Tuples in Python Tuples are immutable sequences of Python objects. They are similar to lists but cannot be changed once created. Creating Tuples Tuples are created by enclosing a comma-separated sequence of values within parentheses. Python Accessing Tuple Elements Tuples can be accessed using indexing, similar to lists. Python Tuple Operations While tuples are immutable, … Read more
List comprehensions provide a concise way to create lists in Python. They are often more readable and efficient than traditional for loops for creating lists. Syntax: Python Example: Python Key Points Read More..
List Methods and Functions Python provides a rich set of methods and functions to manipulate lists. List Methods List methods are functions that are specific to list objects and modify the list in place. List Functions List functions are built-in functions that can be used with lists. Example Python Read More..
Creating Lists A Python list is created by enclosing a comma-separated sequence of items within square brackets []. Lists can contain elements of different data types. Python Accessing List Elements You can access individual elements in a list using their index. Python uses zero-based indexing, meaning the first element has an index of 0. Python … Read more
Lists are versatile data structures in Python used to store collections of items. They are ordered, mutable, and can contain elements of different data types. Creating Lists Python Accessing Elements Modifying Lists Other List Operations Example: Python Read More..
Data structures are fundamental to computer science. They are ways to organize and store data for efficient access and modification. Choosing the right data structure can significantly impact the performance of an algorithm. Built-in Data Structures in Python Python provides several built-in data structures: Sequences Mapping Set Other Data Structures (Not Built-in) While Python provides … Read more
Loop control statements modify the normal flow of a loop. Python provides three keywords for this purpose: break, continue, and pass. break Python continue Python pass Python Key points: Read More..
Nested loops occur when one loop is placed inside another loop. This construct is useful for iterating over multiple sequences or performing repetitive tasks within a loop. Example: Nested For Loops Python This code will print all combinations of i and j where both range from 0 to 2. Key points: Example: Creating a Multiplication … Read more
A while loop in Python repeatedly executes a block of code as long as a given condition is true. It’s often used when the number of iterations is unknown beforehand. Syntax: Python Example: Python Key Points Common Use Cases Example: User Input Validation Python Read more..
Understanding the For Loop A for loop in Python is used to iterate over a sequence (like a list, tuple, string, or range) or other iterable objects. It’s a concise way to perform actions on each item in a collection. Basic Syntax: Python Iterating Over Sequences Python The range() Function The range() function generates a … Read more
