## Python Regular Expression: Exercise-46 with Solution

Write a Python program to find all adverbs and their positions in a given sentence.

Sample Solution:-

Python Code:

``````import re
text = "Clearly, he has no excuse for such behavior."
for m in re.finditer(r"\w+ly", text):
print('%d-%d: %s' % (m.start(), m.end(), m.group(0)))
```
```

## Python: Tips of the Day

Getting the last element of a list:

some_list[-1] is the shortest and most Pythonic.

In fact, you can do much more with this syntax. The some_list[-n] syntax gets the nth-to-last element. So some_list[-1] gets the last element, some_list[-2] gets the second to last, etc, all the way down to some_list[-len(some_list)], which gives you the first element.

You can also set list elements in this way. For instance:

```>>> some_list = [1, 2, 3]
>>> some_list[-1] = 5 # Set the last element
>>> some_list[-2] = 3 # Set the second to last element
>>> some_list
[1, 3, 5]
```

Note that getting a list item by index will raise an IndexError if the expected item doesn't exist. This means that some_list[-1] will raise an exception if some_list is empty, because an empty list can't have a last element.
