In Python, exception handling is done using the try, except, else, and finally blocks. It allows you to handle errors gracefully without crashing the program.
Explanation:
-
try: Wrap code that might raise an error.
-
except: Catches and handles specific exceptions. You can have multiple
exceptblocks for different exception types. -
else: Runs only if the
tryblock doesn’t raise any exceptions. -
finally: Executes no matter what—used for cleanup actions like closing files or releasing resources.
