parameters: (dates, weekmask=None, holidays=None, busdaycal=None, out=None)
return_statement: return (dates, weekmask, holidays, out)
docstring: is_busday(dates, weekmask='1111100', holidays=None, busdaycal=None, out=None)
  
      Calculates which of the given dates are valid days, and which are not.
  
      .. versionadded:: 1.7.0
  
      Parameters
      ----------
      dates : array_like of datetime64[D]
          The array of dates to process.
      weekmask : str or array_like of bool, optional
          A seven-element array indicating which of Monday through Sunday are
          valid days. May be specified as a length-seven list or array, like
          [1,1,1,1,1,0,0]; a length-seven string, like '1111100'; or a string
          like "Mon Tue Wed Thu Fri", made up of 3-character abbreviations for
          weekdays, optionally separated by white space. Valid abbreviations
          are: Mon Tue Wed Thu Fri Sat Sun
      holidays : array_like of datetime64[D], optional
          An array of dates to consider as invalid dates.  They may be
          specified in any order, and NaT (not-a-time) dates are ignored.
          This list is saved in a normalized form that is suited for
          fast calculations of valid days.
      busdaycal : busdaycalendar, optional
          A `busdaycalendar` object which specifies the valid days. If this
          parameter is provided, neither weekmask nor holidays may be
          provided.
      out : array of bool, optional
          If provided, this array is filled with the result.
  
      Returns
      -------
      out : array of bool
          An array with the same shape as ``dates``, containing True for
          each valid day, and False for each invalid day.
  
      See Also
      --------
      busdaycalendar: An object that specifies a custom set of valid days.
      busday_offset : Applies an offset counted in valid days.
      busday_count : Counts how many valid days are in a half-open date range.
  
      Examples
      --------
      >>> # The weekdays are Friday, Saturday, and Monday
      ... np.is_busday(['2011-07-01', '2011-07-02', '2011-07-18'],
