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

The sunrays taking; All the darkness away, Love taking all hatred away, Miniature hopes in shapes of stars, Now subsiding in beautiful destiny, Happiness taking all the pain away. In midst the beautiful world, I laid here, Breathless, My sould taken away by you, My heart given to beat in someones Else's cage, My body drifted with fire, My voice taken away by deafening silence, My memories now, washed away, Fading away with new ones. This is how, A beautiful day began, Changing my life, To be dreadful forever, In midst the beautiful world, I laid here as a dead lover. #tyler#review

She's like a poem, Waiting to be read. She's like a song, Waiting to be sung. She's like a melody, Waiting to be heard. She's like a book, Waiting to be understood. She's like a dance, Waiting to be performed. She's like a beauty, Waiting to be cherished. She's like art, Waiting to be crafted. She's you, Waiting to be found. She's you, Waiting to be loved. She's not just a girl, She's within all of you, She resides somewhere inside, Somewhere the golden rays don't reach, Somewhere the silver shine doesn't work, Somewhere in you, She stays, Waiting to be acknowledged. #tyler#review

During a dreadful night, I managed to put up a fight. Maybe the strong me died, And weak me survived. The constant voices in my ears, Here I am living in my fears. Like a painful reminder of that night, Where I lost a outnumbered fight. Wondering if I am even right, While holding myself tight. The night is long dead, Here my tears still wetting my bed. That dreadful night, The cause of my fright. These thoughts make me shiver, The fear making me quiver. My painful screams, Still haunting my dreams. Maybe the strong in me died, And weak me survived. I haven't given up the fight, Because I know, I can still make it right. #tyler#review
