Hey Lucena,

Thank you for suggestion, yeah process queues doing the samething, creating new 
sesssion for each process and executing simulatenously.. requirement is served..

but still i want to tackle the situation with locks, but not able to as

0, but there was no child process. Did someone else call waitpid() on our

Hi,

I want to use a code snippet found on-line. It has such content:

from numpy import *

# Initialization of state matrices
X = array([[0.0], [0.0], [0.1], [0.1]])

# Measurement matrices
Y = array([[X[0,0] + abs(randn(1)[0])], [X[1,0] + abs(randn(1)[0])]])



When the above content is inside a .py document and running, there will be
  an error:

---> 15 Y = array([[X[0,0] + abs(randn(1)[0])], [X[1,0] + abs(randn(1)[0])]])
  16 #Y = ([[X[0,0]], [X[1,0] + 0]])

NameError: name 'randn' is not defined


But when I run the above line by line at the console (Canopy), there will be
no error for the above line.

My question is:

The import and the following are wrong.

X = array([[0.0], [0.0], [0.1], [0.1]])

It should be:

import numpy as np
...
Y = np.array([[X[0,0] + abs(np.randn(1)[0])], [X[1,0] + abs(np.randn(1)[0])]])

This looks like the code I once saw. But the file when running has such
  error:

---> 15 Y = np.array([[X[0,0] + abs(np.randn(1)[0])], [X[1,0] + 
abs(np.randn(1)[0])]])

AttributeError: 'module' object has no attribute 'randn'

When it is run line by line at the console, it has the same error.

It is strange that the same content has errors depends on inside a file, or
at CLI console.

What is missing I don't realize? Thanks,




You can try :
from numpy import *
from numpy.random import *

Really? How do you get that answer? What is `a`?

Neither do I, because you have not told us what `a` is.

But I know what `a[0:10:2]` *should* be:

it takes a copy of elements from a, starting at position 0, ending just
before position 10, and taking every second one.


py> a = list(range(100, 121))
py> print(a)
[100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114,
115, 116, 117, 118, 119, 120]

py> print(a[0:10])
[100, 101, 102, 103, 104, 105, 106, 107, 108, 109]

py> print(a[0:10:2])
[100, 102, 104, 106, 108]

py> print(a[0:10:3])
[100, 103, 106, 109]


By default, the first item is automatically 0, so these two slices are the
same:

a[0:10:2]
a[:10:2]


If the start or end position are out of range, the slice will only include
positions that actually exist:

py> a[:1:5]
[100, 105, 110, 115, 120]

Here's another version, but with a deliberate bug in it. You may use
this code if and only if your comprehension is sufficient to detect
and correct that bug.

next(filter(None,(print(next(filter(None,reversed(x for x in
enumerate(itertools.islice(itertools.cycle(("Fizzbuzz",0,"","Fizz",not
"Fuzz","Buzz","Fizz",(),bytes(),"Fizz","Buzz",{},"Fizz",False,globals().get(math.pi))),1,101,None)

Actually... you know what, I think debugging THAT is a malicious prank
to pull on an experienced Python programmer; plus, if you're caught
submitting that for your project, you deserve all the shame you get.
Trust me, this is NOT good code. Here's the corrected version. It
works, but you do not want to use this.

next(filter(None,(print(next(filter(None,reversed(x for x in
itertools.islice(enumerate(itertools.cycle(("Fizzbuzz",0,"","Fizz",not

You are lying to us somehow.  That attempt to print (as you've written 
it) does not produce the the line of output you've indicated.  Instead 
it produces a syntax error, because Python does not use a colon in that

So change your print:(...) lines to print(...) (without the colon) and

WinXP invalid python 3.5 installation

[lokotraktor]

Dear all,

Would you be so kind and help me to find a fix of my trouble?

I have had installed python 2.7 already.
I have downloaded the
https://www.python.org/ftp/python/3.5.0/python-3.5.0.exe
and have installed it on Windows XP Home Edition Version 2002 SP3 (I am the 
administrator, which is on czech laguage the word "Spravce".)

Please see kindly attachements:
python_3,5_empty_installer_window.png
.. First I saw the incomplete python installer window. Clicking just in the 
"empty middle" the installation process of the Python 3.5.0 started and 
succesfully (?)  finished.

Trying to launche the newly installed python I encounter troubles depicted 
at:
python_3,5_not_valid_app_of_win32_type.png .. python.exe is not valid 
application of Win32 type.
python_3,5_not_valid_app_of_win32_type_2.png .. (The "Pristup byl odepren." 
means Acces denied.)

After a little bit googling I have find depends.exe to get know the python 
installation was complete or not.
The finding of depends is not good. See kindly the
python_3,5_depends_s_finding.png

Finaly I tried to uninstall python 3.5. using Control panels, Add or Remove 
Programs, Python, Uninstall (everything on czech language so that I do not 
know propper english wnidows terms). As I see the "incomplete python 
installer window" I tried to click in the middle of empty area. Another fail
appeared to me:
python_3.5_unable_to_remove.png
python-unistal-log.txt

Is something I can fix to obtain fully working upgrade of Python 3.5 on my 
Windows XP?
Please, feel free to ask me for more detailled information.

Correct. `yield` exits the running function, but unlike `return`, the
function doesn't close down, it just pauses, ready to start up again when
you call next() on it.

