AppPkg/Applications/Python: Add Python 2.7.2 sources since the release of Python 2.7.3 made them unavailable from the python.org web site.
These files are a subset of the python-2.7.2.tgz distribution from python.org. Changed files from PyMod-2.7.2 have been copied into the corresponding directories of this tree, replacing the original files in the distribution.

+Instead of
+

+
+use
+
+ import anydbm
+ d = anydbm.open(file, 'w')
+
+The returned object is a dbhash, gdbm, dbm or dumbdbm object,
+dependent on the type of database being opened (determined by whichdb
+module) in the case of an existing dbm. If the dbm does not exist and
+the create or new flag ('c' or 'n') was specified, the dbm type will
+be determined by the availability of the modules (tested in the above
+order).
+
+It has the following interface (key and data are strings):
+
+ d[key] = data # store data at key (may override data at
+ # existing key)
+ data = d[key] # retrieve data at key (raise KeyError if no
+ # such key)
+ del d[key] # delete data stored at key (raises KeyError
+ # if no such key)
+ flag = key in d # true if the key exists
+ list = d.keys() # return a list of all existing keys (slow!)
+
+Future versions may change the order in which implementations are
+tested for existence, and add interfaces to other dbm-like
+implementations.
