See ipython (  It provides mostly what you want:

In [1]: for i in range(3):
   ...:     print i,
0 1 2

In [2]: print 'hello'

In [3]: exec In[1]
0 1 2

Readline history search is bound to Ctrl-P/N (type a few characters, then hit
Ctrl-P/N to get previous/next lines with those matching chars).  Ctrl-r search
is also configured by default.
