Does Jython have a ternary operator?
I was unable to find it in the guide.
edit: I am using weblogic's jython 2.2.1
The a if condition else b syntax was added to the language in version 2.5. It is available in both CPython and Jython.
Jython 2.2.1 is too old and does not support this syntax.

When I configure odoo with pycharm, I face the following issue:
My personal experience - python 3.8 doesn't fully compatible with Odoo. So I changed it with lower version and works great.
You can try with python 3.7 or 3.6 version.
I've written a program on the python version 3.5.2, because i need a 64 bit version of python for my tensorflow-gpu library.
Its also possible to use the normal tensorflow library, which doese'nt require a 64 bit python, but in my case i wanted to use my gpu.
My question is: If some users have a higher version installed (of python) and use the normal tensorflow library, will they still be able to execute it?

It all depends on what code you used, and if the syntax was changed in later versions. For example, if your version of Python uses print "Hello World!" and the user's version is print("Hello World"), then you would have to change it to the later versions specification.

Thanks in advance,

Have you tried to SOAtest with additional argument?
soatest.exe -Zjava_home "C:/Program Files/Java/jdk1.8/"
I am on a Windows machine and trying to compile the QGLViewer with Qt 5.3. Therefore I use the GQLViewer.pro file to compile the lib with the Qt Creator. Unfortunately it always prompts:
\libQGLViewer-2.5.2\QGLViewer\saveSnapshot.cpp:545: Error: operands to ?: have different types 'QFileDialog::Option' and 'QFlag' overwrite?QFileDialog::DontConfirmOverwrite:QFlag(0));
Anyone an idea how to solve this problem?
This is an error in the QGLViewer library.
Upgrading to a version >= 2.53 should fix it.
2.53 changelog:
Fix QFlag error with recent compilers in saveSnapshot.cpp (thanks xiaoyi).
Python - what is difference in os.popen and subprocess.Popen?
The os process functionality is considered obsolete. The subprocess module was introduced in Python 2.4 as a unified, more powerful replacement for several older modules and functions related to subprocesses. They are listed here:
os.system
os.spawn*
os.popen*
popen2.*
commands.*
os.popen was deprecated in Python 2.6 (but, interestingly, it is not deprecated in Python 3, where it is implemented in terms of subprocess.Popen). There is a paragraph in the documentation on how to replace it with subprocess.Popen.
