How can I split an expression onto multiple lines in Python

Question

How can I split an assignment like this onto two lines?

myLongVariableName = 'some somewhat long format string like this %s' % myOtherVariable

I tried a few variations:

myLongVariableName = 'some somewhat long format string like this %s' 
  % myOtherVariable

myLongVariableName = 'some somewhat long format string like this %s' %
  myOtherVariable

myLongVariableName = 
'some somewhat long format string like this %s' % myOtherVariable

My searching is coming up short. What I've found mostly talks about indenting blocks of code or parameters, not long expressions.

I just found that I can use a backslash at the end of the line. Is there another way? I consider lines ending with backslashes poor style. — Matt Deeds

Adjacent string literals are automatically concatenated in Python:

myLongVariableName = ('some somewhat long format'
                      'string like this %s') % myOtherVariable

This is an option:

myLongVariableName = 'some somewhat long format string like this {}'
    .format(myOtherVariable)
