FunnyDeco
Collection of useful decorators for python projects
Implements:
- Benchmarking util for methods
- Singleton pattern realisation for classes
Installation:
pip install funnydeco
Examples:
1. Benchmark decorator
from funnydeco import benchmark
# noinspection PyUnusedLocal
@benchmark
def long_loop(print_benchmark=False, benchmark_name='') -> int:
"""
Demo class for example of benchmark
"""
result = 0
for i in range(int(1e7)):
result += i
return result
if __name__ == '__main__':
print('With benchmark:')
long_loop(print_benchmark=True, benchmark_name='Long loop procedure')
print('Without benchmark:')
long_loop()2. Singleton decorator
from funnydeco.core import singleton, SingletonReseter
from time import sleep
@singleton
class SlowInitClass(SingletonReseter):
"""
Demo class for example of singleton decorator
"""
def __init__(self):
self.variable = 1
print("I'm sleeping...")
sleep(3)
print("I'v woken up!")
if __name__ == '__main__':
print('First dumbass init:')
dumbass1 = SlowInitClass()
print(f'variable={dumbass1.variable}')
dumbass1.variable = 2
print()
print('Second dumbass init:')
dumbass2 = SlowInitClass()
print(f'variable={dumbass2.variable}')
print()
print('Third dumbass init:')
print('Temporary stopping singleton behaviour')
SlowInitClass().reset_singleton()
dumbass3 = SlowInitClass()
print(f'variable={dumbass3.variable}')
dumbass3.variable = 3
print()
print('Fourth dumbass init:')
dumbass4 = SlowInitClass()
print(f'variable={dumbass4.variable}')
print()If you do not need to use reset_singleton functionality you may not to inherit your class from SingletonReseter
