Understanding Python's built-in data types: int, float, str, bool
Python has several built-in data types that form the foundation of all programs. Integers (int) represent whole numbers of unlimited size (limited only by available memory). Floating-point numbers (float) represent real numbers with decimal points and have precision limitations due to how they're stored in memory. Strings (str) represent sequences of Unicode characters and can be created using single, double, or triple quotes. Boolean (bool) represents truth values True and False, which are actually subclasses of integers (True == 1, False == 0). Python also has a complex number type for complex mathematics. Each data type has specific characteristics: integers are precise, floats are approximate, strings are immutable, and booleans are logical values. You can check the type of any object using the type() function. Understanding these basic data types is essential as they're used in virtually every Python program. Python's dynamic typing means variables can change types, but this flexibility requires careful programming to avoid type-related errors.
