 Assume you use a for loop to define a few different lambdas (or even plain
 functions), e.g.::
 
-   squares = []
-   for x in range(5):
-      squares.append(lambda: x**2)
+   >>> squares = []
+   >>> for x in range(5):
+   ...    squares.append(lambda: x**2)
 
 This gives you a list that contains 5 lambdas that calculate ``x**2``.  You
 might expect that, when called, they would return, respectively, ``0``, ``1``,

 In order to avoid this, you need to save the values in variables local to the
 lambdas, so that they don't rely on the value of the global ``x``::

-      squares.append(lambda n=x: n**2)

 Here, ``n=x`` creates a new variable ``n`` local to the lambda and computed
 when the lambda is defined so that it has the same value that ``x`` had at
