Hi,
Pandas syntax seems very nice (short), and popular ...
But Pandas eat RAM..., and well, most of data is in DB...
so I wonder, how hard would it be to overload operators to use pyDAL (or
other DAL/ORM)?
what are the main challanges?

Now I have an error like this one:
RecursionError: maximum recursion depth exceeded while calling a Python object
...and I have no idea how to debug it, since I'm not using any recursion in
my code. I suspect it's an issue with the module or modules (not written by
me) I'm using, but I can't t
I am very sorry, I need to be more careful with my replies.
I wasn't sure if random needed to be imported but it looks like it does. So:
import random
rows = db(db.person.id>0).select()
random_number = random.randrange(0, len(rows))
row = rows[random_number]
return row

Is the typo just in your post, or in the code you are trying? (Remove
space between "random" and "_number").

Hello,
I've started using python3 with web2py and it has saved me a lot of
encoding headaches.
However, the traceback Tickets in web2py are not as comprehensive as those
in python2 with web2py. They look like:
'dict' object has no attribute 'content'Version
web2py™ Version 2.16.1-stable+times
Thanks. Doing that already.

Are you querying multiple table?? You can do a join... That way you will
have all the value for every fields the only catch is that when you join to
disambiguate fields names dal use table.field instead of just field as
field name so it migth happen that if you call "manually" vs
"programmatically"
Thanks.
It iterates well giving some fields data, but not all as needed. I get data
from some 4 fields only. I have about 60 in some db. Plus there is this:

Should be
for f, v in row.iteritems():
k, v for key, value, but I use f instead of k because you will have
field_name and value in this for loop...

You don’t need to use sqlexecute(), insert can handle multiple fields. But you
do need to separate them with comma. In the field definitions you need to add
the field type otherwise the default type is assumed (string). See the DAL
documentation for details.

Thank you, as I understand web2py function INSERT have only one argument
and if I want to pass 2 or more variables I should use something else?
I have read about executesql and use it for inserting some variables like
that: db.executesql('INSERT INTO table (var1, var2, var3) VALUES (1, 2, 3)')
