Suggested 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 the name and roll number. Search for a given roll number and display the name, if not found display the 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 for 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
  • UPDATE table to modify data
  • ORDER By to display data in ascending/descending order
  • DELETE to remove tuple(s)
  • GROUP BY and find the min, max, sum, count, and average

A similar exercise may be framed for other cases. Integrate SQL with Python by importing suitable modules.

Suggested Reading Material

  • NCERT Textbook for COMPUTER SCIENCE (Class XII)
  • Support Materials on the official CBSE Board website.

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 they are facing. For example, if a business is finding it difficult to generate invoices for filing GST claims, students can do a project that takes raw data (list of transactions), transacts by category, GST tax Accounts for rates, and generates invoices in the proper format. Students can be extremely creative here.

They can use a variety of Python libraries to create user-friendly applications such as games, software for their school, software for fellow students with disabilities, and mobile applications, of course, to perform some of these projects. For this, some additional learning is required. , It should be encouraged. Students should know how to teach themselves.

Students should be sensitized to avoid plagiarism and copyright issues infringement while working on projects. For this teachers should take the necessary steps.
