No newline at end of file (W292)
Files should end with a newline.
Anti-pattern
Imagine the example below is an entire file.
import os
BASE_DIR = os.path.dirname(os.path.abspath(__file__))
Best practice
Imagine the example below is an entire file.
import os
BASE_DIR = os.path.dirname(os.path.abspath(__file__))
# This is a new line that ends the file.
