+## Common operations
+
+#### S3 Operations
+
+```python
+import boto3
+
+# Initialize the S3 client
+s3 = boto3.client('s3')
+
+# List buckets
+response = s3.list_buckets()
+buckets = [bucket['Name'] for bucket in response['Buckets']]
+
+# Create bucket
+s3.create_bucket(Bucket='bucket_name')
+
+# Delete bucket
+s3.delete_bucket(Bucket='bucket_name')
+
+# Upload file to bucket
+with open('file.txt', 'rb') as file:
+    s3.upload_fileobj(file, 'bucket_name', 'file.txt')
+
+# Download file from bucket
+with open('downloaded_file.txt', 'wb') as file:
+    s3.download_fileobj('bucket_name', 'file.txt', file)
+
+# List objects in bucket
+response = s3.list_objects_v2(Bucket='bucket_name')
+objects = [obj['Key'] for obj in response['Contents']]
+
+# Delete object from bucket
+s3.delete_object(Bucket='bucket_name', Key='file.txt')
+
+# Copy object within bucket
+s3.copy_object(Bucket='bucket_name', CopySource='bucket_name/file.txt', Key='file_copy.txt')
+
+# Get presigned URL for object
+url = s3.generate_presigned_url('get_object', Params={'Bucket': 'bucket_name', 'Key': 'file.txt'}, ExpiresIn=3600)
+print(url)
+
+```
+
+#### EC2 Operations
+
+```python
+# List instances
+instances = [instance.id for instance in resource.instances.all()]
+
+# Start instance
+instance_id = 'your_instance_id'
+instance = resource.Instance(instance_id)
+instance.start()
+
+# Stop instance
+instance.stop()
+
+# Terminate instance
+instance.terminate()
+```
+
+#### Lambda Operations
+
+```python
+# List functions
+functions = [func['FunctionName'] for func in client.list_functions()['Functions']]
