Basic Syntax and Data Types in Python 1. Variables Variables in Python are used to store data that can be referenced and manipulated later in the program. Python is dynamically typed, meaning you don't need to declare the type of a variable when you create one. You just assign a value to a variable using the assignment operator (=). python code # Variable assignment x = 10 name = "Alice" pi = 3.14 2. Strings Strings are sequences of characters enclosed in single quotes (') or double quotes ("). Python provides several operations and methods for working with strings. python code # Creating strings greeting = "Hello, World!" another_greeting = 'Hello, Python!' # String operations length = len(greeting) # Get length of the string upper_case = greeting.upper() # Convert to uppercase split_string = greeting.split(",") # Split the string into a list 3. Numbers Python supports integers and floating-point numbers. Integers are whole num...
