This document contains lecture notes on multi-threading and exception handling in Python programming. It discusses syntax errors that occur due to incorrect code, defines exceptions as events that disrupt normal program flow, and lists some built-in Python exceptions. It also explains how to catch exceptions using try/except blocks, where the except clause handles any exceptions that occur in the try block. The document was presented by M Dyva Sugnana Rao on multi-threading as part of a Python programming course for Computer Science students.