Here is an example of an ordinary function:

py> def function():
... return 1
... return 2
... return 3
...
py> function()
1
py> function()
1

Each time you call the function, it starts again at the beginning, and exits
after the first `return`. So the lines `return 2` and `return 3` are dead
code that never gets run.

Here is an example of a generator function with yield. Calling generators is
a bit different from calling a function: first you have to initialise them
by calling the function to create a "generator object", then you call the
next() function to advance to the next `yield` statement, and finally they
raise an exception when there are no more `yields`.

An example might help:

py> def generator():
... yield 1
... yield 2
... yield 3
...
py> gen = generator()
py> next(gen)
1
py> next(gen)
2
py> next(gen)
3
py> next(gen)
Traceback (most recent call last):
  File "", line 1, in 
StopIteration


To start the generator from the beginning again, you have to create a new
generator object by calling the function:

gen = generator()


Calling next() many times is often inconvenient. Normally you will iterate
over the generator:

for x in gen:
print(x)

or you call collect all the items using list(). See example below.

Here is a generator which takes a list as argument, and returns a running
sum of the list values:

def running_sum(alist):
total = 0
for value in alist:
total += value
yield total


And here is an example of using it:

py> gen = running_sum(data)
py> list(gen)
[1, 3, 6, 16, 18, 18, 23]

You're not going to be able to install Python 3.5 on Windows XP - the
latest Python doesn't support the old Windows. You can upgrade to
Windows 7 or 8 or 10, or downgrade to Python 3.4, or jump across to
Linux or some other OS. The installer for 3.5 currently isn't very
clear about the problem, but that's going to be changed in a couple of
weeks, so you'll know what your options are.

Heh, I think I got the order of them backwards. You should try to convert to
int first, and if that fails, try float.

Obviously this code assumes you want to distinguish between ints and floats
for some reason. In Python, unlike Lua, Javascript and a few others, we do
distinguish between ints and floats. Since they have different
capabilities, that may sometimes be useful:


py> 10.0 ** 400
Traceback (most recent call last):
  File "", line 1, in 
OverflowError: (34, 'Numerical result out of range')
py> 10 ** 400

Right. If you check int() first and then float(), you can make use of
this. But if the user enters that string and you try to float() it, it
will work:

>>> float(str(int(10**400)))
inf

Hence my confusion. :)

With that small change, your code makes fine sense.

This one recycles fish in a way that looks a bit worrying but it seems
to work. If there's a bug, it's not deliberate. Except stopping at 15 is
deliberate.

from contextlib import contextmanager as fish
from collections import defaultdict as fowl

chip.update(((fowl(int)[fish],fish),))

pexpect matching?

[Didymus]

Greetings,

  I have the following code:

import pexpect

child = pexpect.spawn('/bin/bash')
i = child.expect_exact('bash-3.2$ ')

child.sendline("rpm -q --queryformat '%{VERSION}\\n' glibc")
i = child.expect (['2', '2.5', '2.52.5', pexpect.TIMEOUT])

print  child.before
print '---'
print  child.after

if i == 0:
print 'We got 2'
elif i == 1:
print 'We got 2.5'
elif i == 2:
print ' We got 7'
elif i == 3:
print 'Timed Out!'
else:
print 'What happened?'

The output of the commandline is:

% rpm -q --queryformat '%{VERSION}\n' glibc
2.5
2.5


I've tried to use "\b", "^", "$" around the return stings and even 
expect_exact, but end up with it printing "We got 2". It's just mathcing the 
first character and not the entire string.

rpm -q --queryformat '%{VERSION}\n' glibc

---
2
We got 2

What am I doing wrong here? What do I need to tell the expect line  to grab the 
entire line back to check against?

Thanks

If your friend is writing code for 2.7 and not writing for 2/3
compatibility, then you're not going to be able to run that code in Python
3. A virtual env won't help with that, because it's still Python 3.

Get your friend to upgrade to Python 3, or to write compatible code (there
are tools to help with this), or install Python 2.7.

I don't think there's currently a way to do what you want, but it
seems like a reasonable thing to do.  Would you mind raising an
enhancement request on bugs.python.org?

About the closest you could come currently would be to specify the
full path to the interpreter, but of course that may vary by machine.

write data in Excel using python

[syedmwaliullah]

hi, 
I am trying to write Excel file suing output from another software where the 
output comes as myturnlist.Show()

The first part is for the output from the software which is saved in the 
clipboard. 

The big middle part works to open Excel and save the data into excel file 
called "TurnData.xlsx". 

For some reason it doesn't save the file. 

Any idea?

Thanks in advance.


import VisumPy.excel

# Write to Excel

myturnlist.Show()
turnData = myturnlist.SaveToClipboard(59,0)

excel = win32com.client.Dispatch("Excel.Application")
wb = excel.Workbooks.Add()
exce.Visible = True
wb.WorkSheets[0].Paste()
excel.activeWorkbook.SaveAs ("c:\TurnData.xlsx")

myturnlist.Close()

The first place to look is PyPI. It's here:

You might want to look at the links for the homepage and documentation.
That mentions a later version.

You can also just use a forward slash:

excel.activeWorkbook.SaveAs("c:/TurnData.xlsx")

Windows happily accepts this.

The question asks to get an input from the user and print if it's a
palindrome or not.
It should be just

strA=raw_input()
if strA==strA[::-1]:
print "Palindrome"
else:
print "Not"

Right? Am I missing something? Why are you generating random strings and
trying to check for palindromes?​

The instructions do ask for input.  I am lazy.  I thought it would be
