The -i flag can help with that. See man python.

       -i     When  a  script  is  passed as first argument or the -c option is
              used, enter interactive mode after executing the  script  or  the
              command.   It does not read the $PYTHONSTARTUP file.  This can be
              useful to inspect global variables or a stack trace when a script
              raises an exception.

So the below does what you want it to. Note that the -i flag needs to precede the -c otherwise it doesn't work.

 python -i -c 'import numpy'

Actually a better way would be to create a file containing import numpy as np and assign its name to PYTHONSTARTUP - preferably in .bashrc or any other shell script that is executed by starting shell (depends on the shell being used).
