Python, the versatile and widely-used programming language, boasts an extensive ecosystem of packages and libraries that cater to various programming needs. One peculiar aspect that often piques the curiosity of developers, especially those new to the language, is the relatively small size of many Python packages. This observation prompts the question: why are Python packages so small?
To unravel this mystery, it’s essential to understand the underlying mechanisms of Python package distribution and the nature of the language itself. Python is an interpreted language, meaning that code is executed line by line by the Python interpreter rather than being compiled into machine code. This characteristic allows Python packages to be distributed as source code, which is inherently more compact than compiled code.
Moreover, Python packages typically encapsulate the core functionality of a library or tool, excluding non-essential components like documentation and test suites from the distributed package. These additional files, though crucial for development and understanding how to use the package, are often made available separately or through version control systems, keeping the downloadable package size minimal.
The Python Package Index (PyPI), the official repository for third-party Python packages, plays a pivotal role in maintaining this compactness. Packages uploaded to PyPI are required to adhere to specific formatting standards, which encourage minimalism and efficiency in packaging. This ensures that only the necessary files for the package’s operation are included, further contributing to their small size.
Another contributing factor is the extensive use of dependencies in Python. Many packages rely on other packages for their functionality, allowing developers to avoid duplicating code. Instead, they can specify the required dependencies in their package metadata, ensuring that users install these dependencies alongside the main package. This approach not only reduces the size of individual packages but also promotes code reuse and modularity.
Lastly, the rise of minimalism and micro-libraries in the Python community has led to a trend of creating small, focused packages that do one thing well. This philosophy encourages developers to break down larger libraries into smaller, more manageable components, resulting in a proliferation of tiny, specialized packages.
