| 60 | The following tokens serve as delimiters in the grammar: |
| 61 | |
| 62 | <P> |
| 63 | <div class="verbatim"><pre> |
| 64 | ( ) [ ] { } @ |
| 65 | , : . ` = ; |
| 66 | += -= *= /= //= %= |
| 67 | &= |= ^= >>= <<= **= |
| 68 | </pre></div> |
| 69 | |
| 70 | <P> |
| 71 | The period can also occur in floating-point and imaginary literals. A |
| 72 | sequence of three periods has a special meaning as an ellipsis in slices. |
| 73 | The second half of the list, the augmented assignment operators, serve |
| 74 | lexically as delimiters, but also perform an operation. |
| 75 | |
| 76 | <P> |
| 77 | The following printing ASCII characters have special meaning as part |
| 78 | of other tokens or are otherwise significant to the lexical analyzer: |
| 79 | |
| 80 | <P> |
| 81 | <div class="verbatim"><pre> |
| 82 | ' " # \ |
| 83 | </pre></div> |
| 84 | |
| 85 | <P> |
| 86 | The following printing ASCII characters are not used in Python. Their |
| 87 | occurrence outside string literals and comments is an unconditional |
| 88 | error: |
| 89 | |
