Study Notes
Python Collection Types
- Python uses collection data types to store multiple data points efficiently
- Types are categorized into sequence and non-sequence types
- Sequence types maintain order and allow indexed access (e.g., str, list, tuple, range)
- Non-sequence types don't maintain order and don't support indexing (e.g., set, dict)
Sequence Data Types: Lists
- A list is an ordered and mutable collection in Python
- Elements are enclosed with square brackets
[] - Can store items of different types (homogeneous or heterogeneous)
- List elements are accessed via indices (starting from 0)
- Positive indices access from the beginning, negative indices from the end
- Example:
days = ["Monday", "Tuesday", ...]
Built-in List Functions
-
len(): Returns the number of items in a list -
type(): Returns the data type of an object -
max(): Returns the largest value in a list -
min(): Returns the smallest value in a list -
sum(): Returns the sum of all numbers in a list
Accessing List Elements
- Elements are indexed starting at 0 (using positive indices)
- Elements can also be accessed from the end of the list using negative indices (-1 is the last element)
- Example:
first_day = days[0],last_day = days[-1]
Common Error: IndexError
- Occurs when trying to access an invalid index (one that's out of range)
Mutability of Lists
- Lists are mutable: means you can change their elements after creation
- You can add, remove, or change elements without creating a new list
Modifying List Elements
- Use indexing to change an element’s value:
grades[2] = 85
List Packing Using append()
- Adds elements to the end of the list:
student_scores.append(95) - Can be used in for loops:
even_numbers.append(num)
List Packing Using +=
- Adds elements to the end of a list using the addition operator (
+=) - Requires an iterable on the right-hand side;
grades += [80]
List Packing Using list()
- Converts iterable objects (strings, ranges, and tuples) into lists:
number_list = list(number_range)
List Comprehension
- Creates new lists from existing ones efficiently
- Syntax:
new_list = [expression for item in iterable if condition]
Notable List Methods
-
append(): Adds an item to the end of the list -
insert(): Inserts an item at a specific index -
extend(): Adds all items from an iterable to the end of the list -
count(): Counts the occurrences of a specific item -
index(): Returns the index of the first occurrence of an item -
remove(): Removes the first occurrence of a specified item -
pop(): Removes and returns an item at a specified index (or the last item if no index is given) -
sort(): Sorts the list in-place (in ascending order) -
reverse(): Reverses the order of items in the list, in-place -
copy(): Returns a shallow copy of the list -
clear(): Removes all elements from the list
Tuple Data Type
- Immutable (cannot change once created): values cannot be modified after creation
- Values are enclosed in parentheses
();empty_tuple = ()optionallyplaylist_1 = ('Rock', 'Jazz', 'Pop') - Values are accessed via indices, just like lists
Tuple Immutability
- Attempting to modify a tuple element results in a TypeError:
’tuple’ object does not support item assignment
Using += with Tuples
- The
+=operator creates a new tuple, it doesn't modify the original tuple. - Example:
tuple_b += tuple_c
Tuple Methods
-
count(): Returns the number of times an item appears in the tuple -
index(): Returns the index of the first occurrence of a specific item
Tuple Slicing
- Extracts a subset of a tuple (similar to lists) using slicing notation
- Syntax:
sequence_identifier[start_index: end_index: step_size]
Dictionary Data Type
- Unordered collection of key-value pairs
- Keys must be unique and immutable (e.g., strings, numbers, tuples)
- Values can be of any data type
Dictionary Methods
-
get(): Retrieves a value associated with a key (or a default value if the key doesn't exist) -
keys(): Returns a view object containing all keys -
values(): Returns a view object containing all values -
items(): Returns a view object containing all key-value pairs as tuples -
copy(): Creates a shallow copy of the dictionary -
update(): Updates a dictionary with key-value pairs from another dictionary or iterable -
clear(): Removes all items from the dictionary
Dictionary Operators
-
in: Checks if a key exists -
not in: Checks if a key doesn't exist -
==: Checks if two dictionaries have the same key-value pairs -
!=: Checks if two dictionaries are not equal
Using del with Dictionaries
- Deletes key-value pairs or entire dictionaries
- Example:
del Dog_dict ['age']
Generator Expressions
- Syntax:
(expression for item in iterable if condition) - Unlike lists, it doesn't store all values in memory at once. Useful for large datasets.
Set Data Type
- Unordered collection of unique elements
- Elements are enclosed in curly braces
{} - Duplicate elements are ignored
Set Methods
-
add(): Adds an item to the set -
update(): Adds multiple items from an iterable -
remove(): Removes an item; raises an error if the item doesn't exist -
discard(): Removes an item, but no error is raised if the item doesn't exist -
clear(): Removes all elements from the set
Set Operators
-
|: Union -
&: Intersection -
-: Difference -
^: Symmetric Difference -
<=: Subset -
>=: Superset -
<: Strict Subset -
>: Strict Superset
Frozenset Data Type
- Immutable version of a set; it cannot be modified after creation
- Elements cannot be added or removed; otherwise a
AttributeErroroccurs.
List/Tuple/Dictionary/Set Summary Table
- A table summarizing characteristics of different collection types like mutability, sequence behavior, order, supporting slicing, and allow duplicates.
