Intelligence (AI), Machine Learning (ML), Internet of Things (IoT)

Unit II: Computational Thinking and Programming – 1

● Introduction to problem solving: Steps for problem solving (analysing the problem, developing an algorithm, coding, testing and debugging). representation of algorithms using flow chart and pseudo code, decomposition

● Familiarization  with  the  basics  of  Python  programming:  Introduction  to  Python,  features  of Python, executing a simple "hello world" program, execution modes: interactive mode and script mode, Python character set, Python tokens (keyword, identifier, literal, operator, punctuator), variables, concept of l-value and r-value, use of comments

● Knowledge of data types: number (integer, floating point, complex), boolean, sequence (string, list, tuple), none, mapping (dictionary), mutable and immutable data types

● Operators: arithmetic operators, relational operators, logical operators, assignment operator, augmented assignment operators, identity operators (is, is not), membership operators (in, not in)

● Expressions, statement, type conversion & input/output: precedence of operators, expression,

evaluation of expression, python statement, type conversion (explicit & implicit conversion), accepting data as input from the console and displaying output

● Errors: syntax errors, logical errors, runtime errors

● Flow of control: introduction, use of indentation, sequential flow, conditional and iterative flow control

●Conditional statements: if, if-else, if-elif-else, flowcharts, simple programs:  e.g.: absolute value, sort 3 numbers and divisibility of a number

● Iterative  statements:  for  loop,  range  function,  while  loop,  flowcharts,  break  and  continue statements, nested loops, suggested programs: generating pattern, summation of series, finding the factorial of a positive number etc

● Strings:  introduction,  indexing,  string  operations  (concatenation,  repetition,  membership  & slicing), traversing a string using loops, built-in functions: len(), capitalize(), title(), lower(), upper(), count(), find(), index(), endswith(), startswith(), isalnum(), isalpha(), isdigit(), islower(), isupper(), isspace(), lstrip(), rstrip(), strip(), replace(), join(), partition(), split()

● Lists: introduction, indexing, list operations (concatenation, repetition, membership & slicing),

traversing a list using loops, built-in functions: len(), list(), append(), extend(), insert(), count(), index(), remove(), pop(), reverse(), sort(), sorted(), min(), max(), sum(); nested lists, suggested programs: finding the maximum, minimum, mean of numeric values stored in a list; linear search on list of numbers and counting the frequency of elements in a list

● Tuples: introduction, indexing, tuple operations (concatenation, repetition, membership & slicing), built-in functions: len(), tuple(), count(), index(), sorted(), min(), max(), sum(); tuple assignment, nested tuple, suggested programs: finding the minimum, maximum, mean of values stored in a tuple; linear search on a tuple of numbers, counting the frequency of elements in a tuple

● Dictionary: introduction, accessing items in a dictionary using keys, mutability of dictionary (adding a new item, modifying an existing item), traversing a dictionary, built-in functions: len(), dict(), keys(), values(), items(), get(), update(), del(), clear(), fromkeys(), copy(), pop(), popitem(), setdefault(), max(), min(), count(), sorted(), copy(); suggested programs : count the number of times a character appears in a given string using a dictionary, create a dictionary with names of employees, their salary and access them

● Sorting techniques: Bubble and Insertion sort

● Introduction to Python modules: Importing module using 'import <module>' and using from statement, Importing math module (pi, e, sqrt, ceil, floor, pow, fabs, sin, cos, tan); random module (random, randint, randrange), statistics module (mean, median,mode)

Unit III: Society, Law and Ethics

● Data  protection:  Intellectual  Property  Right  (copyright,  patent,  trademark),  violation  of  IPR (plagiarism, copyright infringement, trademark infringement), open source softwares and licensing (Creative Commons, GPL and Apache)

● Cyber-crime:  definition,  hacking,  eavesdropping,  phishing  and  fraud  emails,  ransomware, preventing cyber crime

● Cyber  safety:  safely  browsing  the  web,  identity  protection,  confidentiality,  cyber  trolls  and bullying.
