Syntax Errors vs Runtime Exceptions

Not every Python error happens at the same moment. This Block shows the difference between code Python cannot understand and valid code that fails while running. You will learn to recognize when execution began, follow what ran before a failure, and use the exception name as a useful clue.

What you will learn:

• Tell syntax errors apart from runtime exceptions
• Understand why syntax errors stop a script before normal execution
• Recognize ValueError, KeyError, IndexError, and FileNotFoundError
• Read a traceback from the bottom and locate the failing operation
• Distinguish exceptions from logic bugs that produce the wrong result

Leave with a simple habit: first check whether the code structure is valid, then ask which operation failed while the program was running.
