Object to dictionary conversion

Object to dictionary conversion is a serialization process frequently required when working with data formats like [[JSON]] in programming languages such as Python^[400-devops-09-scripting-language-python-introduction-part-3json-readme.md].

Necessity

This conversion becomes necessary when standard serialization libraries encounter complex types. For instance, the Python json.dumps() function is designed to handle "full dictionaries," meaning it cannot directly serialize custom class instances or objects^[400-devops-09-scripting-language-python-introduction-part-3json-readme.md]. Attempting to pass a dictionary containing objects to a JSON serializer typically results in a TypeError, explicitly stating that the object is not JSON serializable^[400-devops-09-scripting-language-python-introduction-part-3json-readme.md].

Implementation in Python

In Python, this conversion is commonly achieved by accessing the __dict__ attribute of an object^[400-devops-09-scripting-language-python-introduction-part-3json-readme.md]. This attribute contains the object's internal namespace, effectively representing the object's properties as a standard dictionary. By transforming object values into dictionary values, the data structure becomes compatible with serialization functions^[400-devops-09-scripting-language-python-introduction-part-3json-readme.md].

Example Workflow

A typical workflow involves iterating through a collection of objects and constructing a new dictionary where the values are the dictionary representations of the original objects^[400-devops-09-scripting-language-python-introduction-part-3json-readme.md].

# Example: Converting a dictionary of Customer objects to a dictionary of dictionaries
customerDict = {}
for id in customers:
    customerDict[id] = customers[id].__dict__

Once converted, the data is ready for transport or storage^[400-devops-09-scripting-language-python-introduction-part-3json-readme.md].
