The main operations on a dictionary are storing a value with some key and

This change is specified in:pep:`765`.

940+
In situations where this change is inconvenient (such as those where the
941+
warnings are redundant due to code linting), the:ref:`warning filter
942+
<warning-filter>` can be used to turn off all syntax warnings by adding
943+
``ignore::SyntaxWarning`` as a filter. This can be specified in combination
944+
with a filter that converts other warnings to errors (for example, passing
945+
``-Werror -Wignore::SyntaxWarning`` as CLI options, or setting
946+
``PYTHONWARNINGS=error,ignore::SyntaxWarning``).
947+
948+
Note that applying such a filter at runtime using the:mod:`warnings` module
949+
will only suppress the warning in code that is compiled *after* the filter is
950+
adjusted. Code that is compiled prior to the filter adjustment (for example,
951+
when a module is imported) will still emit the syntax warning.
