Type annotations for
[boto3.EMR 1.14.15](https://boto3.amazonaws.com/v1/documentation/api/1.14.15/reference/services/emr.html#EMR) service
compatible with [mypy](https://github.com/python/mypy), [VSCode](https://code.visualstudio.com/),
[PyCharm](https://www.jetbrains.com/pycharm/) and other tools.
Generated by [mypy-boto3-buider 2.2.0](https://github.com/vemel/mypy_boto3_builder).
More information can be found on [boto3-stubs](https://pypi.org/project/boto3-stubs/) page.
## How to install
Make sure you have [mypy](https://github.com/python/mypy) installed and activated in your IDE.
Install `boto3-stubs` for `EMR` service.
```bash
python -m pip install boto3-stubs[emr]
```
## How to use
### Client annotations
`EMRClient` provides annotations for `boto3.client("emr")`.
```python
import boto3
from mypy_boto3_emr import EMRClient
from mypy_boto3_emr.paginator import (
ListBootstrapActionsPaginator,
ListClustersPaginator,
ListInstanceFleetsPaginator,
ListInstanceGroupsPaginator,
ListInstancesPaginator,
ListSecurityConfigurationsPaginator,
ListStepsPaginator,
)
from mypy_boto3_emr.type_defs import ApplicationTypeDef, ...
from mypy_boto3_emr.waiter import ClusterRunningWaiter, ClusterTerminatedWaiter, StepCompleteWaiter
client: EMRClient = boto3.client("emr")
# now client usage is checked by mypy and IDE should provide code auto-complete
# works for session as well
session = boto3.session.Session(region="us-west-1")
session_client: EMRClient = session.client("emr")
```
### Paginators annotations
`mypy_boto3_emr.paginator` module contains type annotations for all paginators.
```python
client: EMRClient = boto3.client("emr")
# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
list_bootstrap_actions_paginator: ListBootstrapActionsPaginator = client.get_paginator("list_bootstrap_actions")
list_clusters_paginator: ListClustersPaginator = client.get_paginator("list_clusters")
list_instance_fleets_paginator: ListInstanceFleetsPaginator = client.get_paginator("list_instance_fleets")
list_instance_groups_paginator: ListInstanceGroupsPaginator = client.get_paginator("list_instance_groups")
list_instances_paginator: ListInstancesPaginator = client.get_paginator("list_instances")
list_security_configurations_paginator: ListSecurityConfigurationsPaginator = client.get_paginator("list_security_configurations")
list_steps_paginator: ListStepsPaginator = client.get_paginator("list_steps")
```
### Waiters annotations
`mypy_boto3_emr.waiter` module contains type annotations for all waiters.
```python
client: EMRClient = boto3.client("emr")
# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
cluster_running_waiter: ClusterRunningWaiter = client.get_waiter("cluster_running")
cluster_terminated_waiter: ClusterTerminatedWaiter = client.get_waiter("cluster_terminated")
step_complete_waiter: StepCompleteWaiter = client.get_waiter("step_complete")
```
### Typed dictionations
`mypy_boto3_emr.type_defs` module contains structures and shapes assembled
to typed dictionaries for additional type checking.
```python
def get_structure() -> ApplicationTypeDef:
return {
...
}
```
## Dynamic type annotations
`mypy_boto3` command generates `boto3.client/resource` type annotations for
`mypy_boto3_emr` and other installed services.
```bash
# Run this command after you add or remove service packages
python -m mypy_boto3
```
Generated type annotations provide overloads for `boto3.client` and `boto3.resource`,
`boto3.Session.client` and `boto3.Session.resource` functions,
so explicit type annotations are not needed.
- `mypy` supports function overloads as expected
- `PyCharm` also supports function overloads, but consumes a lot of RAM, use carefully if you have many services installed
- `VSCode` does not currently support function overloads, use explicit type annotations
```python
# Type is discovered correctly by mypy and PyCharm
# VSCode still needs explicit type annotations
client = boto3.client("emr")
session_client = boto3.Session().client("emr")
```
