Class 12 Computer Science Syllabus 2022-23: Practical List

Python Programming

  • Read a text file line by line and display each word separated by a #.
  • Read a text file and display the number of vowels/consonants/uppercase/lowercase characters in the file.
  • Remove all the lines that contain the character ‘a’ in a file and write it to another file.
  • Create a binary file with name and roll number. Search for a given roll number and display the name, if not found display appropriate message.
  • Create a binary file with roll number, name, and marks. Input a roll number and update the marks.
  • Write a random number generator that generates random numbers between 1 and 6 (simulates a dice).
  • Write a Python program to implement a stack using the list.
  • Create a CSV file by entering the user-id and password, and read and search the password for the given user-id.

Database Management

  • Create a student table and insert data. Implement the following SQL commands on the student table:
  • ALTER table to add new attributes / modify data type/drop attribute o UPDATE table to modify data
  • ORDER By to display data in ascending/descending order o DELETE to remove tuple(s)
  • GROUP BY and find the min, max, sum, count, and average
  • Similar exercise may be framed for other cases.
  • Integrate SQL with Python by importing suitable module.

Computer Science Class 12 Syllabus 2022-23: Project

The aim of the class project is to create something that is tangible and useful using Python file handling/ Python-SQL connectivity. This should be done in groups of two to three students and should be started by students at least 6 months before the submission deadline. The aim here is to find a real world problem that is worthwhile to solve.

Students are encouraged to visit local businesses and ask them about the problems that they are facing. For example, if a business is finding it hard to create invoices for filing GST claims, then students can do a project that takes the raw data (list of transactions), groups the transactions by category, accounts for the GST tax rates, and creates invoices in the appropriate format. Students can be extremely creative here. They can use a wide variety of Python libraries to create user friendly applications such as games, software for their school, software for their disabled fellow students, and mobile applications, of course, to do some of these projects, some additional learning is required; this should be encouraged. Students should know how to teach themselves.The students should be sensitised to avoid plagiarism and violations of copyright issues while working on projects. Teachers should take necessary measures for this.
