Бывает начинающие в процессе обучения создают файлы с именем модуля который они изучают. В результате на тестовых запусках ничего не работает😱 Всё потому, что появилась коллизия имён. Например, изучаете вы модуль datetime, и создаёте с таким именем файл (ну логично же😄) прямо в рабочей директории. Потом, при попытке импортировать datetime модуль, из-за приоритета импорта будет импортирован файл из рабочий директории а не оригинальная библиотека. Ведь имя файла это суть имя модуля! А знаете ли вы, что не все стандартные модули можно так перезаписать? Коллизии имён не подвержены builtin модули. Они всегда стоят на первом месте в приоритете импорта, поэтому их нельзя заменить. Полный список таких модулей можно посмотреть в списке sys.builtin_module_names. То есть, вы сломаете весь Python если назовёте свой модуль os или site, но если назовёте time или gc то ничего страшного не случится))) Тем не менее, никогда не называйте модули уже занятыми именами!!!⚠️ Я всегда рекомендую всем своим файлам делать именной префикс из 2-3 символов. Например я называю свои проекты так: pw_project_name pw_ui_tools.py pw_something/main.py Либо под ситуацию tst_scriptname.py (не "test" чтобы не подхватывал pytest) dbg_script.py maya_ui.py hou_menu_tools.py И искать проще, и коллизий нет. #tricks#basic

When paying respects this Qing Ming, let’s continue to be socially responsible and observe #SafeDistancing measures. As crowds are expected at Choa Chu Kang Cemetery and government-managed columbaria, visitors are advised to send 2 representatives per household (with not more than 8 pax per group). The opening hours will be extended to 24-hours, with effect from 20 Mar until 18 Apr 2021. Visitors driving to Mandai Columbarium during peak days will also be required to book an appointment. Visit www.nea.gov.sg/qingming2021 for more information.

During Phase 2, you may leave your home to smoke, but do so in an area where smoking is not prohibited, and observe #SafeDistancing requirements. To protect yourself and others around you, do put your mask back on as soon as you have finished smoking. From 19 Jun, Designated Smoking Areas along the Orchard Road No Smoking Zone can re-open with safe distancing measures. Smoking corners beyond the Orchard Road No Smoking Zone, can also re-open with the necessary safe distancing measures in place. www.nea.gov.sg/post-circuit-breaker-measures

Dine-in at #OurHawkerCentres resumes from 19 Jun! Whilst you may be excited to meet with your friends, limit the group to 5 people or less and continue to observe #SafeDistancing measures – use unmarked seats/tables, keep 1 metre apart from others, and only remove your masks when eating. At our markets, continue to stand within the boxes marked on the floor, to maintain a safe distance. Access to the 4 popular markets will continue to be restricted based on the last digit of your identification number.

Need your essentials? In addition to wearing a mask to buy essentials at the supermarket, schedule your grocery run on a weekday and avoid the peak periods, or opt for delivery instead. Let’s take #SafeDistancing seriously, and work together to stop the spread of COVID-19. #SGUnited

Planning dinner with your friends? Due to #SafeDistancing, there may be limited seating capacity at many places, so call in advance to make reservations first. Otherwise, opt for takeaway (bring your own containers!) or delivery 😊#SGUnited#FightCOVID19

#SafeDistancing applies everywhere – even when choosing fish and vegetables at the markets! If you have elderly neighbours or family members, help them with their marketing instead so that they can #StayHome and stay safe. #SGUnited

Let’s remember to stay at least a metre apart from each other. We wouldn’t want all the effort and resources of the past few months to go to waste. Dining in at #OurHawkerCentres? Let’s not forget to #ReturnOurTrays and #BinOurTissues after enjoying the meal! #SGUnited#SafeDistancing#FightCOVID19
