I have some difficulties generating a nested JSON using for loop in python. For generating a nested JSON, I got the length of dictionary on runtime and based on the dictionary length I want to generate nested JSON. eg. Read JSON with Python. Here we import the package json in line-1. From line-4 to line-29, we create an JSON object. This JSON object is then converted into a string by enclosing it within quotes and is assigned to the variable input.We use a for loop to loop through the array Address. I had been in a trouble for dynamically/recursively parsing and updating json. It took much time more than I expected. In the end, It turned out what made me confused was the difference in the concept of "scope" between python 2.7 and Java/C. I was writing code in python 2.7 but thinking in Java/C way.

If you are sure that there are no duplicate names, an even more effective (and pythonic way to do it is to use list comprehensions: List comprehensions is always faster than a for loop in Python. You can find a more detailed list of data types supported here. The built- in json package has the magic code that transforms your Python dict object in to the serialized JSON string.
