weird str error

[daved170]

Hi everybody,
I'm using SPE 0.8.3.c as my python editor.
I'm using the str() function and i got a very odd error.

I'm trying to do this: print str("HI")
When i'm writing this line in the shell it prints: HI
When it's in my code (it's the only line) i'm getting the following
error:

file "c:\Python25\lib\local.py" line 242, in str
return format("%.12g",val)

file "c:\Python25\lib\local.py" line 145, in format
formatted = percent % value
TypeError, float argument required

any idea? It's worked for the entire day and unfortunately when i
started my testing it raised this erroe/

local.py or locale.py? If the latter you are probably doing a star import:

from locale import *

This will replace the builtin str() with locale.str() which indeed requires
a float:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.5/locale.py", line 244, in str
return format("%.12g", val)
File "/usr/lib/python2.5/locale.py", line 147, in format
formatted = percent % value
TypeError: float argument required

As a general rule use the standard import

import locale

and then invoke the module's functions with an explicit prefix:

locale.setlocale(...)

It's a bit more to type, but it will save you a lot of trouble.

PS: When str() is the builtin str("HI") converts a string into a string
which does not make much sense.

I should start by asking why you're using using str() on a string
literal? It would seem to just be a waste of time to convert a string
to a string.

Next, I'll have to insist that you copy/paste your error messages to the
email; by retyping it you got the wrong file name. The file with that
line in it is locale.py

So now, you have a *locale* problem. Somebody other than I will have to
help. And all the effort I put in before noticing your typo is wasted.

You'd better describe your environment more thoroughly. Python version,
OS, locale, and just how you're running this script. You said it's "the
only line" so are you omitting the shebang line? Perhaps you're running
on Windows? If so, you can copy from a cmd window using
right-click-drag, at least if Quick-Edit is on.

Hi Peter,
Thanks for your answer.
I'll clearify myself. I'm using QString cause I have a GUI app. I want
to convert it to python string. It works well for several month and
suddenly two days ago it didn't. I'm not using localE at all (i'm not
importing it).
After your answer I tried it but it still didn't work.
Any other ideas?
Thanks

You mean you don't have any star imports in the module causing error?

Any other ideas?

Run your script from the command line (not your editor). Then give the
complete traceback.

Grep through the libraries you use for 'from locale' and 'import locale' to
identify the one that uses the locale module. You can identify modules used
by your script by running

python -v script.py

Aside: if you use a version control system and check in frequently it gets
easier to identify a modification that introduced an error. Highly
recommended.
