These types allow the storage and manipulation of various kinds of data: Numeric Types: ⮚int: Represents integers (e.g., 5, -10). ⮚float: Represents floating-point numbers (e.g., 3.14, -0.001). ⮚complex: Represents complex numbers (e.g., 3+4j). Sequence Types: ⮚str: Represents a sequence of characters (strings) (e.g., 'hello’). ⮚list: An ordered, mutable sequence of items (e.g., [1, 2, 3]). ⮚tuple: An ordered, immutable sequence of items (e.g., (1, 2, 3)) Standard Types in Python Mapping Type: ⮚dict: Stores key-value pairs, like a hash map or associative array (e.g., {'name': 'Alice', 'age': 25}). Set Types: ⮚set: An unordered collection of unique items (e.g., {1, 2, 3}). ⮚Frozen set: An immutable version of a set. Boolean Type: ⮚bool: Represents True or False. Python Basic Flow Control Flow control in Python allows you to dictate how your program executes based on conditions and loops. Here are the key components: 1. Conditional Statements (if, elif, else) Used to execute code blocks based on specific conditions. if condition: # Block of code if condition is True elif another_condition: # Block of code if another_condition is True else: # Block of code if none of the above conditions are True Flow Control-Conditional Statements (if, elif, else) Eg- x = 10 if x > 10: print("Greater than 10") elif x == 10: print("Equal to 10") else: print("Less than 10") Flow Control-Loops a. For Loop Used to iterate over sequences like lists, tuples, strings, etc. fruits = ["apple", "banana", "cherry"] for fruit in fruits: print(fruit) b. While Loop Executes a block of code as long as a condition is True. i=1 while i
