PuLP is an LP modeler written in python. PuLP can generate MPS or LP files and call GLPK, COIN CLP/CBC, CPLEX and XPRESS to solve linear problems.

Use LpVariable() to create new variables. ex:
>>> x = LpVariable("x", 0, 3)
to create a variable 0 <= x <= 3
Use LpProblem() to create new problems. ex:
>>> prob = LpProblem(
Combine variables to create expressions and constraints and add them to the problem. ex:
>>> prob += x + y <= 2
If you add an expression (not a constraint, e.g. prob += 4*z + w), it will become the objective.
Choose a solver and solve the problem. ex:
>>> prob.solve(GLPK())
You can get the value of the variables using value(). ex:
>>> value(x)
Exported Classes:
* LpProblem  Container class for a Linear programming problem
* LpVariable  Variables that are added to constraints in the LP
* LpConstraint  A constraint of the general form
a1x1+a2x2 ...anxn (<=, =, >=) b
* LpConstraintVar  Used to construct a column of the model in columnwise modelling
Exported Functions:
* value()  Finds the value of a variable or expression
* lpSum()  given a list of the form [a1*x1, a2x2, ..., anxn] will construct a linear expression to be used as a constraint or variable
* lpDot() given two lists of the form [a1, a2, ..., an] and [ x1, x2, ..., xn]will construct a linear expression to be used as a constraint or variable
