kandi X-RAY | PyBox Summary
PyBox works on the basis of reading a file that defines reactions between compounds in the gas phase and the associated reaction coefficient. For example, take the MCM Alpha-Pinene chemical mechanism file 'MCM_APINENE.eqn.txt' stored in the 'mechanism_files' directory of PyBox. This contains the following snippet of text:. Where the equation number is defined first, then the reactants/products along with a defined rate coefficient. This equation file is parsed by functions in 'Parse_eqn_file.py', providing information that can be used to set up and solve the relevant ordinary differential equations (ODEs) to simulate the evolution of the chemical mechanism. Each component in this chemical mechanism also has an associated record of chemical structure in the form of a SMILES string. This information is carried in a .xml file, provided by the MCM, and stored in the root directory of PyBox. Why is this important? Well, this information is taken by the UManSysProp informatics suite and allows us to predict properties of each compound that helps us predict whether they are likely to remain in the gas phase or condense to an existing particulate phase through gas-to-particle partitioning. Before we take a look at the directory structure provided in this repository, lets deal with the dependencies.

QUESTION
What is the proper syntax to import view.py into urls.py
I am trying to add pagination and search and have run into a SyntaxError "SyntaxError: invalid syntax" .
I tried my best to debug it the last few days. I can see it is the way I am importing view. I tried a bunch of combinations and made it worse any guidance extremely appreciated.

I have a C++ class that contains two overloaded methods sayHi(), each with a different return type:
...ANSWER
Answered 2019-May-17 at 16:28You need to return a Python int. In C/C++ source this is a PyLongObject (Which is a subtype of PyObject, so you can cast a PyLongObject* to a PyObject* and back). To convert a C++ int into a PyObject* Python int, use PyObject* PyLong_FromLong(long):

I have created getsetters for a public variable number_bananas I have in my Box class. number_bananas is public because the box is unlocked, anyone can eat bananas or put more in the box.
Here is my PyBox type:
...ANSWER
Answered 2019-May-13 at 16:39self->bx->number_bananas is not a PyObject* so can't be increfed or decrefed. Instead you want to be converting it to/from a PyObject*. In Python3 you do this with various PyLong_* functions.

QUESTION
I have a C++ class Box that I want to wrap up using python C++ api.
The class is defined as:
...ANSWER
Answered 2019-May-09 at 19:12The basic issue is that bx is a pointer, so bx->id could literally anywhere in memory relative to PyBox. Therefore offsetof can never work and thus defining the members in PyMemberDef also can never work.
One solution would be to change the class definition so Box is part of the class (and so an offset is meaningful). This may or may not make sense depending on your C++ code:
