Enroll in our Courses Class XI Computer Science Python to gain hands-on experience.
4.8 out of 5 based on 30 reviews
Computer Science in Class XI introduces foundational concepts in programming using Python, a beginner-friendly, high-level language. It focuses on developing problem-solving skills through computational thinking and algorithm design. Students learn Python’s syntax, data types, control structures (if-else, loops), and functions, which help them write efficient and reusable code.
Introduction to computer system, hardware, software, input device, output device, CPU, memory (primary, cache and secondary), units of memory (Bit, Byte, KB, MB, GB, TB, PB)
System software (operating systems, system utilities, device drivers), programming tools and language translators (assembler, compiler & interpreter), application software
Functions of operating system, OS user interface
NOT, AND, OR, NAND, NOR, XOR, truth table, De Morgan’s laws and logic circuits
Binary, Octal, Decimal and Hexadecimal number system; conversion between number systems.
Encoding schemes
Representation of Algorithms using Flow Chart and pseudo code
Barebones of Python Programs, Python Character Set, Token (Keywords, Literals, Delimiters, operators), Variables
Number (integer, floating point, complex), boolean, sequence (string, list, tuple), none, mapping (dictionary), mutable and immutable data types
Arithmetic operators, relational operators, logical operators, assignment operator, augmented assignment operators, identity operators (is, is not), membership operators (in, not in)
Precedence of operators, expression, evaluation of expression, python statement, type conversion (explicit & implicit conversion), accepting data as input from the console and displaying output
Syntax errors, logical errors, runtime errors
Introduction, use of indentation, sequential flow, conditional and iterative flow control
if, if-else, if-elif-else, flowcharts, simple programs: e.g.: absolute value, sort 3 numbers and divisibility of a number
For Loop, range function, While Loop, flowcharts, Break and Continue statements, Nested Loops (Programming using Loops)
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(), etc.
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, (Programming with lists)
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
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
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)
