When you catch an exception (error), you can save information about this exception using the `as` keyword.

The full alias structure:

```python
except {error_type} as {variable_name}:
    # code block
```

The alias allows us to display information about caught errors.  
Look at the example:

try:
    a = "string" + 10
except TypeError as error:
    print("TypeError:", error)

print("The following code should be executed:")
print("5 + 10 =", 5 + 10)
