New submission from Kirk McDonald:
The following code gives an unexpected result:
>>> a, b = lambda: 1, lambda: 1.0
>>> a()
1
>>> b()
1
>>> type(b())
>>> a.__code__ is b.__code__
True
The cause boils down to this line of code:

According to PEP 7, older C source files are indented with tabs, and
newer ones are indented with spaces. The vimrc file in the repository
assumes that existing C source files should be indented with tabs, and it

New submission from Kirk McDonald:
One question which is asked with surprising frequency in #python is how
to yield multiple objects at a time from an iterable object. That is,
given [1, 2, 3, 4, 5, 6], get [(1, 2), (3, 4), (5, 6)].
The grouper function in the itertools recipes page provides
) integers. Python may re-use certain small integers when
you might not expect it to; this is done in the interests of efficiency.
If you only compare the /values/ of numbers (with ==), then you will
never notice this.
a = 1
b = 1
c = 100
d = 100
a is b
True
c is d
False

Thanks, Kirk.
I considered the += as only a shorthand notation for the assignment
operator.
Since for lists + is simply a concatetation, I am not sure it x=x+[2]
is creating a brand
new list. Could you refer me to any documentation on this?
Thanks,

My
Python frees it.
The augmented assignment, as I went over previously, attempts to modify
the list object directly. Any names bound to the object (or any other
objects that reference the object) will see the changes.

I do the following. First create lists x,y,z. Then add an element to x
using the augumented assignment operator. This causes all the other
lists to be changed also.
But if I use the assignment x=x+[4] instead of using the augumented
assignment, the y and z lists do not change.

To sort its elements, you need to build a list of the items and sort
that, e.g.:
items = [(v, k) for k, v in self.histo.items()]
items.sort()
This will give you a list of (value, key) tuples sorted by value.
