Inline comments can increase costs
x = y + z # This is a trailing comment that can become hard to read.
# A comment before the actual code, is better readable x = y + z
Why you should care
According to PEP8, trailing comments can be used but sparsely. To make your code readable, comments should be placed in a separate line, before the actual code. This ensures your comment is always visible and properly formatted.
