pythondev | help | I’ve got a python package that compiles code with Extensions. The C++ extensions depend on other libraries.
* Do I package the dependencies in my whl file?
* How do I accommodate for different operating systems, i.e. macOS / Linux?
This is finally deployed to our pypi server. | 2019-05-31T09:23:35.193100 | Nisha | pythondev_help_Nisha_2019-05-31T09:23:35.193100 | 1,559,294,615.1931 | 26,028 |

pythondev | help | <@Nisha> It really depends. If your package will be used by a very tiny amout of configurations, like one known Linux distro/macos/windows then it's probably worth prebuilding and vendoring. If you don't know exact userbase and their target OSes then I think you have to provide a facility of building extensions upon installation | 2019-05-31T09:39:21.194800 | Nigel | pythondev_help_Nigel_2019-05-31T09:39:21.194800 | 1,559,295,561.1948 | 26,030 |
pythondev | help | And it also depends on whether target OS will have compiler on it | 2019-05-31T09:40:12.195300 | Nigel | pythondev_help_Nigel_2019-05-31T09:40:12.195300 | 1,559,295,612.1953 | 26,031 |
pythondev | help | <@Nigel> very interesting! Upon installation would actually be our best bet here, as the dependencies are handled by `conan`. If you’ve got any links handy to share, I’d greatly appreciate it. | 2019-05-31T09:41:30.196500 | Nisha | pythondev_help_Nisha_2019-05-31T09:41:30.196500 | 1,559,295,690.1965 | 26,032 |

pythondev | help | I think that the best way of learning is by observing how big folks doing this :slightly_smiling_face:
For example, that's how postgresql driver compiles its extension upon installation: <https://github.com/psycopg/psycopg2/blob/master/setup.py#L213> | 2019-05-31T09:43:26.198400 | Nigel | pythondev_help_Nigel_2019-05-31T09:43:26.198400 | 1,559,295,806.1984 | 26,034 |

pythondev | help | <@Nigel> in the case of upon installation extension building, that means that you’d have to install it on the server to test the build? | 2019-05-31T09:51:45.201500 | Nisha | pythondev_help_Nisha_2019-05-31T09:51:45.201500 | 1,559,296,305.2015 | 26,037 |

pythondev | help | Hi, I have been working in a python3.5 virtualenv and when I went to use zappa to deploy my django app to AWS, I learned that zappa doesnt support python3.5. I installed 3.7 and created a new virtualenv but I was wondering if there is an easy way to upgrade a 3.5 virtualenv to 3.7 or migrate the packages versus installing everything from scratch. Is this possible? | 2019-05-31T12:06:34.238000 | Kit | pythondev_help_Kit_2019-05-31T12:06:34.238000 | 1,559,304,394.238 | 26,103 |

pythondev | help | I didnt have a requirements file really as I started by following a few tutorials I’ll have to dig around and figure out what I installed versus django because there are a ton of packages installed in the 3.5 env.

pythondev | help | also, as I was learning how to create the venv in 3.7 I found two ways to write the syntax that create different results and I was wondering which one was correct or preferred.

pythondev | help | Can someone help explain how Python imports work? I’m having a cerebral meltdown over here… read the official docs, spent a day on StackOverflow, but I got nothing but `ModuleNotFoundError` errors as I’m trying to organize a project into multiple files across multiple sub-directories.
For example, when you see something like `from accounts.views import accounts_app`, how do you know if it is:
- A. You are importing a file (i.e. module) `accounts_app.py` from the `accounts/views/` directory?
- B. You are importing a function named `accounts_app` from a `accounts/views.py` file?
- C. You are importing a variable named `accounts_app` from a `accounts/views.py` file? | 2019-05-31T12:23:08.245500 | Nicky | pythondev_help_Nicky_2019-05-31T12:23:08.245500 | 1,559,305,388.2455 | 26,108 |

pythondev | help | Regarding your question: there’s no definitive way to know beforehand.
But usually you can guess depending on the name. Like in `from something import models`, `models` will most likely be a module.
`from something import parse_stuff` - `parse_stuff` is likely a callable. And so on. | 2019-05-31T12:33:05.252300 | Chester | pythondev_help_Chester_2019-05-31T12:33:05.252300 | 1,559,305,985.2523 | 26,116 |
