Preamble: The objective of the course is to equip the learners to develop multi-module software solutions for real world computational problems using Python. It encompasses the Python programming environment, syntax, data representations, intermediate level features, GUI programming, Object Oriented Programming and data processing. This course lays the foundation to develop modular software solutions including complex interactive applications, network applications, and data-driven intelligent applications.

Prerequisite: Basic knowledge in Computational Problem Solving, A course in any programming language.

Course Outcomes: After the completion of the course the student will be able to

CO2: Illustrate uses of conditional (if, if-else and if-elif-else ) and iterative (while and for) statements in Python programs. (Cognitive Knowledge level: Apply)

CO3: Develop programs by utilizing the Python programming constructs such as Lists, Tuples, Sets and Dictionaries. (Cognitive Knowledge level: Apply)

CO4: Develop graphical user interface for solutions using Python libraries. (Cognitive Knowledge level: Apply)

CO5: Implement Object Oriented programs with exception handling. (Cognitive Knowledge level: Apply)

Continuous Internal Evaluation Pattern: 

Attendance : 10 marks 

Continuous Assessment Test : 25 marks 

Continuous Assessment Assignment : 15 marks 

Internal Examination Pattern: 

Each of the two internal examinations has to be conducted out of 50 marks. The first series test shall be preferably conducted after completing the first half of the syllabus and the second series test shall be preferably conducted after completing the remaining part of the syllabus. 

There will be two parts: Part A and Part B. Part A contains 5 questions (preferably, 2 questions each from the completed modules and 1 question from the partly completed module), having 3 marks for each question adding up to 15 marks for part A. 

Students should answer all questions from Part A. Part B contains 7 questions (preferably, 3 questions each from the completed modules and 1 question from the partly completed module), each with 7 marks. Out of the 7 questions, a student should answer any 5. 

End Semester Examination Pattern: There will be two parts; Part A and Part B. Part A contains 10 questions with 2 questions from each module, having 3 marks for each question. Students should answer all questions. Part B contains 2 questions from each module of which a student should answer any one. Each question can have a maximum of 2 sub-divisions and carries 14 marks.  

Sample Course Level Assessment Questions 

Course Outcome1(CO1): 

1. What is type conversion? How is it done in Python? 

2. Write a note on the Python editors. 

Course Outcome 2(CO2): 

1. Write a Python program which takes a positive integer n as input and finds the sum of cubes all positive even numbers less than or equal to the number. 

2. What is printed when the below code is executed? 

mysum = 0 

 for i in range(5, 11, 2): 

     mysum += i 

     if mysum == 5: 

             break 

   mysum += 1

 print(mysum) What would be the output if ‘break’ is replaced with ‘continue’ in the above code fragment? 

Course Outcome 3(CO3): 

1. Given is a list of of words, wordlist, and a string, name. Write a Python function which takes wordlist and name as input and returns a tuple. The first element of the output tuple is the number of words in the wordlist which have name as a substring in it. The second element of the tuple is a list showing the index at which the name occurs in each of the words of the wordlist and a 0 if it doesn’t occur. 

2. What is the value of L after you run the code below? L = ["life", "answer", 42, 0] 

for thing in L: 

     if thing == 0: 

         L[thing] = "universe" 

     elif thing == 42: 

         L[1] = "everything" 

Course Outcome 4(CO4): 

1. A bouncy program is defined as follows – The program computes and displays the total distance traveled by a ball, given three inputs—the initial height from which it is dropped, its bounciness index, and the number of bounces. Given the inputs write a GUI-based program to compute the total distance traveled. 

2. Write a Python program to find the quadrant of a point, say (x,y). 

Course Outcome 5(CO5): 

1. Write a Python program to implement the addition, subtraction, and multiplication of complex numbers using classes. Use constructors to create objects. The input to the program consist of real and imaginary parts of the complex numbers. 

2. Explain inheritance in Python using suitable examples. 

Course Outcome 6(CO6): 

1. Given a file “auto.csv” of automobile data with the fields index, company, body-style, wheelbase, length, engine-type, num-of-cylinders, horsepower, average-mileage, and price, write python code to 

1. Clean and Update the CSV file 

2. Print total cars of all companies 

3. Find the average mileage of all companies 

4. Find the highest priced car of all companies. 

2. Given two matrices A and B, write a program to find the product of A and B^T .
