Think Bayes: Bayesian Statistics Made Simple is an introduction to Bayesian statistics using computational methods. Larger pieces, like recursion and object-oriented programming are divided into a sequence of smaller steps and introduced over the course of several chapters. As luck would have it, this just so happens to also be the next line of code in our program. It is even better if you follow along and try out these examples at your shell.
Generate a random number between two provided values. In our program, the odds variable is assigned a list of numbers, so odds is a list in this case. We now know what we want to do.

The only way you can be sure is to use the nonspecific import statement that is, put import A and import B in your code , then invoke the specific F you want using either A.
Q: Q: But, surely, compilation has to happen at some stage? In this loop, we use range to generate a list of numbers that are assigned one at a time to the num variable: You now know that you can use a for loop to repeat the five lines of code at the bottom of this program five times.
