'Return object `type` assumptions.
For example:
Symbol(\'x\', real=True)
Symbol(\'x\', integer=True)
are different objects. In other words, besides Python type (Symbol in
this case), the initial assumptions are also forming their typeinfo.
Examples
>>> from sympy import Symbol
>>> from sympy.abc import x
>>> x.assumptions0
{\'commutative\': True}
>>> x = Symbol("x", positive=True)
>>> x.assumptions0
{\'commutative\': True, \'complex\': True, \'hermitian\': True,
\'imaginary\': False, \'negative\': False, \'nonnegative\': True,
\'nonpositive\': False, \'nonzero\': True, \'positive\': True, \'real\': True,
\'zero\': False}'

@property
def assumptions0(self):

    return {}
