Solve: Normalize the output format for one or multiples solutions.

[latot]

Hi, basically the title, examples:

>>> solve([Eq(y+x,1), Eq(x-y, 1)])
{x: 1, y: 0}
>>> solve(Eq(2*x,1))
[1/2]

ideal to:

>>> solve([Eq(y+x,1), Eq(x-y, 1)])
{x: 1, y: 0}
>>> solve(Eq(2*x,1))
{x: 1/2}

Thx. Cya.

You can set dict=true

In [1]: solve(Eq(2*x,1), dict=true)
Out[1]: [{x: 1/2}]

In [2]: solve([Eq(y+x,1), Eq(x-y, 1)], dict=true)
Out[2]: [{x: 1, y: 0}]

solveset

In [23]: solveset(Eq(2*x,1))
Out[23]: {1/2} 

In [24]: nonlinsolve([Eq(y+x,1), Eq(x-y, 1)], [x, y])
Out[24]: {(1, 0)}

In [25]: nonlinsolve([Eq(y+x,1), Eq(x-y, 1)], [y, x])
Out[25]: {(0, 1)}  # always FiniteSet of tuple(s)

Hi, this is only examples, and the idea its can set more than one eq, when solveset support it i think it will be fine, this examples don't are restricted for linear systems.

The focus here its, don't play with the output, choose one type of output and respect it, its very umconfortable start handle this manually, think when we use this for some work we use this automatically, so normally we can't control the input eqs and the requested vars, so play with the output its a bad idea.

i know use dict or set, but i think have a normal return should choose some standard format.
