# Retry Example in gRPC Python
|
|
|
|
## Prerequisite
|
|
|
|
* grpcio >= 1.39.0
|
|
* grpcio-tools >= 1.39.0
|
|
|
|
## Running the example
|
|
|
|
In terminal 1, start the flaky server:
|
|
|
|
```sh
|
|
python3 flaky_server.py
|
|
```
|
|
|
|
In terminal 2, start the retry clients:
|
|
|
|
```sh
|
|
python3 retry_client.py
|
|
# Or
|
|
python3 async_retry_client.py
|
|
```
|
|
|
|
## Expect results
|
|
|
|
The client RPC will succeed, even with server injecting multiple errors. Here is an example server log:
|
|
|
|
```sh
|
|
$ python3 flaky_server.py
