    the function serves as a numeric conversion function like :func:`int`,
    :func:`long` and :func:`float`.  If both arguments are omitted, returns ``0j``.
 
+   .. note::
+
+      When converting from a string, the string must not contain whitespace
+      around the central ``+`` or ``-`` operator.  For example,
+      ``complex('1+2j')`` is fine, but ``complex('1 + 2j')`` raises
+      :exc:`ValueError`.

    The complex type is described in :ref:`typesnumeric`.
