En esta secciĆ³n, instalarĆ”s Python y un editor de texto. En las clases anteriores de la especializaciĆ³n, esta fue una tarea opcional, pero en esta clase es el primer requisito para comenzar. A partir de este momento, dejaremos de usar el ambiente de calificaciĆ³n Python basado en un navegador ya que el ambiente de Python basado en un navegador (Skulpt) no es capaz de ejecutar los programas mĆ”s complejos que desarrollaremos en esta clase.

Frequently asked questions
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
You will be eligible for a full refund until two weeks after your payment date, or (for courses that have just launched) until two weeks after the first session of the course begins, whichever is later. You cannot receive a refund once youāve earned a Course Certificate, even if you complete the course within the two-week refund period. See our full refund policy.
