# Python Error and Exception Handling

Errors and exceptions can be handled in Python using `try...except` blocks.

## `try...except`

The `try` block lets you test a block of code for errors. The `except` block lets you handle the error.

```python
try:
  print(x)
except:
  print("An exception occurred")
```

## `finally`

The `finally` block, if specified, will be executed regardless if the `try` block raises an error or not.

```python
try:
  print(x)
except:
  print("Something went wrong")
finally:
  print("The 'try except' is finished")
```

## Raising an Exception

You can raise an exception using the `raise` keyword.

```python
x = -1

if x < 0:
  raise Exception("Sorry, no numbers below zero")
```
