What programming languages should a theoretical condensed matter physicist learn?

I have a question: What programming languages should a theoretical condensed matter physicist learn? I know there are the old staples of C and Fortran, but surely there are better languages for less-heavy-duty applications. I understand using C for supercomputing since computing time is the primary concern and C is optimized for efficiency. But I have heard that scripting languages like Python and Perl are easier to use for lightweight calculations. These dialects are known for emphasing programmer usability over computational efficiency.
