 Introduction

+This PEP describes a proposed syntactical extension to Python, list
+comprehensions.
 
 
 The Proposed Solution
+=====================
 
-    It is proposed to allow conditional construction of list literals
-    using for and if clauses.  They would nest in the same way for
-    loops and if statements nest now.

 Rationale
+=========
 
-    List comprehensions provide a more concise way to create lists in
-    situations where map() and filter() and/or nested loops would
-    currently be used.

 Examples
+========
+
+::
 
     >>> print [i for i in range(10)]
     [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
 
     >>> print [i for i in range(20) if i%2 == 0]
     [0, 2, 4, 6, 8, 10, 12, 14, 16, 18]
 
-    >>> nums = [1,2,3,4]
+    >>> nums = [1, 2, 3, 4]
     >>> fruit = ["Apples", "Peaches", "Pears", "Bananas"]
-    >>> print [(i,f) for i in nums for f in fruit]
+    >>> print [(i, f) for i in nums for f in fruit]
     [(1, 'Apples'), (1, 'Peaches'), (1, 'Pears'), (1, 'Bananas'),
      (2, 'Apples'), (2, 'Peaches'), (2, 'Pears'), (2, 'Bananas'),
      (3, 'Apples'), (3, 'Peaches'), (3, 'Pears'), (3, 'Bananas'),
      (4, 'Apples'), (4, 'Peaches'), (4, 'Pears'), (4, 'Bananas')]
-    >>> print [(i,f) for i in nums for f in fruit if f[0] == "P"]
+    >>> print [(i, f) for i in nums for f in fruit if f[0] == "P"]
     [(1, 'Peaches'), (1, 'Pears'),
      (2, 'Peaches'), (2, 'Pears'),
      (3, 'Peaches'), (3, 'Pears'),
      (4, 'Peaches'), (4, 'Pears')]
-    >>> print [(i,f) for i in nums for f in fruit if f[0] == "P" if i%2 == 1]
+    >>> print [(i, f) for i in nums for f in fruit if f[0] == "P" if i%2 == 1]
     [(1, 'Peaches'), (1, 'Pears'), (3, 'Peaches'), (3, 'Pears')]
-    >>> print [i for i in zip(nums,fruit) if i[0]%2==0]
+    >>> print [i for i in zip(nums, fruit) if i[0]%2==0]
     [(2, 'Peaches'), (4, 'Bananas')]
 
 
 Reference Implementation
+========================
 
-    List comprehensions become part of the Python language with
-    release 2.0, documented in [1].

 BDFL Pronouncements
+===================
+* The syntax proposed above is the Right One.
 
-    - The syntax proposed above is the Right One.
-
-    - The form [x, y for ...] is disallowed; one is required to write
-      [(x, y) for ...].
+* The form ``[x, y for ...]`` is disallowed; one is required to write
+  ``[(x, y) for ...]``.
 
-    - The form [... for x... for y...] nests, with the last index
-      varying fastest, just like nested for loops.
