PyJNIus is a simple-to-use Java interface for Python. However, JPype is a better alternative.
pip install Cython
pip install pyjnius
import os
os.environ["CLASSPATH"] = "/path/to/your.jar"
from jnius import autoclass
YourClass = autoclass(path.to.YourClass)
yourObj = YourClass()
Note: Avoid using the same …
JPype, py4j and PyJNIus are all good options for Java interface for Python. Jpype is easy to use and widely adopted. PyJNIus is an even easier solution compred to JPype. py4j is more complicated to use compared to JPype and PyJNIus, however, it has a better performance, generally speaking.
This article discusses different ways to write long strings in Python.
A long string can be put on the the same line, which is ugly of course.
The function eval takes a single line of code as string,
evaluates it,
and returns the value.
Notice that objects in the evaluated expression
must be present in the current scope,
otherwise,
exceptions will be thrown.
Even though eval (together with exec) might be useful in some situations,
e.g., when implementing a REPL.
It is strongly suggested that you avoid using eval
The GIL is controversial because it prevents multithreaded CPython programs from taking full advantage of multiprocessor systems in certain situations. Note that potentially blocking or long-running operations, such as I/O, image processing, and NumPy number crunching, happen outside the GIL. Therefore it is only in multithreaded programs that spend …
