There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, filenames, or name of functions. Here is an example: "Most of the preceding code is for plotting; the probabilistic part is performed by the y = stats.norm(mu, sd).pdf(x) line."

A block of code is set as follows:

μ = 0.
σ = 1.
X = stats.norm(μ, σ)
x = X.rvs(3)

Bold: Indicates a new term, an important word, or words that you see onscreen.
