operation with strings and numbers

[Hellas]

Hello guy
I'm italian boy, I need help for doing a strange thing with numbers

I have a number from operation like this:
a = float("010.123")
b = float("001.124")
p= a*b
p="%06.3f" % p
the resulted is "_11,278" where "_" is a space
I must to change the formatting of this number in "011278" but I don't known
what to do
Could you help me please?
thanks a lot

I suggest you read this:

http://www.catb.org/~esr/faqs/smart-questions.html

And then read this:

http://www.python.org/doc/2.3.4/lib/...q-strings.html

If you still can't figure it out, use the hints in the first document
and ask again.

So you want to replace the any space with a '0' and get rid
of the ',' (in this case the decimal sign because you're
using an Italian locale, as compared to my US use of '.')

Try this

s = " 11,278"
s.replace(" ", "0") '011,278' s.replace(" ", "0").replace(",", "") '011278'
Another solution is to use the 'zfill' method of strings.
s = "%6.3f" % p
s '11.378' s.replace(".", "").zfill(6) '011378'

There are two things that you need to do: fix the format string, and
process the string after the conversion is made. Assuming you want to
do (1), there is a very simple mistake to fix. Try this:

"%07.3f" % p '011.378'

Instead of "06", use "07" -- remember that you have to count the "."
in the floating point representation. After you've done that, remove
the "." from the resulting string, by replacing it with a empty
string:

s = "%07.3f" % p
s = s.replace(".","")

If you want to do everything into a single line, then just do it:

s = ("%07.3f" % p).replace(".","")

Another option is to convert the floating point number to a integer
*before* formatting:
"%06d" % int(p*1000)

'011378'

Did you mean Italian SCHOOLboy, be any chance? Don't be afraid to say
so, because everyone can guess anyway.

No, it isn't.

In [6]: "%06.3f" % p
Out[6]: '11.378'
In [7]: "%07.3f" % p
Out[7]: '011.378'

In [8]: "lunttaus".replace("t","")

May I suggest newsgroup it.comp.lang.python -- there, we talk about
Python in Italian.

Posso suggerire il gruppo it.comp.lang.python in cui parliamo di Python
in Italiano.

Sorry but It doesn't exist

You probably mean your ISP (flashnet) doesn't carry it. It's obviously
wrong for any Italian ISP to fail to carry the entire it.* official
hierarchy -- protest with them. Meanwhile, you can use Google Groups or
other non-NNTP hacks to read and write on it.comp.lang.python -- or
freely join "Individual Net", see <http://www.individual.net/> for
registration (I've done that because I travel so much that getting news
from any given ISP is impractical -- I previously used cheap
newsguy.com, but individual.net is completely free, and free's better
than cheap).
