Example details

Let us now walk through the example, line by line, to understand how it achieves the desired result of optimizing the indicated model.

The example begins by importing Gurobi functions and classes:

import gurobipy as gp
from gurobipy import GRB
The first line makes all Gurobi functions and classes available through a gp. prefix (e.g., gp.Model()). The second makes everything in class GRB available without a prefix (e.g., GRB.OPTIMAL). You can also start a program with from gurobipy import * to remove the need for the gp. prefix, but if your program uses multiple Python modules it is usually preferred to access each through its own prefix.

In order for these commands to succeed, the Python application needs to know how to find the Gurobi functions and classes. Recall that you have three options for installing them.
