MST-024: DATA ANALYSIS WITH PYTHON

Course Code: MST-024

Assignment Code: MST-024/TMA/2025

Maximum Marks: 50

Note: All questions are compulsory. Answer in your own words.

1(a). Differentiate between lists and tuples in Python.

(b). Write a Python program that demonstrates:

(i) A list of integers with operations like adding, removing, and modifying elements.

(ii) A tuple of integers and explain why tuples are immutable.

2. Write a Python program that takes an integer input from the user:

(i) Check if the number is positive, negative, or zero using an if...elif...else statement.

(ii) Print a suitable message based on the result.

3. The following datas consist of sales of a product for 6 months:

Month	Sales (in Rs`)
Jan	22000
Feb	25000
Mar	30000
Apr	28000
May	35000
Jun	37000

Write a Python program to

(i) create a list named SD for the given sales data.

(ii) Use a suitable loop function to compute the average sales. Verify it with the built in function.

(iii) Extract the months having sales greater than ` 30,000.

(iv) Plot a line chart using Matplotlib to show given monthly sales of the product. Also, add appropriate labels, title, and legend

4. Write a Python program using NumPy to

(i) Create following two matrices A and B with following elements.

(ii) Compute the (a) Addition, (b) Multiplication and (c) Inverse of these matrices.

(iii) Combine the given matrices colume-wise.

arr = np.array[4, 5, 6]

print(arr)

(c) Write a Python program to accept a list of tuples (product_name, price) for 5 items from the user, then sort the list by price in descending order using a function.

2(a). Describe the key features of Spyder.

(b) Explain how file handling works in Python for text files. Mention different file modes, and a short description of read(), readline() and write().
