trying to locate a working grpc to install

[snippsat]

Quick test,homepage
Doing it in virtual environment,it's now build into Python newer versions as you use 3.7.

E:\div_code
λ python -m venv grpv_env

E:\div_code
λ cd grpv_env\

E:\div_code\grpv_env
λ E:\div_code\grpv_env\Scripts\activate

# Install into environment
(grpv_env) E:\div_code\grpv_env
λ pip install grpcio
Collecting grpcio
  Downloading .....
Installing collected packages: six, grpcio
Successfully installed grpcio-1.20.1 six-1.12.0

(grpv_env) E:\div_code\grpv_env
λ pip install ptpython
Collecting ptpython ....
  Installing collected packages: parso, jedi, docopt, pygments, wcwidth, prompt-toolkit, ptpython
Successfully installed docopt-0.6.2 jedi-0.13.3 parso-0.4.0 prompt-toolkit-2.0.9 ptpython-2.0.4 pygments-2.4.0 wcwidth-0.1.7

I also install ptpython into environment,this make a lot easier to explore a package that not has so much Python documentation.

(grpv_env) E:\div_code\grpv_env
λ ptpython
>>> import grpc

>>> grpc.__version__
'1.20.1'

So there is a lot of method under grpc eg grpc.Call ect...
As i using ptpython all methods is showing up automatically after grpc.,with doc string.
There is a lot method if list all without special methods(__something__).

Output:
>>> [i for i in dir(grpc) if not i.startswith('__')]
['AuthMetadataContext', 'AuthMetadataPlugin', 'AuthMetadataPluginCallback', 'Call', 'CallCredentials', 'Channel', 'ChannelConnectivity', 'ChannelCredentials', 'ClientCallDetails', 'Future', 'FutureCancelledError', 'FutureTimeoutError', 'GenericRpcHandler', 'HandlerCallDetails', 'RpcContext', 'RpcError', 'RpcMethodHandler', 'Server', 'ServerCertificateConfiguration', 'ServerCredentials', 'ServerInterceptor', 'ServiceRpcHandler', 'ServicerContext', 'Status', 'StatusCode', 'StreamStreamClientInterceptor', 'StreamStreamMultiCallable', 'StreamUnaryClientInterceptor', 'StreamUnaryMultiCallable', 'UnaryStreamClientInterceptor', 'UnaryStreamMultiCallable', 'UnaryUnaryClientInterceptor', 'UnaryUnaryMultiCallable', '_create_servicer_context', '_cygrpc', '_cython', '_grpcio_metadata', 'abc', 'access_token_call_credentials', 'channel_ready_future', 'composite_call_credentials', 'composite_channel_credentials', 'contextlib', 'dynamic_ssl_server_credentials', 'enum', 'insecure_channel', 'intercept_channel', 'logging', 'metadata_call_credentials', 'method_handlers_generic_handler', 'secure_channel', 'server', 'six', 'ssl_channel_credentials', 'ssl_server_certificate_configuration', 'ssl_server_credentials', 'stream_stream_rpc_method_handler', 'stream_unary_rpc_method_handler', 'sys', 'unary_stream_rpc_method_handler', 'unary_unary_rpc_method_handler']

Version pip show:

(grpv_env) E:\div_code\grpv_env
λ pip show grpcio

Looking at doc there is also pip install grpcio-tools
With a hello world example after clone from Repo.
So can do a test of that:

(grpv_env) E:\div_code\grpv_env
λ pip install grpcio-tools
Collecting grpcio-tools
  Downloading .....      
Installing collected packages: protobuf, grpcio-tools
Successfully installed grpcio-tools-1.20.1 protobuf-3.7.1

(grpv_env) E:\div_code\grpv_env
λ git clone -b v1.20.0 https://github.com/grpc/grpc
Cloning into 'grpc'...

Test server --> client.

(grpv_env) E:\div_code\grpv_env\grpc\examples\python\helloworld ((no branch))
λ python greeter_server.py

Now in a other cmder window.

(grpv_env) E:\div_code\grpv_env\grpc\examples\python\helloworld ((no branch))
λ python greeter_client.py
Greeter client received: Hello, you!
