Types of software libraries:
- Standard libraries. Most programming languages come with a standard library, which provides basic functions and classes that are considered essential for that language. For example, Python has a standard library that includes modules for file handling, regular expressions, and math operations.
- Third-party libraries. Many programming languages also have a vast ecosystem of third-party libraries to address a wide range of needs such as specialized functionalities, web frameworks, and GUIs.
- Personal libraries. Some developers create personal libraries to reuse code across projects. For example, they may create a library to address a specific need, standardize operations within their team, or to share it with others.
- Platform-specific libraries. These are libraries that were designed specifically for a certain platform. For example, they might tap into unique features of those platforms, offering functionalities that are not available elsewhere.
- Cross-language libraries. Some of the most popular libraries have versions in multiple languages. For example, the SQLite database library has interfaces available in various programming languages.
