Ensure that you have an AWS account and the necessary permissions to access S3. Install the AWS Command Line Interface (CLI) and configure your credentials. Run `aws configure` and provide your AWS Access Key, Secret Key, region, and output format.

You will need the `requests` library to fetch data from Wikipedia and `boto3` to interact with AWS S3. Install these libraries using pip:
```bash
pip install requests boto3
```

Use the Wikipedia Pageviews API to fetch the desired data. This can be done using the `requests` library in Python. For example:
```python
import requests

def fetch_wikipedia_pageviews():
url = 'https://wikimedia.org/api/rest_v1/metrics/pageviews/per-article/en.wikipedia/all-access/all-agents/Python_(programming_language)/daily/20230101/20230131'
response = requests.get(url)
if response.status_code == 200:
return response.json()
else:
raise Exception("Failed to fetch data from Wikipedia API")

pageviews_data = fetch_wikipedia_pageviews()
```

Convert the fetched JSON data into a format suitable for storage (e.g., CSV or JSON string). You may use Python's `json` or `csv` modules for this. Here’s an example of converting JSON to a string:
```python
import json

def prepare_data_for_s3(data):
return json.dumps(data, indent=4)

prepared_data = prepare_data_for_s3(pageviews_data)
```

Create an S3 client using Boto3 to handle the upload of data to your bucket. Ensure you specify the correct AWS region:
```python
import boto3

s3_client = boto3.client('s3', region_name='us-west-2') # Replace with your AWS region
```

Use the `put_object` method from the S3 client to upload your data. Specify the bucket name and the object key (filename) for the data:
```python
def upload_to_s3(data, bucket_name, object_key):
s3_client.put_object(Body=data, Bucket=bucket_name, Key=object_key)

bucket_name = 'your-bucket-name' # Replace with your bucket name
object_key = 'wikipedia_pageviews.json' # File name in S3

upload_to_s3(prepared_data, bucket_name, object_key)
```

After uploading, verify that the object exists in the bucket and set the necessary permissions if the data needs to be publicly accessible. You can check the upload using the AWS Management Console or AWS CLI:
```bash
aws s3 ls s3://your-bucket-name/
```
Optionally, set the permissions on the object using the console or with a bucket policy in the AWS Management Console.

By following these steps, you can move data from Wikipedia Pageviews to S3 without relying on third-party connectors or integrations.
