Method chaining—lets you chain method calls together on a single line so the output of one becomes the input to another. Method chains are read left to right.
myText = data().strip().split(',')
In this example, strip removes the unwanted leading and trailing white space in the text referenced by the variable data, and then the split extracts the strings separted by commas. A list is created and assigned to MyText. Notice that methods are executed from left to right.
