Would you mind give me some list compression examples?
Thanks & really appreciate that.

it looked simpler when i posted, but i realize that the problem is non
trivial.
thanks to everybody.
i guess that the algorithm would be easier if it was known in advance
that the string to substitute must have some specific property, say:
1) they all must start with "XYZ"
2) they all have t
hi.
what is the most pythonic way to substitute substrings?
eg: i want to apply:
foo --> bar
baz --> quux
quuux --> foo
so that:
fooxxxbazyyyquuux --> barxxxquuxyyyfoo

what's the difference between:

if input_line:
sys.stdout.write(input_line.upper())

Any language that gets any sort of real use has to have. For instance,

That's an interesting point, but not relevant at the end of the day:
`foo.length` and `length(foo)` have the same "practicality". On the
other hand Ruby can be praised for the coherence: everything's a method

hi clp.
i want to get from here:
nomi = ["one", "two", "three"]
to here:
0 - one
1 - two
2 - three
i found two ways:
first way:
for i in range(len(nomi)):
print i, "-", nomi[i]
or second way:

which one is "better"? is there a more py

You have the string wrong.
oops yea.
But the correct one you get with:
In [67]: import struct
In [68]: number = 252509952
In [69]: struct.pack('>I', number)
Out[69]: '\x0f\x0c\xff\x00'
(Please note that this is big endian)
thanks a lot, but it does not work f
