I have a string of this form
s='arbit'
string='%s hello world %s hello world %s' %(s,s,s)
All the %s in string have the same value (i.e. s). Is there a better way of writing this? (Rather than listing out s three times)

Nice. Had forgotten about this. locals() will do as well.

@Goutham: Adam Rosenfield's answer might be better if you're Python version is up to date.

It is actually. Iam still getting used to the new string formatting operations.

even better, you can multuply the base string: '%(s)s hello world '*3 % {'s': 'asdad'}

A:
You can use advanced string formatting, available in Python 2.6 and Python 3.x:
s='arbit'
string='{0} hello world {0} hello world {0}'.format(s)

Hello,
You can use the dictionary type of formatting:
s='arbit'
string='%(key)s hello world %(key)s hello world %(key)s' % {'key': s,}

Seems to be very little point in providing this duplicate answer. Here's another one: '%(string_goes_here)s hello world %(string_goes_here)s hello world %(string_goes_here)s' % {'string_goes_here': s,}. There's practically an infinite number of possibilities.

A:
Depends on what you mean by better. This works if your goal is removal of redundancy.
s='foo'
string='%s bar baz %s bar baz %s bar baz' % (3*(s,))
