8. Venture

The purpose of the category challenge is to create one thing that’s tangible and helpful utilizing Python file dealing with/ Python-SQL connectivity. This must be performed in teams of two to a few college students and must be began by college students not less than 6 months earlier than the submission deadline. The purpose right here is to discover a actual world downside that’s worthwhile to resolve.

College students are inspired to go to native companies and ask them concerning the issues that they’re going through.

College students might be extraordinarily artistic right here. They will use all kinds of Python libraries to create consumer pleasant purposes akin to video games, software program for his or her faculty, software program for his or her disabled fellow college students, and cell purposes, after all to do a few of these initiatives, some further studying is required; this must be inspired. College students ought to know the best way to train themselves.

The scholars must be sensitised to keep away from plagiarism and violations of copyright points whereas engaged on initiatives. Academics ought to take vital measures for this.
