get_constraints | Helper function to get the enabled constraints out of the portfolio object When the v1_constraint object is instantiated via constraint, the arguments min_sum, max_sum, min, and max are either specified by the user or default values are assigned. These are required by other functions such as 'optimize.portfolio' and 'constrained_objective' . This function will check that these variables are in the portfolio object in the constraints list. We will default to 'min_sum=1' and 'max_sum=1' if leverage constraints are not specified. We will default to 'min=-Inf' and 'max=Inf' if box constraints are not specified. This function is used at the beginning of optimize.portfolio and other functions to extract the constraints from the portfolio object. We Use the same naming as the v1_constraint object.
