10. The replace() function
Summary

## Instruction

Well done! Another interesting function is replace(old, new). It replaces all instances of old with new in a string. Take a look:

story = ('Anne was hungry, so she went to a restaurant. '
'When the waiter came up to her, Anne ordered some vegetarian dishes.')
print(story.replace('Anne', 'Katherine'))


When we print the story, the protagonist's name will be changed to Katherine.

## Exercise

Given an article about Pythonidae, print its contents with every sentence beginning on a new line.

### Stuck? Here's a hint!

Use the replace() function to find every instance of a period followed by a space. Replace those instances with a period followed by the newline character (\n).
