-   If the argument is a string, it must contain either a real part (in the
-   same format as for :func:`float`) or an imaginary part (in the same
-   format but with a ``'j'`` or ``'J'`` suffix), or both real and imaginary
-   parts (the sign of the imaginary part is mandatory in this case).
-   The string can optionally be surrounded by whitespaces and the round
-   parentheses ``'('`` and ``')'``, which are ignored.
-   The string must not contain whitespace between ``'+'``, ``'-'``, the
-   ``'j'`` or ``'J'`` suffix, and the decimal number.
-   For example, ``complex('1+2j')`` is fine, but ``complex('1 + 2j')`` raises
-   :exc:`ValueError`.
-   More precisely, the input must conform to the :token:`~float:complexvalue`
-   production rule in the following grammar, after parentheses and leading and
-   trailing whitespace characters are removed:

+    (1.23+0j)

+
+.. productionlist:: float
+   complexvalue: `floatvalue` |
+                : `floatvalue` ("j" | "J") |
+                : `floatvalue` `sign` `absfloatvalue` ("j" | "J")

-      complexvalue: `floatvalue` |

-                  : `floatvalue` `sign` `absfloatvalue` ("j" | "J")
 
    If the argument is a number, the constructor serves as a numeric
    conversion like :class:`int` and :class:`float`.
