Introduce Python import sorting to our sanity test suite (#26768) 
* Add isort_code.sh to sanity tests

* Run tools/distrib/isort_code.sh

* Fine tune the import order for relative imports

* Make pylint and project generation happy

* Fix a few corner cases

* Use --check instead of --diff

* The import order impacts test result somehow

* Make isort print diff and check output at the same time

* Let tools/run_tests/python_utils be firstparty library

* Run isort against latest HEAD

Data transmission demo for using gRPC in Python

Four ways of data transmission when gRPC is used in Python. Official Guide

  • unary-unary

    In a single call, the client can only send request once, and the server can only respond once.

    client.py: simple_method

    server.py: SimpleMethod

  • stream-unary

    In a single call, the client can transfer data to the server an arbitrary number of times, but the server can only return a response once.

    client.py: client_streaming_method

    server.py: ClientStreamingMethod

  • unary-stream

    In a single call, the client can only transmit data to the server at one time, but the server can return the response many times.

    client.py: server_streaming_method

    server.py: ServerStreamingMethod

  • stream-stream

    In a single call, both client and server can send and receive data to each other multiple times.

    client.py: bidirectional_streaming_method

    server.py: BidirectionalStreamingMethod
