These both need to be character strings (or strings for short), so we put them in quotes. Numpy.loadtxt has two parameters: the name of the file we want to read, and the delimiter that separates values on a line. This dotted notation is used everywhere in Python to refer to the parts of things as ponent. The expression numpy.loadtxt(.) is a function call that asks Python to run the function loadtxt which belongs to the numpy library. A general term could be that the function is a component of the library. Functions that are part of an imported library, as the above example of numpy.loadtxt() are written with the library name as a suffix, and separated by a dot for clarity. What is dotted notation? Functions that are built-in the langage, like print() are simply called by their name. A simple example of a function is print() that is built-in the python langage.

What is a function? Functions can be part of a library or created by the user as “user-defined functions.”' A Function is a block of code written to perform a specific task, and can be re-used to provide modularity. Use the pyplot library from matplotlib for creating simple visualizations.Use an(array, axis=0) or an(array, axis=1) to calculate statistics across the specified axis.Use an(array), numpy.max(array), and numpy.min(array) to calculate simple statistics.Use # some kind of explanation to add comments to programs.All the indexing and slicing that works on arrays also works on strings.Use low:high to specify a slice that includes the indices from low to high-1.Use array to select a single element from an array.The expression array.shape provides the shape of an array ( i.e.Use print(something) to display the value of something.Variables are created on demand whenever a value is assigned to them.

Use variable = value to assign a value to a variable in order to record it in memory.

Use the numpy library to work with arrays in Python.

Import a library into a program using import libraryname.
