Are there any error messages? If there is not enough information, no one can help you solve the issues. Personal guess: Did you not add python.exe to the Path environment variable?

I just wrote a very short code can fulfill your needs:
a = 2342
b = int("".join(map(lambda x: str((int(x)-3)%10) ,list(str(a)
It does the following things:
1. Convert a number into a string, and then convert this string into
a list of single characters.
2. Write a lamdba expression to apply your conversion rules to a
single-character type number (just subtract 3 and then modulo 10).
3. Apply the lambda expression to the above string list through map.
4. Finally join the modified list into a string and convert it into an
integer.

But in your second example, the generator first traverses all the elements, and then generates an iterable object, you are trying to append this object to s. Let's look at a simpler but more certain example: a = [1, 2, 3] s = [] for n in a: s.append(n) # Result: # len(s) == 3 # s == [1, 2, 3] a = [1, 2, 3] s = [] g = (n for n in a) s.append(g) # Result: # len(s) == 1 # list(s[0]) == [1, 2, 3] If you want to get the same result in the above two cases, just replace append with extend. list.extend() can accept an iterable object as input, and then append all the elements to the original list. -- OpenPGP fingerprint: 3C47 5977 4819 267E DD64 C7E4 6332 5675 A739 C74E signature.asc Description: PGP signature -- https://mail.python.org/mailman/listinfo/python-list
XML parsing ExpatError with xml.dom.minidom at line 1, column 0
Hi,
i've a Python script which stopped working about a month ago. But until then,
it worked flawlessly for months (if not years). A tiny self-contained 7-line
script is provided below.
i ran into an XML parsing problem with xml.dom.minidom and the error message is
included below. The weird thing is if i used an XML validator on the web to
validate against this particular URL directly, it is all good. Moreover, i
saved the page source in Firefox or Chrome then validated against the saved XML
file, it's also all good.
Since the error happened at the very beginning of the input (line 1, column 0)
as indicated below, i was wondering if this is an encoding mismatch. However,
according to the saved page source in FireFox or Chrome, there is the following
at the beginning:
=
#!/usr/bin/env python
import urllib2
from xml.dom.minidom import parseString
fd = urllib2.urlopen('http://api.worldbank.org/countries')
data = fd.read()
fd.close()
dom = parseString(data)

Compilation problem of Python2.5.1 on AIX5.2 (with --enable-shared option)
Dear All, I encountered a problem when compiling Python2.5.1 as shared library on AIX5.2. Your help are greatly appreciated. In order to embed python into our product, we want to compile python as shared library. It works for Solaris and Linux. Unfortunately, It is for AIX and I could not find solution from Web. Could you help answer the following questions: Is it feasible to compile python2.5.1 as shared library for AIX5.2? or where can I find relevant documentation/info for this? So far, the only documents I have are the README and Misc/AIX-NOTES in the source distribution The step I tried to compile python as shared library is to follow README, section "Building a shared libpython", which suggests to add --enable-shared during configuration. My problem is that with --enable-shared, the make step could not complete (the error message shows it tries to refer to "-lpython2.5" in a wrong directory). Then if I refer it to the correct directory (which is compiled in source root), some warning messages show duplicated symbols. And finally I just remove "-lpython2.5", the make could finish but the resulting python interpreter is a statically-linked binary. (The detail is shown below). The detail of my compilation 1. CC="cc_r" ./configure --prefix=/src/new/python2/install --without-gcc --disable-ipv6 --enable-shared 2. make CC="cc_r" OPT="-O -qmaxmem=4000" An error occurred when compiling python extensions. ... running build running build_ext INFO: Can't locate Tcl/Tk libs and/or headers building '_struct' extension creating build ... cc_r -DNDEBUG -O -I. -I/vega5/prod/src/new/python2/Python-2.5.1/./Include -I./In clude -I. -I/usr/local/include -I/vega5/prod/src/new/python2/Python-2.5.1/Includ e -I/vega5/prod/src/new/python2/Python-2.5.1 -c /vega5/prod/src/new/python2/Pyth on-2.5.1/Modules/_struct.c -o build/temp.aix-5.2-2.5/vega5/prod/src/new/python2/ Python-2.5.1/Modules/_struct.o creating build/lib.aix-5.2-2.5 ./Modules/ld_so_aix cc_r -bI:Modules/python.exp build/temp.aix-5.2-2.5/vega5/pro d/src/new/python2/Python-2.5.1/Modules/_struct.o -L/usr/local/lib -lpython2.5 -o build/lib.aix-5.2-2.5/_struct.so ld: 0706-006 Cannot find or open library file: -l python2.5 ld:open(): No such file or directory *** WARNING: renaming "_struct" since importing it failed: No such file or directory error: No such file or directory make: The error code from the last command is 1.

As a result, I filter out all "-lpython2.5" passed to ./Modules/ld_so_aix for the rest commands. In this way, the python interpreter was generated. However, it is a big executable and "ldd python" does not show it depends on any python shared library (It seems no shared python library generated). It has no difference from the one compiled without --enable-shared. Note that if the configuration is run without --enable-shared option, the corresponding commands will not contain "-lpython2.5".

