# client.py
# Python client for connecting to the Code Debug Environment.
# Use this in training loops / evaluation scripts.
#
# Usage (sync):
#   with CodeDebugEnv(base_url="https://your-space.hf.space").sync() as env:
#       result = env.reset(difficulty="easy")
#       result = env.step(DebugAction(fixed_code="..."))
#
# Usage (async):
#   async with CodeDebugEnv(base_url="https://your-space.hf.space") as env:
#       result = await env.reset(difficulty="medium")
#       result = await env.step(DebugAction(fixed_code="..."))
