        ## Overview
        
        The IBM Cloudant Python SDK allows developers to programmatically interact with IBM Cloudant with the help of `ibmcloudant` package.
        
        ## Features
        
        The purpose of this Python SDK is to wrap most of the HTTP request APIs provided by Cloudant and
        supply other functions to ease the usage of Cloudant.
        This SDK should make life easier for programmers to do what’s really important for them: develop.
        
        Reasons why you should consider using Cloudant Python SDK in your project:
        
        - Supported by IBM Cloudant.
        - Includes all the most popular and latest supported endpoints for applications.
        - Handles the authentication.
        - Familiar user experience of IBM Cloud SDKs.
        - Instances of the client are unconditionally thread-safe.
        
        ## Prerequisites
        
        [ibm-cloud-onboarding]: https://cloud.ibm.com/registration
        
        - An [IBM Cloud][ibm-cloud-onboarding] account.
        - An IAM API key to allow the SDK to access your account. Create one [here](https://cloud.ibm.com/iam/apikeys).
        - Python 3.5.3 or above.
        
        ## Installation
        
        To install, use `pip` or `easy_install`:
        
        ```bash
        pip install --upgrade "ibmcloudant>=0.0.26"
        ```
        
        or
        
        ```bash
        easy_install --upgrade "ibmcloudant>=0.0.26"
        ```
        
        ## Getting started
        
        ### Authentication
        
        This library requires some of your [Cloudant service credentials](https://cloud.ibm.com/docs/Cloudant?topic=cloudant-creating-an-ibm-cloudant-instance-on-ibm-cloud#locating-your-service-credentials) to authenticate with your account.
        
        1. `IAM`, `COUCHDB_SESSION`, `BASIC` or `NOAUTH` **authentication type**.
            1. [*IAM authentication*](#iam-authentication) is highly recommended when your back-end database server is [**Cloudant**](https://cloud.ibm.com/docs/Cloudant?topic=cloudant-ibm-cloud-identity-and-access-management-iam-). This authentication type requires a server-generated `apikey` instead of a user-given password.
            1. [*Session cookie (`COUCHDB_SESSION`) authentication*](#session-cookie-authentication) is recommended for [Apache CouchDB](https://docs.couchdb.org/en/stable/api/server/authn.html#cookie-authentication) or for [Cloudant](https://cloud.ibm.com/docs/Cloudant?topic=cloudant-authentication#cookie-authentication) when IAM is unavailable. It exchanges username and password credentials for an `AuthSession` cookie from the `/_session` endpoint.
            1. [*Basic* (or legacy) *authentication*](#basic-authentication) is a fallback for both [Cloudant](https://cloud.ibm.com/docs/services/Cloudant/api?topic=cloudant-authentication#basic-authentication) and [Apache CouchDB](https://docs.couchdb.org/en/stable/api/server/authn.html#basic-authentication) back-end database servers. This authentication type requires the good old `username` and `password` credentials.
            1. *Noauth* authentication does not need any credentials. Note that this authentication type will only work for queries against a database with read access for everyone.
        1. The service `url`
        
        You have to add these properties as your **environment variables**, because some
        examples that follow assume that these variables are set.
        To learn more about authentication configuration see the related documentation in the
        [Cloudant API docs](https://cloud.ibm.com/apidocs/cloudant#authentication?code=python) or in the
        [general SDK usage information](https://github.com/IBM/ibm-cloud-sdk-common#authentication).
        
        #### IAM authentication
        
        For Cloudant *IAM authentication* set the following environmental variables by replacing `<url>` and `<apikey>` with your proper [service credentials](https://cloud.ibm.com/docs/Cloudant?topic=cloudant-creating-an-ibm-cloudant-instance-on-ibm-cloud#locating-your-service-credentials). There is no need to set `CLOUDANT_AUTH_TYPE` to `IAM` because it is the default.
        
        ```bash
        CLOUDANT_URL=<url>
        CLOUDANT_APIKEY=<apikey>
        ```
        
        #### Session cookie authentication
        
        For `COUCHDB_SESSION` authentication set the following environmental variables by replacing `<url>`, `<username>` and `<password>` with your proper [service credentials](https://cloud.ibm.com/docs/Cloudant?topic=cloudant-creating-an-ibm-cloudant-instance-on-ibm-cloud#locating-your-service-credentials).
        
