Import Module vs. From Module Import: Which Python Import Method Should You Choose?

Import Module vs. From Module Import: A Comprehensive Guide

Importing modules is a fundamental aspect of Python programming. To enhance code readability and efficiency, it's essential to understand the differences between "import module" and "from module import."

Should You Use "import module" or "from module import"?

The choice largely depends on personal preference and coding style. However, there are pros and cons associated with each method:

"import module"

• Pros:

  • Minimal maintenance of import statements
  • No need to import additional items to use other module contents

• Cons:

  • Tedious and redundant typing of "module.foo"

"from module import foo"

• Pros:

  • Less typing required
  • Greater control over accessible module items

• Cons:

  • Import statements must be updated to use new module items
  • Loss of context regarding the source of imported functions

Avoid "from module import *":

While it may be tempting to import all module contents with "from module import *," this practice is strongly discouraged. It can lead to module dependency issues and difficulty in tracking the origin of used items within code.

Recommendations:

Overall, maintain consistency in your import style. If you prefer "import module," use it consistently throughout your codebase. Similarly, if you find "from module import" more convenient, adopt it as your default approach.

Remember, the critical factors are readability, maintainability, and avoiding common pitfalls like "from module import *." By considering these aspects, you can maximize the effectiveness of your Python code imports.
