To import the Java package com.typesafe.config.impl.SimpleConfig into Python using py4j, follow these steps:

  1. Start the py4j gateway server:
from py4j.java_gateway import JavaGateway
gateway = JavaGateway()
  1. Create a Java object for SimpleConfig:
simple_config = gateway.jvm.com.typesafe.config.impl.SimpleConfig()
  1. Use the Java object in Python code:
# set a configuration property
simple_config.setProperty("foo.bar", "123")

# get a configuration value
value = simple_config.getString("foo.bar")
print(value) # prints "123"

Note: If you need to use methods with complex parameters or return types, you may need to create and pass Java objects to/from Python. Consult the py4j documentation for details.
