What are the built-in types available In Python?

Câu trả lời

In Python, there are several built-in data types that are categorized into different classes. These data types are integral to the language and are used to define the type of a variable, which in turn determines what kind of operations can be performed on it. Here are the built-in data types available in Python:

  • Text Type:

    • str (String): Used to represent text data. It is a sequence of Unicode characters enclosed in single, double, or triple quotes.
  • Numeric Types:

    • int (Integer): Represents whole numbers, both positive and negative, without a fractional component.
    • float (Floating-point number): Represents real numbers and includes a decimal point. It can also represent numbers in scientific notation with an "e" to indicate the power of 10.
    • complex (Complex number): Represents a number with a real and an imaginary part, denoted as (real part) + (imaginary part)j.
  • Sequence Types:

    • list: An ordered and mutable collection of items that can be of different data types.
    • tuple: An ordered and immutable collection of items that can be of different data types.
    • range: Represents a sequence of numbers, typically used in for loops for iteration.
  • Mapping Type:

    • dict (Dictionary)...
