splitting a long token across lines
 

Hi all,

Say, I have a very long integer constant , how can
I split across lines ?
I tried something like
MODULUS = 7567567567567567567567567567567\
7567507546546986094860986094860\
2345646986598695869548498698989\
...
but it doesn't compile.
Is there another way to write a long numeric constant besides writing
it as a string and then converting to long? I also wouldn't like to put
it all on one very long line.

Thanks!

Seems that you cannot use line continuation for integers. Unfortunate.

However, using strings to store the value, then later converting it
doesn't incur a significant overhead, as long as you are only
initializing MODULUS once.

MODULUS = '7567567567567567567567567567567'\
'7567507546546986094860986094860'\
'2345646986598695869548498698989'\
...

MODULUS = int(MODULUS)

why can't you just write it like this:

MODULUS = A*pow(10,a) + \
B*pow(10,b) + \
C

Well, I _suppose_ you could do this:


MODULUS = "7567567567567567567567567567567"\
7567507546546986094860986094860"\
2345646986598695869548498698989"\
...

MODULUS = int(MODULUS)

I'm sure I'm going to have to take some flak for this, though. I
wouldn't do it. What's wrong with really long lines? Anything you do
that I can see is going to obscure your code.

Oops, I forgot some quotation marks there, but you get the idea.
