Hi!
I have big .txt file which i want to read, process and write to another .txt
file.
I have done script for that, but im having problem with croatian characters
(Š,Đ,Ž,Č,Ć).
How can I read/write from/to file in utf-8 encoding?
I read file with fileinput.input.
thanks

It seems that some TypeError messages have changed between versions
2.5 and 2.6, e.g.:
from math import radians
radians ()
in 2.5, this leads to "radians () takes exactly 1 argument (0 given)"
whereas in 2.6, the message is now: "radians () takes exactly one
argument (0 given)"
I agree that the
format(one_number))
number=1,234,567

mmhh... it comes to me now that the gap must be in function loading time...
I'll check ceval.c
However, isn't there a room for a slight optim here? (in this case, the
dead code is obvious, but it may be hidden by complex loops and
conditions)
Cheers

this is quite raw, but i'd add

if len(sys.argv) == 1:
sys.argv.append('-h')
before I call parser.parse_args()

This one is pretty scary
The difference between `return None` and `return` leads to inconsistency and
is in contradiction with the specs, AFAIK. I'm glad we pointed this out.

Therefore, it's
often better to make a package on PyPI, or, if the code is too short, to submit
your handy chunks on ActiveState. If it deserves a general approbation, it
may be included in Python stdlib.

nd dirty call to xclip -o, although there must be a pure python
implementation which in turn depends on the python framework you play
with (gtk/qt/wx/tk/...).
Short answer is : it depends on your system, and it may be easier and more
portable if you use a graphical toolkit.

hat this combination (dynamic typing

Note that the getter/setter plague is useless and unpythonic. Use
properties instead if you need to control attributes access. There are
decorator idioms to make clean and easy properties, look here:

So, for example, your program might look like this:
base_price = int(raw_input(...))
tax_rate = int(raw_input(...)
tax_amount = base_price * ((100+tax_amount)/...)
s/(100+tax_amount)/(100 + tax_rate)/, I guess ?

the past I've never been able to very good, definitive documentation

The bad news is that dict are *not* ordered, so you'll have to sort the
result yourself if needed :(
The good news is that sorting a sequence is a no-brainer too !-)
