Study Notes

Lists

A list is a sequence of data values, also called items or elements.
Each item in a list has a unique index that specifies its position, starting from 0.
Lists are mutable, meaning their elements can be inserted, removed, or replaced.

List Literals

Lists can include various data types like strings, integers, or even other lists, using square brackets [ ].
To create a list with values of an expression, include the expression within the list literal.
The range() function generates a sequence of integers suitable for creating lists.
The list() function converts any iterable sequence, like a string, into a list.

List Methods

len() returns the number of elements in a list.
[] is used to access elements by index.
: is used to access a range of elements.
+ (concatenation) combines two lists into a new list.
== (equality) compares two lists for identical content.
in checks if an element exists within the list.
print() displays the contents of a list.

Replacing Elements

The subscript operator [] is used to replace an element at a specific index.
The for loop can be used to iterate through a list, replacing each element with its square, or manipulating each word in a string by converting it to uppercase.

Inserting and Removing Elements

The append() method adds an element to the end of a list.
The extend() method adds all elements of another list to the end of a list.
The insert() method inserts an element at a specified index in a list.
The pop() method removes and returns the element at the end or a specific index of the list.
