2.6 Delimiters
</H1>

<P>
The following tokens serve as delimiters in the grammar:

<P>
<div class="verbatim"><pre>
(       )       [       ]       {       }      @
,       :       .       `       =       ;
+=      -=      *=      /=      //=     %=
&amp;=      |=      ^=      &gt;&gt;=     &lt;&lt;=     **=
</pre></div>

<P>
The period can also occur in floating-point and imaginary literals.  A
sequence of three periods has a special meaning as an ellipsis in slices.
The second half of the list, the augmented assignment operators, serve
lexically as delimiters, but also perform an operation.

<P>
The following printing ASCII characters have special meaning as part
of other tokens or are otherwise significant to the lexical analyzer:

<P>
<div class="verbatim"><pre>
'       "       #       \
</pre></div>

<P>
The following printing ASCII characters are not used in Python.  Their
occurrence outside string literals and comments is an unconditional
error:

<P>
<div class="verbatim"><pre>
$       ?
</pre></div>
