We have this:
In [1]: print_tree(x**2+x**3)
Add: x**3 + x**2
+-Pow: x**3
| +-Symbol: x
| | commutative: True
| +-Integer: 3
| real: True
| nonzero: True
| infinitesimal: False
| commutative: True
| zero: False
| nonpositive: False
| positive: True
| noninteger: False
| negative: False
| nonnegative: True
| hermitian: True
| complex: True
| bounded: True
| rational: True
| unbounded: False
| integer: True
| imaginary: False
| finite: True
| irrational: False
+-Pow: x**2
+-Symbol: x
| commutative: True
+-Integer: 2
real: True
nonzero: True
finite: True
commutative: True
infinitesimal: False
nonpositive: False
positive: True
noninteger: False
zero: False
negative: False
hermitian: True
complex: True
bounded: True
rational: True
unbounded: False
integer: True
imaginary: False
nonnegative: True
irrational: False
and also this:
In [9]: print_python(x**2+x**3)
x = Symbol('x')
e = x**3 + x**2
