LearnLab Learning Terms
The learning service
LearnLab by Excel Keys provides free self-paced Python and SQL lessons, sample exercises, quizzes, projects and browser practice. No learner account or payment is required in this release. Lessons introduce practical topics; they are not an exhaustive language reference or a promise of employment, exam success or professional competence.
Using the examples
Use fictional data, respect other people’s rights, and avoid entering passwords, private records or harmful content in practice windows. Browser execution and package support have limits. Independently test any example before adapting it to a real application. External libraries remain subject to their own licences.
Course progress and answer help
Each course tracks 32 steps locally. You may solve the challenge and quiz yourself or use Check answer to study a worked solution and continue. Projects are available as further practice; the course-completion record does not assert that an external examiner assessed your projects. Browser records and imported backups are not a tamper-proof identity or examination system.
Certificates
A certificate is available when the local record shows all 32 steps in that course complete. You supply the displayed name; older records may require confirmation of a date. Python and SQL have separate course titles and emblems. Read the certificate policy. This is a non-accredited completion acknowledgement, not a degree, government certificate, independent identity verification, job licence or affiliation with Python/SQL organisations.
Content, branding and sharing
Excel Keys branding and original site content belong to their respective rights holders. You may download and share your own completion certificate accurately. Do not alter a certificate to misrepresent its issuer, course, recipient or meaning, or imply an accreditation that is not offered. Third-party logos and open-source components retain their respective ownership and licence terms.
Availability, changes and data
The service may change or be temporarily unavailable. Browser data can be lost and offline resources may need to download again. Keep your own progress backup and downloaded certificate. Any future advertising should be clearly labelled and covered by applicable privacy/consent information; free learning is not a permanent no-advertising promise.
Limits and questions
Learning materials and browser-generated records are provided for educational use. They do not replace checking results for your own requirements. Nothing in these terms excludes rights or duties that cannot lawfully be excluded. For corrections, access issues or questions, contact info@excelkeys.in. The wider site’s terms may cover services outside LearnLab.
