The reason for using NumPy to deal with random variables is that first, it has a broad range of different kinds of random variables. 使用NumPy来处理随机变量的原因是,首先,它有广泛的不同种类的随机变量。 And second, it’s also very fast. 第二,速度也很快。 Let’s start with generating numbe...
To put this differently, we model what we can,and whatever it happens to be left out, we attribute to randomness. 换一种说法,我们对我们能做的事情进行建模,不管发生什么,我们都将其归因于随机性。 These are just some of the reasons why it’s important to understand how to simulate random num...
There is no prerequisite for learning Python but it is best to have already knowledge of programming language as data types, variables, if-else, loops, function, etc You did not need to buy any software etc for this course You did not to learn any other programming langauge like C, C++...
