Improper async programming causes deadlocks and synchronization issues

Incorrect use of asynchronous programming patterns leads to deadlocks, race conditions, and synchronization issues that can cause application hangs or crashes.

Use debugging tools like PDB, PyCharm debugger, or VS Code debugger to identify deadlock conditions. Review async task dependencies and ensure proper task chaining. Avoid blocking operations in async contexts. Test with integration tests using Pytest or Unittest.
