+My first tutorial for Real Python got published 🎉
+
+"Python Thread Safety: Using a Lock and Other Techniques": [https://realpython.com/python-thread-lock/](https://realpython.com/python-thread-lock/)
+
+### Why thread safety?
+
+Below is a classic example of creating a singleton class is Python:
+
+```python
+class SingletonClass(object):
+  def __new__(cls):
+    if not hasattr(cls, 'instance'):
+      cls.instance = super(SingletonClass, cls).__new__(cls)
+    return cls.instance
+```
+
+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.
