I installed Python 3.4rc3 on Windows 7, I downgraded pip (from 1.5.3) to 1.5.3
and then I uninstalled Python 3.4rc3. Some files of pip and setuptools remaing
in C:\Python34, is it expected?
C:\Python34\Scripts:
easy_install-3.4.exe
easy_install.exe
pip.exe

New submission from STINNER Victor:
According to tracemalloc, import base64 allocates 920.6 kB of memory. The 3
top locations are:
Lib/base64.py:414: size=420 KiB, count=7226, average=59 B
_b85chars2 = [(a + b) for a in _b85chars for b in _b85chars]
Lib/base64.py:306: size=420 KiB,
New submission from Mark Lawrence:
The upgrade from 3.3.4 to 3.3.5 has removed py[w].exe from c:\windows. Tim
Golden has given a possible explanation here

I don't think Tim's theory is true, but I can't suggest a better explanation.
This would need to be debugged, by running
msiexec /i name-of-installer.msi /l*v python.log
and submitting the resulting python.log here.

This is indeed expected, and applies to any other packages you have installed
from PyPI as well (and also to any files that you manually created in the
installation directory). Python only removes what it installed itself.

It's a classical time-space trade-off. I'm not sure this is a bug; if it is,
the reasonable change (IMO) is to just revert the introduction of these *2
tables, and loop through the output character-by-character.
I'd personally be in favor of such a change
Martin v. Löwis added the comment:
I'm also -0 on delayed creation of the tables. If these encodings are used, the
memory overhead will still occur.

I'd personally be in favor of such a change (drop the tables).
I didn't propose to drop the table, but create a table the first time that it
is needed.
I never used ascii85 nor base85 nor base32 in my applications. Maybe because
ascii85 and base85 are new

base64_on_demand.patch: create tables the first time they are needed.
b85decode() already uses such trick to build _b85dec.
Note: a85decode() doesn't use a precomputed table.
If people think that these functions are too slow, they should propose an
