Hi, I have a question 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=log.DEBUG, spider=spider)
Given the fact that it goes off very far to the right on my screen is
not terribly
pleasing to my eyes (and can be rude for other developers).
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=log.DEBUG, spider=spider)
Is this ok? Are there any rules in Python when it comes to breaking
up long lines of
code?
This is how I'd do it: (And it's *FAR* clearer -- You win no points for
clarity by having it all in one statement.)
fmt = "Item wrote to MongoDB database %s/%s"
msg = fmt % (settings['MONGODB_DB'],
settings['MONGODB_COLLECTION'])
log.msg(msg, level=log.DEBUG, spider=spider)
