Congratulations on a fantastic work!

I can confirm this,
I am getting very slow read performance when reading a smaller 20 MB
file.
- Python 2.5 takes 0.4 seconds
- Python 3.0 takes 62 seconds
fname = "dmel-2R-chromosome-r5.1.fasta"
data = open(fname, 'rt').read()
print ( len(data) )

It's been a while so I can't remember, but it seems like "yield" was
dropped in to python relatively quickly in 2.2. Was there a similar
outrage when "yield" became a keyword?

Turns out write performance is also slow!
The program below takes
3 seconds on python 2.5
17 seconds on python 3.0
yes, 17 seconds! tested many times in various order. I believe the
slowdowns are not constant (3x) but some sort of nonlinear function
(quadratic?) play with the N to see it.
Could someone run the code below on both Python 2.5 and 3.0
For me (on Windows) it runs over 7 times slower with Python 3.0
import time
lo, hi, step = 10**5, 10**6, 10**5
# writes increasingly more lines to a file
for N in range(lo, hi, step):
fp = open('foodata.txt', 'wt')
start = time

I see, thanks for the clarification.
I will make the point though that this makes python 3.0 unsuited for
anyone who has to process data

Does this fix speed up the write() function as well?
A previous poster suggested that in this case the slowdown

Originally, like many others here I said YIKES! but on a second read,
it is not that bad. It actually grows on you.
After looking at it one more time I found it neat, very concise
without being unreadable.

I'm looking at a person's code and I see a lot of stuff like this:
def myfunction():
# do some stuff stuff
my_string = function_that_returns_string()
# do some stuff with my_string
del my_string
# do some other stuff
r
Say I have module foo.py:
def a(x):
def b():
x
del x
If I run foo.py under Python 2.4.4 I get:
File "foo.py", line 4
del x
SyntaxError: can not delete variable 'x' referenced in nested
scope
Under Python
