Actually, isympy must depend only on python-sympy.  If python3-sympy is 
installed and python-sympy is not, then isympy fails, because of this:

    $ head -n 1 /usr/bin/isympy
    #!/usr/bin/python

One might create a isympy3 package, but this is a different issue from 
the one concerning the present bug report.
