#7091 — new string formatting with local variables

Hi,

I'd like to simplify the following string formatting:

solo = 'Han Solo'
jabba = 'Jabba the Hutt'
print "{solo} was captured by {jabba}".format(solo=solo, jabba=jabba)
# Han Solo was captured by Jabba the Hutt

What I don't like here is this: "solo=solo, jabba=jabba", i.e. the
same thing is repeated. In "solo=solo", the left part is a key and the
right part is the value of a local variable, but it looks strange.

I'd like something like this:
print "{solo} was captured by {jabba}".format(locals())        # WRONG!

But it doesn't work.

Do you have any idea?

Thanks,

Laszlo

How about:-

print "%s was captured by %s" % (solo, jabba)

Or even

print "{} was captured by {}".format(solo, jabba)

or how about

print "{victim} was captured by {captor}".format(
         victim=solo, captor=jabba)

or maybe

print "{hapless_twit} was captured by {mega_bad_dude}".format(
         hapless_twit=solo, mega_bad_dude=jabba)

Is this Python2.7 specific?

Python 2.6.x : 
>>>print "{} was captured by {}".format('t1', 't2')
ValueError: zero length field name in format

Apparently it is 2.7 and greater -- my apologies for not specifying that.