parallel computations: subprocess.Popen(...).communicate()[0] does not work with multiprocessing.Pool
Hi, I am having an issue when making a shell call from within a multiprocessing.Process(). Here is the story: i tried to parallelize the computations in 800-ish Matlab scripts and then save the results to MySQL. The non-parallel/serial version has been running fine for about 2 years. However, in the parallel version via multiprocessing that i'm working on, it appears that the Matlab scripts have never been kicked off and nothing happened with subprocess.Popen. The debug printing below does not show up either. Moreover, even if i replace the Matlab invocation with some trivial "sed" call, still nothing happens. Is it possible that the Python interpreter i'm using (version 2.6 released on Oct. 1, 2008) is too old? Nevertheless, i would like to make sure the basic framework i've now is not blatantly wrong. Below is a skeleton of my Python program: -- import subprocess from multiprocessing import Pool def worker(DBrow,config): # run one Matlab script cmd1 = "/usr/local/bin/matlab ... myMatlab.1.m" subprocess.Popen([cmd1], shell=True, stdout=subprocess.PIPE).communicate()[0] print "this does not get printed" cmd2 = "sed ..." print subprocess.Popen(cmd2, shell=True, stdout=subprocess.PIPE).communicate()[0] print "this does not get printed either" sys.stdout.flush() ### main program below .. # kick off parallel processing pool = Pool() for DBrow in DBrows: pool.apply_async(worker,(DBrow,config)) pool.close() pool.join() .. -- Furthermore, i also tried adding the following: multiprocessing.current_process().curr_proc.daemon = False at the beginning of the "worker" function above but to no avail. Any help would really be appreciated. -- http://mail.python.org/mailman/listinfo/python-list

I discovered a bug in the no-ip dynamic dns free hostname auto renewal/confirmation script written by loblab
Subject: I discovered a bug in the no-ip dynamic dns free hostname auto
renewal/confirmation script written by loblab
Good day from Singapore,
Programming code troubleshooting person: Mr. Turritopsis Dohrnii Teo En
Ming (Targeted Individual)
Country: Singapore
Date: 15 to 16 August 2020 Singapore Time (Saturday and Sunday)
My IT consulting company in Singapore asked me to install a Linux
virtual machine so that we can run no-ip dynamic dns free hostname auto
renewal/confirmation script written by loblab. I am an IT consultant in
Singapore, 42 years old as of 16 Aug 2020.
I am not a Python or Java programmer or software developer. The last
time I had formal training in structured C programming (not C++ objected
oriented programming) was more than 20 years ago at Singapore
Polytechnic (Diploma in Mechatronics Engineering course year 1995-1998).
Although I am not a programmer or software developer, I can still more
or less understand the flow of programming code.
I chose Debian 10.5 64-bit Linux to install as my virtual machine/guest
operating system because loblab mentioned that his scripts have been
tested on Debian 9.x/10.x. But first I have to install VMware
Workstation Pro 15.5.6 in my Ubuntu 18.04.3 LTS Linux desktop operating
system. The iso file I downloaded is debian-10.5.0-amd64-netinst.iso.
The virtual network adapter in my Debian 10.5 Linux virtual machine was
configured to use Network Address Translation (NAT). You can verify the
IP address of your VM with the following Linux commands:
$ ip a
$ ip route
Give your Debian 10.5 Linux VM at least 2 GB of RAM.
After installing Debian 10.5 Linux virtual machine (minimal installation
with SSH server and standard system utilities), I need to do a few more
things, as follows.
# apt install sudo
# usermod -aG sudo teo-en-ming
# groups teo-en-ming
So that I can sudo as a regular Linux user.
# apt install git
Then I downloaded the no-ip ddns free hostname auto renewal/confirmation
script using git clone.
Software: Script to auto renew/confirm noip.com free hosts
Download link: https://github.com/loblab/noip-renew
Programmer: loblab
I believe programmer loblab is based in China.
The version of the scripts I downloaded is 1.1 dated 18 May 2020.
The composition of the software is 58.4% Python programming language,
36% Linux shell scripts, and 5.6% Dockerfile.
I tried to run setup.sh Linux shell script and choose "Install/Repair
Script". But I found out that nothing is being installed in
/usr/local/bin after a few installation attempts.
I thought the scripts/installation were being blocked by AppArmor, so I
went to disable AppArmor using the following Linux commands.
$ sudo mkdir -p /etc/default/grub.d
$ echo 'GRUB_CMDLINE_LINUX_DEFAULT="$GRUB_CMDLINE_LINUX_DEFAULT
apparmor=0"' \
| sudo tee /etc/default/grub.d/apparmor.cfg
$ sudo update-grub
$ sudo reboot
$ aa-enabled
$ sudo aa-status
But AppArmor is NOT the cause of the problem.
I began to examine the Python programming code and Linux shell scripts.
For the setup.sh script, when you choose "Install/Repair Script", it
will call the installer() function. Inside the installer() function, it
will call the following functions, in sequence:
config(), install(), deploy()
When the install() function was called, it tried to execute the
following Linux command:
$SUDO apt -y install chromium-browser # Update Chromium Browser or
script won't work.
Executing the above Linux command resulted in an ERROR because Debian
10.5 Linux does not have the chromium-browser software package. Instead
it has the chromium package.
When the above error is encountered, the installer script ABORTED
PREMATURELY and could not continue running. The installer script could
not run to completion. This is the bug.
To fix the bug, I have to COMMENT OUT/DISABLE the following line in
setup.sh script:
$SUDO apt -y install chromium-browser # Update Chromium Browser or
script won't work.
And add the following line below the above-mentioned line:
$SUDO apt -y install chromium
It fixed the bug. I ran setup.sh script again, choose "Install/Repair
Script", and the installer ran to completion. Finally the scripts are
installed in /usr/local/bin.
Please DO NOT add your no-ip account password to noip-renew.sh script
manually in plain text because it has to be Base64 encoded/encrypted. If
you add your no-ip account password directly to noip-renew.sh script,
you will get an "Incorrect Padding" Python programming base64 error
code.
You need to supply the no-ip account password when you run the installer
script. When the installer script calls the deploy() function, it will
also call the noip() function.
The noip() function is as follows:
function noip() {
echo "Enter your No-IP Account details..."
read -p 'Username: ' uservar
read -sp 'Pass

Noted with thanks. I will contact the script authors.
