Python Set symmetric_difference() Method
Returns a new set with items from all the sets, except common items
Usage
The symmetric_difference() method returns a new set containing all items from both the sets, except common items.
If you want to modify the original set instead of returning a new one, use symmetric_difference_update() method.
The symmetric difference is actually the union of the two sets, minus their intersection.
Syntax
set.symmetric_difference(set)
| Parameter | Condition | Description |
| set | Required | A set to find difference in |
Basic Example
# Compute the symmetric difference between two sets
A = {'red', 'green', 'blue'}
B = {'yellow', 'red', 'orange'}
print(A.symmetric_difference(B))
# Prints {'orange', 'blue', 'green', 'yellow'}
Equivalent Operator ^
Set symmetric difference can be performed with the ^ operator as well.
A = {'red', 'green', 'blue'}
B = {'yellow', 'red', 'orange'}
# by method
print(A.symmetric_difference(B))# Prints {'orange', 'blue', 'green', 'yellow'}# by operator
print(A ^ B)
# Prints {'orange', 'blue', 'green', 'yellow'}Symmetric Difference between Multiple Sets
The symmetric_difference() method doesn’t allow multiple sets.
However, using ^ operator, you can find symmetric difference between multiple sets.
A = {'red', 'green', 'blue'}
B = {'yellow', 'orange'}
C = {'blue', 'red', 'black'}
print(A ^ B ^ C)
# Prints {'orange', 'black', 'green', 'yellow'}

Two Machine Learning Fields
There are two sides to machine learning:
- Practical Machine Learning:This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
- Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
