class_docstr: Integer ring based on Python's ``int`` type.
  
  This will be used as :ref:`ZZ` if ``gmpy`` and ``gmpy2`` are not
  installed. Elements are instances of the standard Python ``int`` type.
docstr: Compute square root of ``a``. 
docstr_tok: ["Compute","square","root","of","``","a","``","."]
code: def sqrt(self, a):
      """Compute square root of ``a``."""
      return python_sqrt(a)
