CBSE Class 12 Computer Science Practical

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. 
  • 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. 
  • Remove all the lines that contain the character `a’ in a file and write it to another file. 
  • Write a random number generator that generates random numbers between 1 and 6 (simulates a dice). 
  • Write a Python program to implement a stack and queue using a list data-structure. 
  • Take a sample of ten phishing e-mails (or any text file) and find most commonly occurring word(s) 10 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 
  • Similar exercise may be framed for other cases.

  • Similar exercise may be framed for other cases. 
  • Integrate SQL with Python by importing the MySQL module. 

Project 

The aim of the class project is to create something that is tangible and useful using Python / Python and 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 sensitized to avoid plagiarism and violations of copyright issues while working on projects. Teachers should take necessary measures for this.
