The object_hook is an optional function that will be called with the result of any object literal decoded (a dict). With the CData Python Connector for JSON and the petl framework, you can build JSON-connected applications and pipelines for extracting, transforming, and loading JSON services. Generate data from a JSON file. The JSON is a light-weight data format due to which we save space by converting a python class object into a JSON string object (python class objects consume more space than the JSON object). Files for python-jsonpath-object-transform, version 0.1; Filename, size File type Python version Upload date Hashes; Filename, size python-jsonpath-object-transform-.1.tar.gz (2.9 kB) File type Source Python version None Upload date Mar 21, 2018 Example 4: Writing JSON to a file Sophisticated query expressions with minimal syntax.
