A Clojure library providing deep bidirectional integration between the JVM and Python, allowing Clojure/Java code to call Python libraries and vice versa. It bridges JVM and Python objects with GC-linked lifetimes, efficient numpy data copies, and supports embedding a Clojure REPL inside a Python host process.

Use cases

• call python libraries from clojure
• use numpy and pandas from the jvm
• embed clojure in a python application
• use machine learning libraries like pytorch from clojure
• bridge jvm objects and python objects
• run a clojure repl inside python

When to choose

• you are on the JVM and need Python's ecosystem (numpy, ML libraries) without leaving Clojure/Java
• you want bidirectional interop with GC-safe object lifetimes
• you need a Java-only API to embed Python without writing Clojure

When to avoid

• you need a pure-Python or pure-Clojure solution without cross-language overhead
• your project requires strict GIL-free high-throughput calls to many small Python functions
• you are not on the JVM platform
