Playback Speed

Some people have a habit of ~~lecturing~~ speaking rather quickly, and it’d be nice to slow them down, a la YouTube’s 0.75 playback speed, or even by having them pause between words.

In a file called playback.py, implement a program in Python that prompts the user for input and then outputs that same input, replacing each space with ... (i.e., three periods).

Hints

Recall that input returns a str, per docs.python.org/3/library/functions.html#input.
Recall that a str comes with quite a few methods, per docs.python.org/3/library/stdtypes.html#string-methods.

Demo

How to Test

Here’s how to test your code manually:

Run your program with python playback.py. Type This is CS50 and press Enter. Your program should output:
```
This...is...CS50    
```
Run your program with python playback.py. Type This is our week on functions and press Enter. Your program should output:
```
This...is...our...week...on...functions
```
Run your program with python playback.py. Type Let's implement a function called hello and press Enter. Your program should output
```
Let's...implement...a...function...called...hello
```
