How Can I Easily Inspect All Properties and Values of a Python Object for Debugging?

Exploring an Object's Properties: Uncovering Its State for Debugging

To effectively debug your scripts, knowing the current state of an object is essential. However, the built-in functions in Python do not provide an immediate solution to print all the current properties and values of an object.

Answering the Need

Fear not, for a combination of two functions can address your need. The vars() function returns a dictionary containing all the properties and values of the object, including properties that your code can't access directly.

To visualize this information effectively for debugging, the pprint() function from the pprint module comes into play. This function formats the dictionary into a readable and organized presentation.

Implementation

To achieve your desired functionality, simply employ the following steps:

1. Import the pprint module.
2. Use vars() to retrieve a dictionary of the object's properties.
3. Pass this dictionary as the argument to pprint() to generate a formatted output.

Example

Consider the following object:

my_object = {"name": "John Doe", "age": 30}

To debug and inspect the object's state, you can use the following code:

from pprint import pprint
pprint(vars(my_object))

This will produce the following output:

{'age': 30, 'name': 'John Doe'}

This format provides a clear representation of the object's properties and their corresponding values, easing your debugging efforts.
