`import module` vs. `from module import`: Which Python Import Method Should You Choose?

Navigating the Labyrinth: 'import module' versus 'from module import'

As a budding Python developer, selecting the right approach for importing modules can lay the foundation for good coding practices. This question delves into the nuances of using 'import module' and 'from module import'.

'import module' - Neatness with Caveats

Importing an entire module with 'import module' offers the advantage of accessing all its contents. But this simplicity can turn into a drawback for larger modules, as typing 'module.foo' for each subcomponent becomes verbose. Additionally, this approach may not be suitable when only a few specific elements are needed.

'from module import foo' - Granularity at a Cost

'from module import foo' allows targeted import of specific module elements. This streamlines code and provides more control over the accessible functions and classes. However, it comes with its own challenges. Updating import statements becomes necessary as new elements are required, and the lack of module context can make understanding the significance of imported items more difficult (e.g., 'ceil()' vs. 'math.ceil()').

The Taboo: 'from module import *'

Indiscriminately importing all elements of a module using 'from module import *' can lead to unintended consequences. This practice makes it difficult to remove the imported module later. It can be challenging to trace dependencies and determine which elements are coming from the imported module, potentially leading to unforeseen errors and unexpected behavior.

Conclusion: A Balance of Needs

Ultimately, the choice between 'import module' and 'from module import' depends on the specific needs and preferences of the developer. While 'import module' offers the convenience of comprehensive import, 'from module import' provides greater control and flexibility. Avoiding the use of 'from module import *' is crucial for maintainability and code clarity.
