It has a vast ecosystem that includes tools for automation, data analysis, web development, and artificial intelligence/machine learning. It offers an easy-to-learn syntax, making it ideal for beginners to start their programming journey. Installing Python & Code Editors To start using Python, first install the latest stable version of Python from the official website ( Basic Input & Output Python allows users to accept user input and provide output with ease. Two common built-in functions are input() and print(). input() lets users enter text through the keyboard, while print() displays output on the screen. Example: name = input("Enter your name: ") print("Hello, " + name) String Object Functionality in Python Strings offer a rich set of features in Python. String Methods and Objects in Python Python has built-in methods for handling strings efficiently. Some examples include: upper(): Converts all string characters to uppercase lower(): Converts all string characters to lowercase strip(): Removes leading and trailing whitespace find(): Finds an index of a substring replace(): Replaces parts of a string with new text Example: text = "HellO World!" print(()) # OUTPUT: HELLO WORLD! print(()) # OUTPUT: hello world! print(()) # OUTPUT: HellO World List Object Methods and Operations Lists are mutable sequences of elements. Python provides various methods for changing lists, accessing elements, and modifying lists. Lists as Objects and their Methods append(): Adds an element to the end of the list insert(): Adds an element at the specified position remove(): Removes the first instance of a specified element pop(): Removes and returns the element at the specified position sort(): Sorts the list in ascending order reverse(): Reverses the elements in the list Example: numbers = [1, 5, 3, 4, 2] () # [1, 2, 3, 4, 5] se() # [5, 4, 3, 2, 1] Inserting and Removing Items in Lists +: Concatenates lists *: Repeats a list del: Deletes elements or slices [:]: Creates a shallow copy of a list
