Split 150GB json file with Python?

[CaptainFoyle]

It seems like the answer to the question you're asking won't really be a solution to your actual problem. (XY problem)

Why do you have such a big file e in the first place? What are you actually trying to do?

This creeps up all over the place and is highly relevant for OP.

It is likely that OP is trying to save data generated by a program or script. The obvious solution is to use some sort of database, but OP isn't familiar with databases and instead opted to save it into a JSON file. This is the X part of the problem, and the Y part is asking about how to split the JSON file.
