Thanks for your reply. btw: I do know what a virtual environment is and how its works. No need to explain. And again: I do expect "pipx" to use virtual environments. So this thread is not about pro and cons of using virtual environments. On 2023-09-17 11:57 Rimu Atkinson via Python-list wrote: >

PEP668 / pipx and "--editable" installs

Hello, I wonder that today was the first day I stumbled over PEP668 / pipx and the "externally-managed-environment" problem. I migrated from Debian 11 to 12. I'm developing some Python packages; applications and libraries. I never used virtual environments and wouldn't like to start with it.

Re: Using "textwrap" package for unwrappable languages (Japanese)

Dear Peter, thanks for your reply. That is a very interesting topic. I was a bit wrong. I realized that textwrap.wrap() do insert linebreaks when "words" are to long. So even a string without any blank space well get wrapped. Am 30.08.2023 14:07 schrieb Peter J. Holzer via Python-list: anot

Using "textwrap" package for unwrappable languages (Japanese)

Hi, I do use "textwrap" package to wrap longer texts passages. Works well with English. But the source string used is translated via gettext before it is wrapped. Using languages like Japanese or Chinese would IMHO result in unwrapped text. Japanese rules do allow to break a line nearly wher
