--t'; matches ['term_title', 'tkthread', 'tk']"

This makes it impossible to user ipython as interpreted for scripts that use getopt
