Hi everybody,

After a scan of the messages in this group, it seems there is nothing

That list of allowable values for data entry is just one part of the
Data Validity (aka Validation) functionality, none of which is
implemented in xlwt.

Hi John,

Thx for the reply first.

click a cell, then move to Data, choose Validity, in Validity has
three tabs, first one is called "Criteria",
in Criteria tab, select "list" in Allow section, then start enter
Entries.

"validity criteria selection list" isn't something I've heard of before.
If you mean what you get in the Excel user interface when you do
Data/Filter/AutoFilter, the answer is "no".
If you mean something else, it would help if you were to tell us how
such a thing is created by a user with the Excel user interface. The

In this case, we do have a patch, provided by Rob Burton -- se the
thread titled "Multiple formats in a cell" around early March 2009. Note
that a patch is a diff file to apply to the xlwt source. That's not all
that's required; it needs (a) documentation [more than most, because one
would go nuts deriving the docs from the diff] and (b) very solid

not? Because none of them are for the latest version of the package; the

it's version 0.3a1.

What is *the* unix box folder that you refer to?
That's not the name of a file, it's a pattern that matches Workbook.py
and Worksheet.py. These are the names of two files in the xlwt source.
You would find these on the unix box in PPPP/lib/site-packages/xlwt
where PPP is the Python installation path.
