## How to install
Install `boto3-stubs` for `Lambda` service.
```bash
python -m pip install boto3-stubs[lambda]
```
## Usage
### VSCode
- Install [Python extension](https://marketplace.visualstudio.com/items?itemName=ms-python.python)
- Install [Pylance extension](https://marketplace.visualstudio.com/items?itemName=ms-python.vscode-pylance)
- Set `Pylance` as your Python Language Server
- Install `boto-stubs[lambda]` in your environment: `python -m pip install 'boto3-stubs[lambda]'`
Both type checking and auto-complete should work for `Lambda` service.
No explicit type annotations required, write your `boto3` code as usual.
### PyCharm
- Install `boto-stubs[lambda]` in your environment: `python -m pip install 'boto3-stubs[lambda]'`
Both type checking and auto-complete should work for `Lambda` service.
No explicit type annotations required, write your `boto3` code as usual.
Auto-complete can be slow on big projects or if you have a lot of installed `boto3-stubs` submodules.
### Other IDEs
Not tested, but as long as your IDE support `mypy` or `pyright`, everything should work.
### mypy
- Install `mypy`: `python -m pip install mypy`
- Install `boto-stubs[lambda]` in your environment: `python -m pip install 'boto3-stubs[lambda]'`
- Run `mypy` as usual
Type checking should work for `Lambda` service.
No explicit type annotations required, write your `boto3` code as usual.
### pyright
- Install `pyright`: `yarn global add pyright`
- Install `boto-stubs[lambda]` in your environment: `python -m pip install 'boto3-stubs[lambda]'`
- Optionally, you can install `boto3-stubs` to `typings` folder.
Type checking should work for `Lambda` service.
No explicit type annotations required, write your `boto3` code as usual.
## Explicit type annotations
### Client annotations
`LambdaClient` provides annotations for `boto3.client("lambda")`.
```python
import boto3
from mypy_boto3_lambda import LambdaClient
client: LambdaClient = boto3.client("lambda")
# 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: LambdaClient = session.client("lambda")
```
### Paginators annotations
`mypy_boto3_lambda.paginator` module contains type annotations for all paginators.
```python
from mypy_boto3_lambda import LambdaClient
from mypy_boto3_lambda.paginator import (
ListAliasesPaginator,
ListCodeSigningConfigsPaginator,
ListEventSourceMappingsPaginator,
ListFunctionEventInvokeConfigsPaginator,
ListFunctionsPaginator,
ListFunctionsByCodeSigningConfigPaginator,
ListLayerVersionsPaginator,
ListLayersPaginator,
ListProvisionedConcurrencyConfigsPaginator,
ListVersionsByFunctionPaginator,
)
client: LambdaClient = boto3.client("lambda")
# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
list_aliases_paginator: ListAliasesPaginator = client.get_paginator("list_aliases")
list_code_signing_configs_paginator: ListCodeSigningConfigsPaginator = client.get_paginator("list_code_signing_configs")
list_event_source_mappings_paginator: ListEventSourceMappingsPaginator = client.get_paginator("list_event_source_mappings")
list_function_event_invoke_configs_paginator: ListFunctionEventInvokeConfigsPaginator = client.get_paginator("list_function_event_invoke_configs")
list_functions_paginator: ListFunctionsPaginator = client.get_paginator("list_functions")
list_functions_by_code_signing_config_paginator: ListFunctionsByCodeSigningConfigPaginator = client.get_paginator("list_functions_by_code_signing_config")
list_layer_versions_paginator: ListLayerVersionsPaginator = client.get_paginator("list_layer_versions")
list_layers_paginator: ListLayersPaginator = client.get_paginator("list_layers")
list_provisioned_concurrency_configs_paginator: ListProvisionedConcurrencyConfigsPaginator = client.get_paginator("list_provisioned_concurrency_configs")
list_versions_by_function_paginator: ListVersionsByFunctionPaginator = client.get_paginator("list_versions_by_function")
```
### Waiters annotations
`mypy_boto3_lambda.waiter` module contains type annotations for all waiters.
```python
from mypy_boto3_lambda import LambdaClient
from mypy_boto3_lambda.waiter import (
FunctionActiveWaiter,
FunctionExistsWaiter,
FunctionUpdatedWaiter,
)
client: LambdaClient = boto3.client("lambda")
# Explicit type annotations are optional here
# Type should be correctly discovered by mypy and IDEs
# VSCode requires explicit type annotations
function_active_waiter: FunctionActiveWaiter = client.get_waiter("function_active")
function_exists_waiter: FunctionExistsWaiter = client.get_waiter("function_exists")
function_updated_waiter: FunctionUpdatedWaiter = client.get_waiter("function_updated")
```
### Typed dictionations
`mypy_boto3_lambda.type_defs` module contains structures and shapes assembled
to typed dictionaries for additional type checking.
```python
from mypy_boto3_lambda.type_defs import (
AccountLimitTypeDef,
AccountUsageTypeDef,
AliasConfigurationTypeDef,
AliasRoutingConfigurationTypeDef,
AllowedPublishersTypeDef,
CodeSigningConfigTypeDef,
CodeSigningPoliciesTypeDef,
ConcurrencyTypeDef,
DeadLetterConfigTypeDef,
DestinationConfigTypeDef,
EnvironmentErrorTypeDef,
EnvironmentResponseTypeDef,
EventSourceMappingConfigurationTypeDef,
FileSystemConfigTypeDef,
FunctionCodeLocationTypeDef,
FunctionConfigurationTypeDef,
FunctionEventInvokeConfigTypeDef,
ImageConfigErrorTypeDef,
ImageConfigResponseTypeDef,
ImageConfigTypeDef,
LayerTypeDef,
LayerVersionContentOutputTypeDef,
LayerVersionsListItemTypeDef,
LayersListItemTypeDef,
OnFailureTypeDef,
OnSuccessTypeDef,
ProvisionedConcurrencyConfigListItemTypeDef,
ResponseMetadata,
SelfManagedEventSourceTypeDef,
SourceAccessConfigurationTypeDef,
TracingConfig
