By "interpreter's namespace" I presume you mean not the C namespace of
CPython, but the namespace of the currently executing __main__ module.
There is no such command (other than sys.exit(8-)).  You have to
(carefully) delete one thing at a time:

# add something
a,b=1,2
dir()
#['__builtins__', '__doc__', '__name__', 'a', 'b']

import __main__
for w in dir():
  if w not in ['__builtins__', '__name__', '__main__']:
    delattr(__main__, w)

delattr(__main__, 'w')
delattr(__main__, '__main__')
dir()
#['__builtins__', '__name__']
# Assume __doc__ not really needed, but code may depend on these two.
