# Python client for micro_traffic_sim gRPC Server
[](https://www.python.org/downloads/)
[](https://peps.python.org/pep-0561/)
Python client library for the microscopic traffic simulation gRPC server with full type hints support.
## Installation
```bash
pip install micro-traffic-sim
```
## Usage
```python
import grpc
from micro_traffic_sim import (
ServiceStub,
SessionReq,
Cell,
Point,
ZoneType,
)
# Connect to server
channel = grpc.insecure_channel("127.0.0.1:50051")
client = ServiceStub(channel)
# Create a new session
response = client.NewSession(SessionReq(srid=0))
session_id = response.id.value
# Push grid cells, trips, traffic lights, and run simulation...
```
## Documentation
- **Full example**: See [examples/](https://github.com/LdDl/micro_traffic_sim_grpc/tree/master/clients/python/examples) for a complete simulation workflow
## Running the example
1. Start the gRPC server:
```bash
cargo run --features server --bin micro_traffic_sim
```
2. Run the example (from repository root):
```bash
source clients/python/.venv/bin/activate
python clients/python/examples/main.py
```
3. Generate visualization:
```bash
python clients/python/examples/main.py > clients/python/examples/output.txt
gnuplot clients/python/examples/plot_anim.gnuplot
```
