Understanding the Error

Let's break down the error:

Package Confusion: The message 'pprint' is not a package further clarifies that Python considers pprint to be a module rather than a package containing submodules.

The Solution: Correcting Your Import Statement

The good news is that this error can be easily fixed. The pprint module is indeed a single module containing a function named pprint, but it does not have a submodule structure. Therefore, to correctly import the pprint function, we should change our import statement to the following:

Explanation of the Correct Import

from pprint: This specifies that we are importing from the pprint module.

import pprint: This indicates that we want to bring in the pprint function from that module.

as p: This renames the function pprint to p for convenience, allowing you to call it more succinctly in your code.

Example: Using the Correct Import

Here's an example of how you can use the corrected import statement effectively:

In this example, using pdata will pretty-print the data dictionary with a more readable output.

Conclusion

The ModuleNotFoundError is a common stumbling block for Python learners, particularly when it comes to correctly importing modules. Understanding how to import the pprint module properly is a key lesson in mastering Python's import system. By using the straightforward syntax shown above, you can prevent this error and take full advantage of the pprint functionality in your programming projects.

Remember, when in doubt, always check the documentation or explore the module structure to ensure you are importing correctly! Happy coding!
