Python Thread Safety - My First Tutorial for Real Python
My first tutorial for Real Python got published π
"Python Thread Safety: Using a Lock and Other Techniques": https://realpython.com/python-thread-lock/
Why thread safety?
Below is a classic example of creating a singleton class is Python:
π€ππ’π΄π΄ ππͺπ―π¨ππ¦π΅π°π―πππ’π΄π΄(π°π£π«π¦π€π΅):
β π₯π¦π§ π―π¦πΈ(π€ππ΄):
β β πͺπ§ π―π°π΅ π©π’π΄π’π΅π΅π³(π€ππ΄, 'πͺπ―π΄π΅π’π―π€π¦'):
β β β π€ππ΄.πͺπ―π΄π΅π’π―π€π¦ = π΄πΆπ±π¦π³(ππͺπ―π¨ππ¦π΅π°π―πππ’π΄π΄, π€ππ΄).__π―π¦πΈ__(π€ππ΄)
β β π³π¦π΅πΆπ³π― π€ππ΄.πͺπ―π΄π΅π’π―π€π¦
The SingleTonClass is supposed to have only 1 object, but the code can lead to the creation of more than one instances when executed in a multithreaded environment.
Read the tutorial to spot such race conditions and learn to fix them using Python's synchronization primitives.
