Use the symbols convenience function. e.g. (in isympy):

In [1]: from sympy import symbols

In [2]: a, b, c, x = symbols('a b c x')

In [3]: a
Out[3]: a

In [4]: Force, Mass, Acceleration = symbols('Force Mass Acceleration')

In [5]: Force
Out[5]: Force

In [6]: alpha, beta, gammas = symbols('alpha beta gamma')

In [7]: alpha
Out[7]: alpha

On Linux that last line would show the actual Greek letter α but this
is Windows and sympy knows that I'm using a rubbish console.
