`KeyboardInterrupt` is an exception in Python that is raised when the user interrupts the execution of a program by pressing `Ctrl+C` on the keyboard. This exception can be caught using a `try-except` block, like this:
```
try:
# Some code that may raise KeyboardInterrupt
except KeyboardInterrupt:
# Code to handle the exception
```
By catching the exception, you can perform some cleanup operations before exiting the program. For example, you might want to close any open files or connections, or save any unsaved data.

In Python, the `KeyboardInterrupt` exception is raised when the user interrupts the execution of a program by pressing Ctrl+C. To handle this exception, you can use a try-except block. Here's an example:
```python
try:
# Code that may raise KeyboardInterrupt
# ...
except KeyboardInterrupt:
print("Program interrupted by the user.")
```
In the above code, if a `KeyboardInterrupt` exception is raised, the program will print the message "Program interrupted by the user." instead of abruptly terminating.
