How can I read large JSON files in Python efficiently?

You can use the json module along with streaming techniques to read large JSON files without loading them entirely into memory.

What are some libraries that can help with this?

Libraries like pandas and ijson are great for handling large JSON files. ijson allows for iterative parsing.

Can you show me a code example using ijson?

Sure! Here's a simple example:

import ijson

with open('large_file.json', 'r') as f:
    for item in ijson.items(f, 'item'):  # Adjust 'item' based on your JSON structure
        print(item)

What if my JSON file is nested?

You can still use ijson by specifying the correct prefix in the ijson.items() function to navigate through the nested structure.
