2.6 Delimiters

The following tokens serve as delimiters in the grammar:

      (       )       [       ]       {       }
      ,       :       .       `       =       ;

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

      '       "       #       \

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

      @       $       ?
