2.5 运算符 Operators

The following tokens are operators:

以下符号是运算符:

+       -       *       **      /       //      %
<<      >>      &       |       ^       ~
<       >       <=      >=      ==      !=      <>

The comparison operators <> and != are alternate spellings of the same operator. != is the preferred spelling; <> is obsolescent.

比较运算符<>和!=是可选的两个具有相同含义的符号. 但推荐使用!=, <>是过时的写法.

2.6 分隔符 Delimiters

The following tokens serve as delimiters in the grammar:

以下符号用作语法上的分隔符:

(       )       [       ]       {       }
,       :       .       `       =       ;
+=      -=      *=      /=      //=     %=
&=      |=      ^=      >>=     <<=     **=

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.

句号可以在浮点数和虚数字面值中出现, 一个连续的三个句号的序列具有特殊的含义, 它指出这是一个片断中的省略写法.在这个表格的后半部分, 即参数化赋值运算符, 在词法上是作为分隔符处理, 但也执行运算.

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

以下可显示ASCII字符具有作为其它符号的一部分有着特殊的含义, 或者对于词法分析器具有重要意义:

'       "       #       \

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

以下可显示ASCII字符不在Python中使用, 当它们出现在注释和字面值之外时就是非法的:

@       $       ?
