I also had the same issue,it can be solved by creating a config and credential file in the home directory. Below show the steps I did to solve this issue.

Create a config file :

touch ~/.aws/config

And in that file I entered the region

[default]
region = us-west-2

Then create the credential file:

touch ~/.aws/credentials

Then enter your credentials

[Profile1]
aws_access_key_id = XXXXXXXXXXXXXXXXXXXX 
aws_secret_access_key = YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

After set all these, then my python file to connect bucket. Run this file will list all the contents.

import boto3
import os

os.environ['AWS_PROFILE'] = "Profile1"
os.environ['AWS_DEFAULT_REGION'] = "us-west-2"

s3 = boto3.client('s3', region_name='us-west-2')
print("[INFO:] Connecting to cloud")

# Retrieves all regions/endpoints that work with S3

response = s3.list_buckets()
print('Regions:', response)
