+Combining Python's [Getters and Setters](https://brandonrozek.com/blog/pygetset/) with locks can give us seamless thread-safe variable access.
+
+```python
+from threading import Lock
+class Person:
+    def __init__(self):
+        self._age = 0
+        self.age_lock = Lock()
+    @property
+    def age(self):
+        a = None
+        with self.age_lock:
+            a = self._age
+        return a
+    
+    @age.setter
+    def age(self, a):
+        with self.age_lock:
+            self._age = a
+```
