+## Data transmission demo for using gRPC in Python
+
+在Python中使用gRPC时, 进行数据传输的四种方式。
+
+- #### 简单模式 
+
+  没啥好说的,跟调普通方法没差
+
+  `client.py - line:13 - simple_method`
+
+  `server.py - line:17 - SimpleMethod`
+
+- #### 客户端流模式
+
+  在一次调用中, 客户端可以多次向服务器传输数据, 但是服务器只能返回一次响应.
+
+  `clien.py - line:24 - client_streaming_method `
+
+  `server.py - line:25 - ClientStreamingMethod`
+
+- #### 服务端流模式 
+
+  在一次调用中, 客户端只能一次向服务器传输数据, 但是服务器可以多次返回响应
+
+  `clien.py - line:42 - server_streaming_method`
+
+  `server.py - line:35 - ServerStreamingMethod`
+
+- #### 双向流模式
+
+  在一次调用中, 客户端和服务器都可以向对方多次收发数据
+
+  `client.py - line:55 - bidirectional_streaming_method`
+
+  `server.py - line:51 - BidirectionalStreamingMethod`

+##  Data transmission demo for using gRPC in Python
+
+Four ways of data transmission when gRPC is used in Python.
+
+- #### unary-unary
+
+  There's nothing to say. It's no different from the usual way.
+
+  `client.py - line:13 - simple_method`
+
+  `server.py - line:17 - 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.
+
+  `clien.py - line:24 - client_streaming_method`
+
+  `server.py - line:25 - 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.
+
+  `clien.py - line:42 - server_streaming_method`
+
+  `server.py - line:35 - ServerStreamingMethod`
+
+- #### stream-stream
+
+  In a single call, both client and server can send and receive data 
+  to each other multiple times.
+
+  `client.py - line:55 - bidirectional_streaming_method`
