Multithreaded
This method provide proper handling for multi-thread environment by closing public threading lock while creating instance of Singleton subclass.


Installation
Just use (No other package is needed):
$ pip install pattern-singleton


Example Usage
from pattern_singleton import Singleton


class Example(metaclass=Singleton):
def __init__(self):
self.variable = 1


if __name__ == '__main__':
example_01 = Example()
example_02 = Example()

print(example_01.variable) # displays 1
print(example_02.variable) # displays 1

example_01.variable = 2 # changes value for every instance of Example class

print(example_01.variable) # displays 2
print(example_02.variable) # displays 2
