*How to Download a File from AWS S3 Using Python*

In this tutorial, we walk you through the process of downloading a file from an AWS S3 bucket to your local machine using Python. We will use Python's Boto3 library and the OS library to download a file and store it in your Downloads folder.

*Step-by-Step Guide:*

1. **Setting Up the Environment**: Learn how to set up your Python environment, including initializing the S3 client using Boto3 and defining your variables for the S3 bucket and file.

2. **Downloading the File from S3**: Understand how to download a file from your S3 bucket using the `download_file` method. We'll specify the S3 bucket, file name (key), and the local directory where the file will be saved.

3. **Listing Files in the Downloads Folder**: We demonstrate how to list the contents of your local Downloads directory after the download to confirm that the file has been successfully saved.

4. **Code Explanation**: Walk through the Python code to ensure you understand each part of the process for downloading files from S3.

*Code Breakdown:*

```python
import boto3
import os

Instantiate S3 client
client = boto3.client('s3')

Set bucket name and file details
bucket = 'your_bucket_name'
key = 'profiles_007.csv' # The file in S3 you want to download
file_name = os.path.join(os.path.expanduser("~"), "Downloads", "profiles_007.csv")

Download the file from S3 to local Downloads folder
client.download_file(bucket, key, file_name)

List contents of Downloads folder to confirm download
downloads_dir = os.path.join(os.path.expanduser("~"), "Downloads")
for root, dirs, files in os.walk(downloads_dir):
for fn in files:
print(fn)
```
