# Python Built-in Methods – Python Set issuperset() Method

Determines whether all items in the specified set are present in the original set

## Usage

The `issuperset()` method returns True if all items in the specified set are present in the original set, otherwise FALSE.

## Syntax

set.issuperset(set)

 Parameter Condition Description set Required A set to search for common items in

## Basic Example

``````# Check if all items in B are present in A
A = {'red', 'green', 'blue', 'yellow'}
B = {'yellow', 'red'}
print(A.issuperset(B))
# Prints True``````

## Equivalent Operator >=

You can achieve the same result by using the `>=` comparison operator.

``````A = {'red', 'green', 'blue', 'yellow'}
B = {'yellow', 'red'}
print(A >= B)
# Prints True``````

## Find Proper Superset

To test whether the set is a proper superset of other, use `>` comparison operator.

Set A is considered a proper superset of B, if A is a superset of B, but A is not equal to B.

``````# Check if A is a proper superset of B
A = {'red', 'green', 'blue', 'yellow'}
B = {'yellow', 'red'}
print(A > B)
# Prints True

# Check if A is a proper superset of B
A = {'yellow', 'red'}
B = {'yellow', 'red'}
print(A > B)
# Prints False``````

## 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.
