Иногда бывает ситуация когда dev-сервер по какой-либо причине не закрылся и висит в процессах, занимая порт.
Это может быть из-за падения IDE или просто сам забыл погасить и закрыл терминал.
Для таких случаев я набросал простую функцию с командой:
kill_on_port() {
port=$(lsof -t -i:$1)
echo "KILL PROCESS:" $port
sudo kill -9 $port
}
alias killonport="kill_on_port $@"
Код поместить в ~/.bashrc и рестартнуть систему.
Если во время старта dev-сервера получаете ошибку что порт уже занят, просто выполните команду, подставив свой порт.
Bash
kill_on_port 8000
Скорее всего бесполезно, если другой процесс назначен на перезапуск вашего dev-сервера в случае падения.
Имя команды можете изменить на любое другое.

http://www.enlistq.com/10-python-idioms-to-help-you-improve-your-code/
If you have ever tried to learn a new language (not a programming language), you know that we always think in our native language before we translate it to the new language. This can lead to you forming some sentences that don’t make sense in the new language but are perfectly normal in your native language. For example, in a lot of languages, you ‘open’ an electronic gadget such as fan, AC or cell phone. When you say that in English, it means to literally open the gadget instead of turning it on.
The same is true for programming languages. As we pick up new languages, such as #python, we are using our prior knowledge of programming in another language (q, java, c++ etc) and translating that to python. Many times, your code will work but it won’t be ‘#pretty’ or #fast. In python terms, your code won’t be ‘#pythonic’.
