How to exec() a string like interactive python does?

If I start Python in interactive mode,
and I yype the commands,
'a=3', 'a', 'print a'
Then the output would look like:
>>> a = 3
>>> a
3
>>> print a
3
Now within an application I'd like to achieve exactly this behaviour
Meaning, that
- for assignments nothing is displayed
- for expressions the result of the exprission displayed
- and statements like print statements would be executed
The only thing, that I came up with is following code and that would
even print out results for 'a=3', where the normal interactive python would not echo any result.
for cmd in [ 'a=3', 'a', 'print a' ] :
try:
print('>>> ' + cmd)
exec('__rslt = ' + cmd)
if __rslt is not None:
print repr(__rslt)
except SyntaxError:
exec(cmd)
The result would look like:
>>> a=3
3
>>> a
3
>>> print a
3
>>>
Is There anything better?
