Warnings ¶

The Python warnings package is part of the Python standard library and used to alert the user of a problem.

Typically these warnings are logged to the log file, but the warnings module can be configured to elevate these warnings to exceptions or to ignore them completely.

For full details of the warnings package please see the Python documentation here `https://docs.python.org/3/library/warnings.html`_.

The warnings package can be configured in the [LOG] section of the PyXLL config file with the following options.

• capture_warnings

  Write warnings to the log file.

  If this is set to 0 then warnings will not be captured and written to the log file.

  Defaults to 1.

• warnings_filters

  Warnings filters to control whether warnings are ignored, dispayed, or turned into errors.

  Multiple warning filters can be configured on multiple lines.

  Individual warnings filters are specified as a sequence of fields separated by colons:

  action:message:category:module:line
  

  Example:

  [LOG]
  warnings_filters =
      default::DeprecationWarning:__main__
      ignore::DeprecationWarning
      ignore::PendingDeprecationWarning
      ignore::ImportWarning
      ignore::ResourceWarning
