# Delete a List of Feature Flags and Flag Definitions

### Overview <a href="#overview" id="overview"></a>

Use this script to delete a list of feature flags and flag definitions from all projects.

#### Prerequisites <a href="#prerequisites" id="prerequisites"></a>

* Install the [Python Admin API Wrapper](/feature-management-experimentation/management-and-administration/api-best-practices/wrappers/python-admin-api.md).
* You've created an Admin API key from the Split UI.
* Make sure you have the workspace and environment names where your flags are defined.

### Configuration <a href="#configuration" id="configuration"></a>

Before running the script, update the following variables in the code:

* `ADMIN API KEY`: Your Split Admin API key.
* `feature_flags`: Update this array with the name of the feature flags you want to delete.

Run this script using Python 3 from your local machine or preferred development environment.

```python
from splitapiclient.main import get_client

#############################################
feature_flags = ['feature_flag1', 'feature_flag2', 'feature_flag3']
#############################################

client = get_client({'apikey': 'ADMIN API KEY'})

for project in client.workspaces.list():
    print("Project: "+project.name)
    for env in client.environments.list(project.id):
        print("Environment: "+env.name)
        for flagDef in client.split_definitions.list(env.id, project.id):
            for flag in feature_flags:
                if flagDef._name==flag:
                    print("Feature flag: "+flagDef.name+", deleting definition") 
                    client.splits.remove_from_environment(flag, env.id, project.id)
    for flag in feature_flags:
        for ff in client.splits.list(project.id):
            if flag==ff._name:
                print("deleting feature flag "+flag)
                project.delete_split(flag)
```
