QUESTION
I have a dictionary of country names, for each country I have stored a numerical value and a tag. the numerical value is a simple frequency I pass to the pygal Worldmap and the tag is a string I want to add to the tooltip.
For example suppose country 'af' and 'cn' have corresponding numerical values 20 and 10, and tags 'AA' and 'BB'. Then the below code works just fine.
...ANSWER
Answered 2021-May-12 at 01:41The variable i is changing. You do not call formatter function until later, at which point i already points to the last element of the for loop. If you could call the formatter straight after it finishes the first element and before it continues to the second, you would get AA.
What you need to do is bind i['tag'] to a parameter of the lambda - tag=i["tag"] so that the value itself will be saved.

I'm working with pygal and I want to embed a pygal chart in a flask app.
However, I want to put a top-bar on the flask app. I don't get any errors, but only the top bar is shown. Nothing else is shown. The pygal chart does not even render.
Here's my code for your reference:
...ANSWER
Answered 2020-Dec-25 at 00:00See the Output section of the docs.
The render_response method returns a response object which is designed to be returned directly from a Flask route, not manually added to a template as per your code. To stick with your own approach, you could do this with the render_data_uri method. For example, by changing the end of your __main__ function to instead:

Answered 2020-Dec-14 at 04:20It appears that the python interpreter is compiled into the mod_wsgi.so file. An old version, that included python2, was being pointed to by Apache. To fix it I did the following:
- Removed the old version of mod_wsgi by doing
sudo apt-get remove libapache2-mod-wsgi - modified /etc/apache2/mods-available/mod_wsgi.load to point to the library (.so) file in my virtual environment. The contents of mod_wsgi looked like this:

QUESTION
I am trying to run tox package on my project which worked fine so far.
I am running in Phycharm on Windows 10 Pro 64-bit, tox version 3.15.0
when I run the command:
python -m tox --recreate
tox tests pass for python3.6,3.7,3.8 but not for Python3.5.
This is the error I get when I run:
python -m tox -epy35
ANSWER
Answered 2020-Oct-06 at 13:12Your reported problem is actual a problem in Python 3.5.0!!
You can check your Python 3.5 version by entering a command like python3.5 --version or just enter python3.5 and have a look at the top of the repl output.
You can resolve the problem by installing the any higher point release of Python 3.5, e.g 3.5.1 or the even the latest one, 3.5.10.
This all said - Python 3.5 is already end of life ( https://www.python.org/downloads/ ). If there is no important reason, please consider to drop support for it.

QUESTION
I'm working on a Rally reporting tool for my team in Python, and I'm trying to package it using cx-freeze. I'm getting a ModuleNotFound error, and I'm wondering if it's because pygal isn't supported by cx-freeze (really hoping this isn't the case because I'd have to rewrite a lot of things)
...ANSWER
Answered 2020-Jul-08 at 07:18cx_freeze does not include all the packages automatically. When you find ModuleNotFoundError, you need to inlcude the module explicitly in your setup like -
build_exe_options = {'packages': ['_sysconfigdata_m_darwin_darwin']}

Install pygal
You can use pygal like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
