Remove duplicate content in Mapping types - dict documentation

cpython/Doc/library/stdtypes.rst

Lines 4971 to 4990 in 1ae9004

	Providing keyword arguments as in the first example only works for keys that
	are valid Python identifiers. Otherwise, any valid keys can be used.
	Dictionaries compare equal if and only if they have the same ``(key,
	value)`` pairs (regardless of ordering). Order comparisons ('<', '<=', '>=', '>') raise
	:exc:`TypeError`. To illustrate dictionary creation and equality,
	the following examples all return a dictionary equal to
	``{"one": 1, "two": 2, "three": 3}``::
	>>> a = dict(one=1, two=2, three=3)
	>>> b = {'one': 1, 'two': 2, 'three': 3}
	>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
	>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
	>>> e = dict({'three': 3, 'one': 1, 'two': 2})
	>>> f = dict({'one': 1, 'three': 3}, two=2)
	>>> a == b == c == d == e == f
	True

The first two sentences in the snippet above are duplicated under the example.

I think it would be better if the second occurrence were removed?
