Bases: Protocol

Strategy interface that declares a common behavior for all supported algorithms.

execute()

Execute the strategy’s algorithm.

Return type:

str

Returns:

A string result of the algorithm.

class ConcreteStrategyA

Bases: object

A concrete strategy implementing a specific algorithm.

execute()

Execute ConcreteStrategyA’s algorithm.

Return type:

str

Returns:

A string result indicating the execution.

class ConcreteStrategyB

Bases: object

A concrete strategy implementing another algorithm.

execute()

Execute ConcreteStrategyB’s algorithm.

Return type:

str

Returns:

A string result indicating the execution.

class Context

Bases: object

Context class that maintains a reference to a strategy object.

__init__()

Initialize the context without a strategy.

Return type:

None

set_strategy(strategy)

Set the current strategy.

Parameters:

strategy (Strategy) – The strategy to use.

Return type:

None

execute_strategy()
