CBSE Class 12 Computer Science Syllabus 2024 for Practical

Class 12 Computer Science Syllabus 2024 is updated with two sub-divisions including Python programming and Database Management. Read out the updated CBSE Class 12 Computer Science 2024 syllabus for practicals.

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 list.
• Create a CSV file by entering user-id and password, read and search the password for
  given user id.

Database Management

• Create a student table and insert data. Implement the following SQL commands on the
  student table:
  o ALTER table to add new attributes / modify data type / drop attribute
  o UPDATE table to modify data
  o ORDER By to display data in ascending / descending order
  o DELETE to remove tuple(s)
  o 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.