        ```bash
        CLOUDANT_AUTH_TYPE=COUCHDB_SESSION
        CLOUDANT_URL=<url>
        CLOUDANT_USERNAME=<username>
        CLOUDANT_PASSWORD=<password>
        ```
        
        #### Basic authentication
        
        For *Basic authentication* set the following environmental variables by replacing `<url>`, `<username>` and `<password>` with your proper [service credentials](https://cloud.ibm.com/docs/Cloudant?topic=cloudant-creating-an-ibm-cloudant-instance-on-ibm-cloud#locating-your-service-credentials).
        
        ```bash
        CLOUDANT_AUTH_TYPE=BASIC
        CLOUDANT_URL=<url>
        CLOUDANT_USERNAME=<username>
        CLOUDANT_PASSWORD=<password>
        ```
        
        **Note**: We recommend using [IAM](#iam-authentication) for Cloudant and
        [Session](#session-cookie-authentication) for CouchDB authentication.
        
        ### Code examples
        
        #### 1. Retrieve information from an existing database
        
        This example code gathers some information about an existing database hosted on the https://examples.cloudant.com/ service `url`.
        To do this, you need to extend your environment variables with the *service url* and *authentication type* to use `NOAUTH` authentication while reaching the `animaldb` database. This step is necessary for the SDK to distinguish the `EXAMPLES` custom service name from the default service name which is `CLOUDANT`.
        
        ```bash
        EXAMPLES_URL=https://examples.cloudant.com
        EXAMPLES_AUTH_TYPE=NOAUTH
        ```
        
        Once the environment variables are set, you can try out the code examples.
        
        [embedmd]:# (test/examples/src/get_info_from_existing_database.py)
        ```py
        import json
        
        from ibmcloudant.cloudant_v1 import CloudantV1
        
        # 1. Create a Cloudant client with "EXAMPLES" service name ============
        examples_client = CloudantV1.new_instance(service_name="EXAMPLES")
        
        # 2. Get server information ===========================================
        server_information = examples_client.get_server_information(
        ).get_result()
        
        print(f'Server Version: {server_information["version"]}')
        
        # 3. Get database information for "animaldb" ==========================
        db_name = "animaldb"
        
        db_information = examples_client.get_database_information(
            db=db_name
        ).get_result()
        
        # 4. Show document count in database ==================================
        document_count = db_information["doc_count"]
        
        print(f'Document count in \"{db_information["db_name"]}\" '
              f'database is {document_count}.')
        
        # 5. Get zebra document out of the database by document id ============
        document_about_zebra = examples_client.get_document(
            db=db_name,
            doc_id="zebra"
        ).get_result()
        
        print(f'Document retrieved from database:\n'
              f'{json.dumps(document_about_zebra, indent=2)}')
        ```
        
        The result of the code is similar to the following output.
        
        [embedmd]:# (test/examples/output/get_info_from_existing_database.txt)
        ```txt
        Server Version: 2.1.1
        Document count in "animaldb" database is 11.
        Document retrieved from database:
        {
          "_id": "zebra",
          "_rev": "3-750dac460a6cc41e6999f8943b8e603e",
          "wiki_page": "http://en.wikipedia.org/wiki/Plains_zebra",
          "min_length": 2,
          "max_length": 2.5,
          "min_weight": 175,
          "max_weight": 387,
          "class": "mammal",
          "diet": "herbivore"
        }
        ```
        
        #### 2. Create your own database and add a document
        
        Now comes the exciting part of creating your own `orders` database and adding a document
        about *Bob Smith* with your own [IAM](#iam-authentication) or [Basic](#basic-authentication) service credentials.

            ).get_result()
            example_document.rev = document_info["_rev"]
            print(f'The document revision for {example_doc_id} document' +

        print(f'You have created the document:\n{example_document}')
        ```
        
        The result of the code is similar to the following output.
        
        [embedmd]:# (test/examples/output/create_db_and_doc.txt)

        ```
        
        #### 3. Update your previously created document
        
        **Note**: this example code assumes that you have created both the `orders` database and the `example` document by [running this previous example code](#2-create-your-own-database-and-add-a-document) successfully, otherwise you get the `Cannot update document because either "orders" database or "example" document was not found.` message.
