Chapter 12 - Think Python - Understanding Tuples and Iterators

What is a tuple?

• A mutable sequence of elements

• An immutable sequence of elements

• A sequence that can change size

• A sequence with only one element

What does tuple assignment involve?

• Assigning a single value to multiple variables

• Assigning a sequence to a single variable

• Assigning a sequence to a tuple of variables

• Assigning a single value to a single variable

What is the operation of assembling a variable-length argument tuple called?

• Scatter

• Gather

• Zip

• Iterate

What does the scatter operation involve?

• Treating a sequence as a single argument

• Treating a sequence as a list of arguments

• Treating a sequence as a dictionary

• Treating a sequence as a tuple

What is the result of calling a built-in function zip?

• A list of integers

• A zip object

• A single integer

• A dictionary

What is an iterator?

• An object that can iterate through a sequence

• An object that stores a single value

• An object that provides list operators

• An object that is immutable

What is a data structure?

• A single integer

• A collection of related values

• A single string

• A single boolean

What is a shape error?

• An error caused by a missing value

• An error caused by a value having the wrong shape

• An error caused by a syntax mistake

• An error caused by a missing operator

What does a zip object do?

• Iterates through a sequence of integers

• Iterates through a sequence of tuples

• Iterates through a sequence of strings

• Iterates through a sequence of dictionaries

What does an iterator not provide?

• List operators and methods

• Sequence iteration

• Tuple assignment

• Data storage
