NumPy Essentials

Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "Note that SciPy can mean a number of thing, like the Python module named scipy."

A block of code is set as follows:

In [42]: print("Hello, World!")

Any command-line input or output is written as follows:

In [6]: x
Out[6]:
array([[1, 2, 3],
       [2, 3, 4]])
In [7]: x[0,0]
Out[7]: 1
In [8]: x[1,2]
Out[8]: 4

New terms and important words are shown in bold.
