I'm working on an NLP and I got bitten by an unreasonably slow behaviour in
Python while operating with small amounts of numbers.
I have the following code:
```python
import random, time
from functools import reduce
def trainPerceptron(perceptron, data):
learningRate = 0.002
weights = perce
? Perhaps relatedly, I noticed that even
in 3.6, the code
print(re.findall(".*","pattern"))
yields ['pattern',''] which is not what I was expecting.
Thanks,

through the text. The get-method has a keyword
argument for creating default values, which might be useful here.
Another thing worth of mentioning is, that python has exactly this kind
of machinery already built-in (collections.Counter), but you should try
and implement a simple version of it yourself as exercise.

the program runs in 0.68 sec instead of 0.79, so there is some shortcut.

This solution is not so good if you have to impose a hard limit on the

First, you should consider reading the documentation of

As a scientist I would be more than happy to publish in Open-Access Journals
rather than in IEEE/ACM/Springer-published ones. However, I also have to be
sure that my publications reach the scientific community and make an impact on
it. Unfortunately, in many fields AFAIK the better journals (= h

That's surprising, because even after changing 5 to 4 both objects still
have different id()s (tested on Py2.7), so 5 is 4 /should/ still be
False (But isn't on my 2.7). But that

Don't know why there is no format character %a or %A in python, but the

While this accidently works in this case, let me remind you that

I am not sure I understand your argument. The doc section states that
" [...] in Python you’re forced to write this:
while True:
line = f.readline()

That simply isn't true as one can simply write:
for line in f:
#do s
e this:
