Hi;
I have a string.join statement on a variable that comes from a
cgi.FieldStorage().getlist. The variable may be a list or a
single value. I need to treat it differently depending on
which it is. How can I distinguish it? len(var) will obviously
give me the length of the string if it's a string and the
length of the list if it's a list.
TIA,
beno
Like this:
if isinstance(var, list):
... join ...
else:
... ??? ...
Right.. Thanks!
beno
You should definitely check again MRAB's answer.
Having getlist returning something else than a list, especially a non
iterable single item *is* suspicious.
Usually, properly designed functions return consistent types over calls.
