12th CS Python Program list 2024-25

   As per CBSE Practical List 2024-25

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 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 generatesrandom numbers between 1 and 6 (simulatesa 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.
