#Ensure you have pip version 9.0.1 or higher:python -m pip install --upgrade pip#If you cannot upgrade pip due to a system-owned installation, #you can run the example in a virtualenv:python -m pip install virtualenvvirtualenv venvsource venv/bin/activatepython -m pip install --upgrade pip#Install gRPC:python -m pip install grpcio#Install gRPC toolspython -m pip install grpcio-tools#Download the example# Clone the repository to get the example code:git clone -b v1.7.x https://github.com/grpc/grpc# Navigate to the "hello, world" Python example:cd grpc/examples/python/helloworld#Run a gRPC application#From the examples/python/helloworld directory:#1.Run the serverpython greeter_server.py#2.In another terminal, run the clientpython greeter_client.py#Congratulations! You’ve just run a client-server application with gRPC.

Update a gRPC service

#Edit examples/protos/helloworld.proto// The greeting service definition.service Greeter {  // Sends a greeting  rpc SayHello (HelloRequest) returns (HelloReply) {}  // Sends another greeting  rpc SayHelloAgain (HelloRequest) returns (HelloReply) {}}// The request message containing the user's name.message HelloRequest {  string name = 1;}// The response message containing the greetingsmessage HelloReply {  string message = 1;}#Generate gRPC code#From the examples/python/helloworld directory, run:python -m grpc_tools.protoc -I../../protos --python_out=. --grpc_python_out=. ../../protos/helloworld.proto#This regenerates helloworld_pb2.py which contains our generated request #and response classes and helloworld_pb2_grpc.py #which contains our generated client and server classes.#Update and run the application#Update the server#In the same directory, open greeter_server.pyclass Greeter(helloworld_pb2_grpc.GreeterServicer):  def SayHello(self, request, context):    return helloworld_pb2.HelloReply(message='Hello, %s!' % request.name)  def SayHelloAgain(self, request, context):    return helloworld_pb2.HelloReply(message='Hello again, %s!' % request.name)...#Update the client#In the same directory, open greeter_client.py.
