A simple example

# Solve the following MIP:
#  maximize
#        x +   y + 2 z
#  subject to
#        x + 2 y + 3 z <= 4
#        x +   y       >= 1
#        x, y, z binary

import gurobipy as gp

# Create a new model
m = gp.Model()

# Create variables
x = m.addVar(vtype='B', name="x")
y = m.addVar(vtype='B', name="y")
z = m.addVar(vtype='B', name="z")

# Set objective function
m.setObjective(x + y + 2 * z, gp.GRB.MAXIMIZE)

# Add constraints
m.addConstr(x + 2 * y + 3 * z <= 4)
m.addConstr(x + y >= 1)

# Solve it!
m.optimize()

print(f"Optimal objective value: {m.objVal}")
print(f"Solution values: x={x.X}, y={y.X}, z={z.X}")
