Inline configuration

Mypy supports setting per-file configuration options inside files themselves using # mypy: comments. For example:

# mypy: disallow-any-generics

Inline configuration comments take precedence over all other configuration mechanisms.

Configuration comment format

Flags correspond to :ref:`config file flags <config-file>` but allow hyphens to be substituted for underscores.

Values are specified using =, but = True may be omitted:

# mypy: disallow-any-generics
# mypy: always-true=FOO

Multiple flags can be separated by commas or placed on separate lines. To include a comma as part of an option's value, place the value inside quotes:

# mypy: disallow-untyped-defs, always-false="FOO,BAR"

Like in the configuration file, options that take a boolean value may be inverted by adding no- to their name or by (when applicable) swapping their prefix from disallow to allow (and vice versa):

# mypy: allow-untyped-defs, no-strict-optional
