5. Sequences: Lists and Tuples

Objectives

In this chapter, you’ll:

• Create and initialize lists and tuples.
• Refer to elements of lists, tuples and strings.
• Sort and search lists, and search tuples.
• Pass lists and tuples to functions and methods.

Objectives (cont.)

• Use list methods to perform common manipulations, such as searching for items, sorting a list, inserting items and removing items.
• Use additional Python functional-style programming capabilities, including lambdas and the operations filter, map and reduce.

Objectives (cont.)

• Use functional-style list comprehensions to create lists quickly and easily, and use generator expressions to generate values on demand.
• Use two-dimensional lists.
• Enhance your analysis and presentation skills with the Seaborn and Matplotlib visualization libraries.
