Subject: n00b= question on spacing

Hi, I have a qu= estion about breaking up really long lines of code in Python.

I have= the following line of code:
log.msg("Item wrote to MongoDB database %s/= %s" %(settings['MONGODB_DB'], settings['MONGODB_COLLECTION']), level=3Dlog.= DEBUG, spider=3Dspider)

Given the fact that it goes off very far to the right on my scree= n is not terribly
pleasing to my eyes (and can be rude for other develo= pers).

I was thinking of splitting it up like so:
log.msg("= Item wrote to MongoDB database %s/%s"
  %(settings['MONGODB_DB'], settings['MONGODB_COLLECTION']),
 = level=3Dlog.DEBUG, spider=3Dspider)

Is this ok?  Are the= re any rules in Python when it comes to breaking up long lines of
code?=

Hi Yves:
PEP8 is your definitive guide for style questions:
&= nbsp; <http://www.python.org/dev/peps/pep-0008/>

and this is a= n interesting set of notes:
  <http://stackoverflow.com/question= s/5931297/how-would-you-properly-break-this-line-to-match-pep8-rules>

Basic rule is to break within parenthesis -- after that it becomes= a matter of personal taste/style.

In your specific example, I would= do something like:
log.msg(
    "Item wrote to MongoD= B database %s %s" % (
settings= ['MONGODB_DB'],
settings['MONGODB_COLLECTION]),
level=3Dl= og.DEBUG,
spider=3Dspider)

Though you might want to:
a) st= art your string right after the log.msg(
b) put more than one settings o= n the same line
c) put the last two parameters on the same line.

= I find that once I start breaking up lines for length, that I prefer to bre= ak up everything.

Also remember when entering long lines of text th= at strings concatenate within parenthesis.
So,
("a, b, c"
"d, e,= f"
"g, h, i")

Is the same as ("a, b, cd, e, fg, h, i")
