Hallo,
from a SQLite database I get a value by SELECT s from... which normaly
is a string, but can be the NULL value, wich means it is not defined. To
put the value into a form (made by QT) I need a string representation.
str(s) gives either the string itself (which is good) or "None" (which
is not so good) in the case of NULL. Instead of "None" I would prefer an
empty string "". How to get that?
Possibly there is a build in function smart(s1, s2, s3,...) which
returns the first s which is a useable string, or even "" if there isn't
any string in the arguments?
Thanks for help
