刚接触python不久，像这种题应该用什么代码啊，都不知道搜什么
(4) Write a code for computing the following conditional probabilities for each data series:
1 Prob (stock price increases at t | stock price increases at t − 1)
2 Prob (stock price increases at t | stock price decreases at t − 1)
3 Prob (stock price decreases at t | stock price increases at t − 1)
4Prob (stock price decreases at t | stock price decreases at t − 1)
5 Prob (stock price increases at t | stock price increases at t − 1 and t − 2)
6 Prob (stock price decreases at t | stock price decreases at t − 1 and t − 2)
这里有讲到条件概率的计算方法，可以看一下
