        Many of these arguments duplicate and override values that can be
        provided in a configuration file.  Parameters that are missing here
        will use values from the config file.

        `data_file` is the base name of the data file to use. The config value
        defaults to &quot;.coverage&quot;.  None can be provided to prevent writing a data
        file.  `data_suffix` is appended (with a dot) to `data_file` to create
        the final file name.  If `data_suffix` is simply True, then a suffix is
        created with the machine and process identity included.

        `cover_pylib` is a boolean determining whether Python code installed
        with the Python interpreter is measured.  This includes the Python
        standard library and any packages installed with the interpreter.

        If `auto_data` is true, then any existing data file will be read when
        coverage measurement starts, and data will be saved automatically when
        measurement stops.

        If `timid` is true, then a slower and simpler trace function will be
        used.  This is important for some environments where manipulation of
        tracing functions breaks the faster trace function.

        If `branch` is true, then branch coverage will be measured in addition
        to the usual statement coverage.

        `config_file` determines what configuration file to read:

            * If it is &quot;.coveragerc&quot;, it is interpreted as if it were True,
              for backward compatibility.

            * If it is a string, it is the name of the file to read.  If the
              file can't be read, it is an error.

            * If it is True, then a few standard files names are tried
              (&quot;.coveragerc&quot;, &quot;setup.cfg&quot;, &quot;tox.ini&quot;).  It is not an error for
              these files to not be found.

            * If it is False, then no configuration file is read.

        `source` is a list of file paths or package names.  Only code located
        in the trees indicated by the file paths or package names will be
        measured.

        `source_pkgs` is a list of package names. It works the same as
        `source`, but can be used to name packages where the name can also be
        interpreted as a file path.

        `include` and `omit` are lists of file name patterns. Files that match
        `include` will be measured, files that match `omit` will not.  Each
        will also accept a single string argument.

        `debug` is a list of strings indicating what debugging information is
        desired.

        `concurrency` is a string indicating the concurrency library being used
        in the measured code.  Without this, coverage.py will get incorrect
        results if these libraries are in use.  Valid strings are &quot;greenlet&quot;,
        &quot;eventlet&quot;, &quot;gevent&quot;, &quot;multiprocessing&quot;, or &quot;thread&quot; (the default).
        This can also be a list of these strings.

        If `check_preimported` is true, then when coverage is started, the
        already-imported files will be checked to see if they should be
        measured by coverage.  Importing measured files before coverage is
        started can mean that code is missed.

        `context` is a string to use as the :ref:`static context
        &lt;static_contexts&gt;` label for collected data.

        If `messages` is true, some messages will be printed to stdout
        indicating what is happening.

            The `concurrency` parameter.

        .. versionadded:: 4.2

        selected.

        As a special case, an `option_name` of ``&quot;paths&quot;`` will return an
        dictionary with the entire ``[paths]`` section value.

        option name.  For example, the ``branch`` option in the ``[run]``
        section of the config file would be indicated with ``&quot;run:branch&quot;``.

        `value` is the new value for the option.  This should be an
        appropriate Python value.  For example, use True for booleans, not the
        string ``&quot;True&quot;``.

        As an example, calling:

        .. code-block:: python

            cov.set_option(&quot;run:branch&quot;, True)

        missing will be included in the report.  If `ignore_errors` is true,
        then a failure while reporting a single file will not stop the entire
        report.

        `file` is a file-like object, suitable for writing.

        `output_format` determines the format, either &quot;text&quot; (the default),
        &quot;markdown&quot;, or &quot;total&quot;.

        `include` is a list of file name patterns.  Files that match will be
        included in the report. Files matching `omit` will not be included in
        the report.

        If `skip_covered` is true, don't report on files with 100% coverage.

        If `skip_empty` is true, don't report on empty files (those that have
        no statements).

        `contexts` is a list of regular expression strings.  Only data from
        :ref:`dynamic contexts &lt;dynamic_contexts&gt;` that match one of those
        expressions (using :func:`re.search &lt;python:re.search&gt;`) will be
        included in the report.

        `precision` is the number of digits to display after the decimal
        point for percentages.

        All of the arguments default to the settings read from the
        :ref:`configuration file &lt;config&gt;`.
