Python, a versatile and high-level programming language, supports a rich set of data types that allow developers to work with different kinds of data efficiently. Understanding these data types is essential for effective Python programming and data manipulation. This guide provides an overview of Python’s built-in data types and their uses.
Description: Whole numbers without a fractional part. They can be positive or negative.
Example:
Operations: Python supports various arithmetic operations with integers, including addition, subtraction, multiplication, and division.
Description: Floating-point numbers represent real numbers with a decimal point.
Example:
Operations: Floats support operations like arithmetic, comparison, and rounding.
Description: Strings are sequences of characters enclosed in single quotes, double quotes, or triple quotes for multi-line strings.
Example:
Operations: Strings support operations like concatenation, slicing, and formatting.
Description: Booleans represent truth values and have two possible values: True and False.
Example:
Operations: Booleans are often used in conditional statements and logical operations.
Description: Lists are ordered, mutable collections of items that can be of different types. They are defined using square brackets.
Example:
Operations: Lists support various operations, including indexing, slicing, appending, and removing elements.
Description: Tuples are ordered, immutable collections of items. They are defined using parentheses.
Example:
Operations: Tuples support indexing and slicing but do not support item modification.
Description: Dictionaries are unordered, mutable collections of key-value pairs. They are defined using curly braces.
Example:
Operations: Dictionaries support operations like adding, removing, and updating key-value pairs.
Description: Sets are unordered collections of unique items. They are defined using curly braces or the set() function.
Example:
Operations: Sets support operations such as union, intersection, and difference.
Description: Complex numbers have a real part and an imaginary part. They are defined using j to represent the imaginary part.
Example:
Operations: Complex numbers support arithmetic operations like addition, subtraction, multiplication, and division.
Python allows conversion between different data types using built-in functions:
Convert to Integer: int()
Convert to Float: float()
Convert to String: str()
Convert to List: list()
Convert to Tuple: tuple()
Convert to Set: set()
Example:
Python supports a wide range of data types, each suited to different types of data and operations. From fundamental types like integers and floats to complex types like lists and dictionaries, understanding these data types is crucial for effective Python programming. By leveraging these types, developers can handle various data manipulation tasks efficiently and write robust code.
