Hmmm, the power function has basically two definitions:
a ** n
for integer n, pow is defined for all a in R.
for real n, pow is defined only for non-negative a.
If you think how a**x is derived (as a generalization from a**(p/q)),
that makes sense.
Basically, a ** (p/q), p > 0, q > 0, gcd(p, q)

As usual there are a number of ways.
But I basically see two steps here:

The answer is slightly more complex.
1.) objects are either mutable or immutable. E.g. tuples and strings are
per definition immutable and "constant". Lists and dictionaries are an
example of the mutable kind.
2.) "variables", "instance members" are all only references to objects.

What you probably want is:

If you are not sure that the list have at least three elements, you can
use something like this:
[(elem_list + [None, None, None])[2] for elem_list in List]

Well, chmod 0700 is usually not want you want:
a) 0700 gives only read/write/execute rights to the user. Technically
for historical reason permissions can be written as an octal number,
with the first digit being optional, encoding stuff like setuid/s

That's in the nature of the underlying database library used for the

used as hashmap. E.g. compare ls -l versus du of the database file.
Now if this is the case, there is no way (wi

DBAPI is an interface standard describing what you can expect in a

Well he could implement the indexing into his program and check mtimes to
decide if he needs to reindex.
But yes, as long the file fits into memory, readlines (or
list(file("quotes,txt")) makes more sense.

I haven't done anything like that as I don't use Windows for anything serious.

Well, philosophically every object "name" is a pointer to a PyObject on
C level. The only difference is, that you cannot do anything but assign
these pointers (no pointer arithmetic) and memory is managed automatically.

Simple, defining __hash__ on a class allows you to supply a hash value
for instances of your class.

Well, take a look at the socket module and nonblocking mode.

Unqualified names reference always only objects defined in the local

If you want to use unqualified names, you could do something like that:
