Example:

pyobject pystr = "python string "; pystr; ==> 'python string ' pyobject pyint = 2; pyint; ==> 2 pyobject pylst = list(pystr, pyint); pylst; ==> ['python string ', 2] pyint + pyint; ==> 4 pyint * pyint; ==> 4 pystr + pystr; ==> 'python string python string ' pystr * pyint; ==> 'python string python string ' python_eval("17 + 4"); ==> 21 typeof(_); ==> pyobject
