Те, кто в Python не первый день, хорошо знают, что на число можно умножить не только число, но и другие типы. Главное, чтобы у этих типов была реализация такой операции. # list >>> [1] * 3 [1, 1, 1] # tuple >>> (2, 3) * 3 (2, 3, 2, 3, 2, 3) # string >>> "A" * 3 "AAA" Так работает полиморфизм стандартных типов. Интересно здесь то, что это сработает и в том случае, когда порядок операндов обратный. То есть int умножить на [тип]. # list >>> 3 * [1] [1, 1, 1] # tuple >>> 3 * (2, 3) (2, 3, 2, 3, 2, 3) # string >>> 3 * "A" "AAA" Если хотите реализовать такое поведение в ваших классах то следует помнить два момента: 1. Если множитель справа, то вам нужно реализовать метод __mul__, наш класс это первый операнд, то есть слева. myType * 3 2. Если множитель слева, то вам нужно реализовать метод __rmul__, наш класс это второй операнд, справа. 3* myType Всё тоже самое можно делать и для других математических операторов. И если в этом примере действие и результат будут фактически одинаковыми, то бывают ситуации, когда это не так. Например, при умножении матриц имеет значение порядок операндов. Для других операторов, таких как деление или сдвиг, очень важно кто с какой стороны находится. >>> 2/4, 4/2 (0.5, 2.0) >>> 2<<3, 3<<2 (16, 12) >>> 100%15, 15%100 (10, 15) #tricks#basic

#Antimicrobials are not always needed when you are feeling unwell. Antibiotics should only be prescribed by healthcare professionals after an appropriate diagnostic test. Be an #AntimicrobialResistance guardian.

#Antimicrobials are vital in fighting infectious diseases across humans, animals, and plants. However, their effectiveness is diminishing, leading to a growing and urgent crisis known as #AntimicrobialResistance. Let’s promote the responsible use and work together to combat #AMR.

#Handwashing is a basic and effective tool against infections. If we do not become sick, we would not need to use #antimicrobials. Encourage your loved ones to practice frequent #handwashing with soap under running water. Do your part to prevent #AntimicrobialResistance

#Antimicrobials are becoming less effective against common infections in animals & humans. 🚫 Do not self-medicate ✅ Visit a healthcare professional when sick Everyone has a role to play to ensure #antimicrobials continue to work. #AMR#WAAW2023

Every year, the National Antimicrobial Resistance Technical Working Group joins the global community to raise awareness of the dangers of misuse or overuse of #antimicrobials. Fighting #AMR is a global endeavour that must be addressed through a #OneHealth approach as evident in this year's theme of #WAAW2023: ‘Preventing #AntimicrobialResistance together” 🔗Press Release https://ncdc.gov.ng/news/504/nigeria-joins-the-global-community-to-commemorate-world-antimicrobial-awareness-week-%28waaw%29

Misuse or overuse of #antibiotics💊 & other #antimicrobials can reduce its effectiveness in treating common infections in animals & humans. From 18th-24th November, we are joining the global health community to mark the annual #WorldAntimicrobialAwarenessWeek2022 . #StayTuned

#AntimicrobialResistance is when medicines like #antimalarials, tetracycline, septrin, and amoxicillin no longer treat diseases they cured previously. Everyone everywhere, including users and non-users of #antimicrobials has a role to play to prevent #AMR. #BeAntimicrobialsAware
