Is there a way to just take a slice of the string argument with format()?

With C like formatting we can put just a slice of the string argument within the string. For example, this:

print "I just love %.4s." %('cats and dogs')

will print this:

I just love cats.

Is there an equivalent way to do this using format() ?

You can use: 

print("I just love {:.4}".format('cats and dogs'))

https://pyformat.info/ - this site is an excellent resource to compare how to use format with "old style" format.

In most cases %-based formatting translates into {}-based formatting by adding a colon.

print "I just love %.4s." %('cats and dogs')

is equivalent to:

print "I just love {:.4s}.".format('cats and dogs')

You may omit the s in brackets, like this:

print "I just love {:.4}.".format('cats and dogs')

>>> print "I just love {:.4}.".format('cats and dogs')

Sure, you can use basically the same format:

>>> print('I just love {0:.4}.'.format('cats and dogs'))
I just love cats.
