Python tutorial

Use CPLEX interactively in a Python session, or write an application using the Python API for CPLEX.

Design of CPLEX in a Python application
An application of CPLEX in the Python programming language uses Python objects.
Starting the CPLEX Python API
Use the script setup.py (supplied with the product) to get started with the CPLEX Python API on your system.
Accessing the module cplex
Invoke CPLEX in a Python session.
Building and solving a small LP with Python
