Please, open a Coursera account at www.coursera.org . Some topics in our syllabus are based on free lectures at Coursera. Coursera sometimes provides you an online platform to run Python codes, but it is limited to specific courses only. You may need special instruction to enroll for free. Coursera also provides a specialization ( for example Deep Learning Specialization) in the specific topics. If you are not paying for certificates, you can freely enroll individual courses in the specialization.
