1. Ultimate Reference to Python Set Methods
Python language provides a list of built-in set methods that work on sets. In this tutorial, we will provide you with all the set methods or functions in alphabetical order. Further, these methods are also called set functions, but these rely only on their parent class. Usually, these methods are built-in in Python programming language and we can use them to work with sets as required. The table below contains all the built-in set methods in this language and serves as an ultimate and up-to-date guide or reference.
2. Search Ultimate Reference For Python Set Methods
Search Python set methods from the below table, which is an ultimate and up-to-date guide or reference, for the developers. Please note that the parameters or arguments of some methods might be optional, so don't worry while writing your Python programs.
2.1. Alphabetical Reference
| Method | Description |
| add() | Python lets you add an element to the set using this method. |
| clear() | This Python method clears all the elements from a set. |
| copy() | To create a copy of a set, we use this Python method. |
| difference() | A new set is formed, which contains the difference of two or more Python sets using this method. |
| difference_update() | This Python method removes the elements in the current set that are also present in another specified set. |
| discard() | To remove a specific element from the set, we can use this Python method. |
| intersection() | This Python method returns a new set, the intersection of two or more sets. |
| intersection_update() | This Python method removes the elements in the current set that are not present in another specified set. |
| isdisjoint() | It returns a boolean (True, False) output whether the two Python sets have overlapping or similar elements or not. |
| issubset() | It returns a boolean (True, False) output whether another set contains this set or not. |
| issuperset() | It returns a boolean (True, False) output whether this set contains another set or not. |
| pop() | This Python method removes a random element in a set and returns it. |
| remove() | To remove a specified set element, we use this Python method. |
| symmetric_differnce() | This Python method returns a new set with all the common elements in both sets removed. |
| symmetric_difference_update() | This Python method updates the current set with the values of other sets removing the common elements. |
| union() | To create a union of two sets, we use this Python method. |
| update() | To update the set with another set or iterable, we can use this Python method. |
3. Dynamically Get Python Set Methods
The Python language pack contains all the built-in methods to apply on sets and fortunately, we can retrieve that list dynamically from the distribution. Use the following code to acquire the up-to-date and ultimate list of Python set methods.
Get All Set Methods
# Get the list of set methods
set_methods = [
method
for method in dir(set)
if callable(getattr(set, method))
and not method.startswith('__')
]
# Print the list of set methods
print(set_methods)
Note:
Importantly, it is important to note that these methods are different from those of built-in Python functions, so make sure to keep this in mind.
4. Reference Links
In this reference tutorial, we collected resources and material from the below websites to write up a clear, up-to-date, and ultimate guide to Python set methods or functions that depend on specific classes.
- We explored W3schools.com as a reference to build up this ultimate guide of all Python set methods or class-dependent functions.
- Also, we consulted Python's official reference to finalize our list of set methods or class-dependent functions.
