SWEN-123 Lecture Notes - List Comprehension & 2D Lists

Flashcards about List Comprehension and 2D Lists in Python.

parentheses

A tuple is created by enclosing a comma separated list of values between _.

TypeError

Trying to change a value inside a tuple will raise a _ because tuples do not support assignment.

tuple()

The built in _ function can create a tuple from another sequence.

tuple()

The _ function will create a tuple from any sequence.

packer

Open your activities module and add a function called _ that returns at least 4 values of your choice.

list()

Using the built-in _ function that will return any sequence as a list, e.g. a = list(range(10))

list()

Calling the _ function will return any sequence as a list

swapper

Open your activities module and add a new function named _ that declares a parameter for a_list.

[:]

Slicing uses a special operator, _, to create a new list by selecting specific values from an existing list.

start

If _ is omitted, it defaults to 0.

stop

If _ is omitted, it defaults to length.

chunky

Open your activities module and add a new function called _ that declares parameters for a_list and a size.

sort()

Calling the _ function on a list will perform an in- place sort on the values in the list.

sorted()

Calling the _ function will return a sorted copy of the list passed in as a parameter to the function

reverse

Setting the named _ parameter to True will sort the list in reverse order.

comprehension

List _ is a syntactic shortcut that can be used to copy the elements of any sequence into a list.

comprehension

Open your activities module and add a function named _.

2D

A _ list is simply a list of lists.

make_table

Open your activities module and add a new function named _ that declares parameters for rows, columns, and a default value.

tictactoe.py

Create a new Python module in a file named _ and add a function called “make_board” that creates and returns a Tic-Tac-Toe board.

make_move

Open your tictactoe module and add a function called _ that declares a parameter for the board and the current symbol (i.e. "X" or "O")
