no-space-after-block-comment (E265)#

Derived from the pycodestyle linter.

Fix is always available.

This rule is unstable and in preview. The --preview flag is required for use.

What it does#

Checks for block comments that lack a single space after the leading # character.

Why is this bad?#

Per PEP 8, "Block comments generally consist of one or more paragraphs built out of complete sentences, with each sentence ending in a period."

Block comments should start with a # followed by a single space.

Shebangs (lines starting with #!, at the top of a file) are exempt from this rule.


#Block comment

Use instead:

# Block comment
