S3 file path description

Question

Hi All  
I'm trying to follow this tutorial: https://medium.com/swlh/upload-binary-files-to-s3-using-aws-api-gateway-with-aws-lambda-2b4ba8c70b8e  
  
I'm not clear about the code line:  file_path = 'YOUR_FILE_PATH_HERE'  
Is this the path to the S3 folder?  
If so, how do I find this, or what is it's format?  
  
code example:  
import json  
import base64  
import boto3  
BUCKET_NAME = 'YOUR_S3_BUCKET_NAME_HERE'  
def lambda_handler(event, context):  
    file_content = base64.b64decode(event\['content'])  
    **file_path = 'YOUR_FILE_PATH_HERE'**  
    s3 = boto3.client('s3')  
    try:  
        s3_response = s3.put_object(Bucket=BUCKET_NAME, Key=file_path, Body=file_content)  
    except Exception as e:  
        raise IOError(e)  
    return {  
        'statusCode': 200,  
        'body': {  
            'file_path': file_path  
        }  
    }

Hi,   
the value you specify here is the "object name" (i.e. Key) in the S3 bucket.  The "object name" can include "folders" as part of the "key".  
  
For example, if you have a bucket called "example-bucket", and you specified

```
file_path='myDog.jpg' 
s3.put_object(Bucket=BUCKET_NAME, Key=file_path, Body=file_content)
```

If you viewed your bucket in the AWS S3 console, you would see 'myDog.jpg' as a top level object.  
You could also include "folders". For example:

```
file_path='pets/mydog.jpg'
s3.put_object(Bucket=BUCKET_NAME, Key=file_path, Body=file_content)
```

Now, if you want to your AWS S3 console, and opened your bucket, you would see a "folder" called pets. If you clicked on the "pets folder", you would then see myDog.jpg.  
  
Hope this helps,
