Declaring Variables in Python In Python, variables are used to store data. You can declare a variable by following these rules: Naming Variables: Variable names must begin with a letter or an underscore. Subsequent characters can be letters, digits, or underscores. Variable names are case-sensitive, which means "myVar" and "myvar" are different. Assigning Values: You can assign a value to a variable using the "=" operator. For example: my_var = 42 Data Types: Python is dynamically typed, meaning you don't need to declare the data type explicitly. The data type of a variable is determined automatically based on the assigned value. Assigning Variables in Python After declaring a variable, you can assign a value to it in several ways: Direct Assignment: As shown earlier, you can assign a value directly using the "=" operator. Multiple Assignments: Python allows you to assign values to multiple variables in a single line. For example: x, y, z = 10, 20, 30 Chained Assignments: You can assign the same value to multiple variables in a single line. For example: a = b = c = 42 Updating Variables: You can update the value of a variable by reassigning it. For example: counter = 0 and later counter = counter + 1 Swapping Variables: Python allows you to swap the values of two variables without using a temporary variable. For example: a, b = b, a Constants: While Python doesn't have constants in the traditional sense, it's a common convention to use uppercase variable names for constants.
