# Use python in the devops-toolkit | ||
|
||
To use the existing container isntead of creating one, use `docker exec` command instead of `docker run` | ||
|
||
```bash | ||
docker exec -it my_devops_toolkit /bin/bash | ||
``` | ||
|
||
## Use case 1: Run python sample code provided in the container | ||
|
||
```bash | ||
docker run --rm --network host -it devops-toolkit:latest | ||
# You now in the container terminal | ||
python3 samples/python/rectangle_area_calculator.py | ||
``` | ||
|
||
## Use case 2: Clone external code to container | ||
|
||
```bash | ||
docker run --rm --network host -it devops-toolkit:latest | ||
# You now in the container terminal | ||
|
||
# Clone code | ||
mkdir python_workspace | ||
cd python_workspace | ||
git clone https://github.com/geekcomputers/Python.git | ||
|
||
# Now run your cloned script | ||
cd Python | ||
python3 Day_of_week.py | ||
``` | ||
|
||
## Use case 3: Mount external code to container | ||
|
||
Clone the code to the host then mount to container | ||
|
||
```bash | ||
# Clone code on the host | ||
docker run --rm -v "$(pwd)":/root/python_workspace --network host -it devops-toolkit:latest | ||
# Run the python code as usual | ||
``` | ||
