| 1918 The repeat variable | |
| 1919 ~~~~~~~~~~~~~~~~~~~ | |
| 1920 | |
| 1921 The repeat variable holds an entry for each active iteration. That is, if | |
| 1922 you have a ``tal:repeat="user db/users"`` command, then there will be a | |
| 1923 repeat variable entry called "user". This may be accessed as either:: | |
| 1924 | |
| 1925 repeat/user | |
| 1926 python:repeat['user'] | |
| 1927 | |
| 1928 The "user" entry has a number of methods available for information: | |
| 1929 | |
| 1930 =============== ========================================================= | |
| 1931 Method Description | |
| 1932 =============== ========================================================= | |

| 1934 last True if the current item is the last in the sequence. | |
| 1935 even True if the current item is an even item in the sequence. | |
| 1936 odd True if the current item is an odd item in the sequence. | |
| 1937 number Current position in the sequence, starting from 1. | |
| 1938 letter Current position in the sequence as a letter, a through | |
| 1939 z, then aa through zz, and so on. | |
