Choose Argument position for scipy minimise

I have a function defined as follows

def function(a, b, c, d):
    ### some calculation
    return output

I was to use scipy.minimise to minimize the output with respect to variable a alone. Is there a way to tell it to just solve for the first variable (while keeping b, c and d constant).

Thanks.

From docs:

The objective function to be minimized: fun(x, *args) -> float

and

argstuple, optional: Extra arguments passed to the objective function and its derivatives (fun, jac and hess functions).

So simply use a wrapper (or rewrite the definition and the first lines in your function):

def functionWrapper(x, args):
    a = x
    b,c,d = args
    return function(a,b,c,d)

And the minimization call

minimize(functionWrapper,initialGuess,(bValue,cValue,dValue,));

where bValue,cValue,dValue are the constant values for the coefficients.
