Rajeev,
If I understand correctly, you are worried about the way functions, factors
and symbols are ordered in an evaluated expression. Your example is the
expected behavior. When an expression is evaluated, sympy has to decide how
to order the symbols. The default ordering is alphabetical. With capital
letters first. For example if I set p = n*R*T/V (ideal gas law) the display
of the value of p will return: RTn/V as the sorting is done within the
parts of the expression (numerator and denominator). I believe there are
some options for adjusting this, but others will have to speak to that.
