Before class, we'd like you to define a function that takes one string as input and returns the string repeated. For example, if the input is 'cat', the function should return 'catcat'.

Hint: Be sure to read the pre-reading about defining functions! If your solution doesn't say def somewhere in it, you're not defining a function, but there's more to it than just saying def.

Some notes on submitting and grading blocks of code in pre-lecture assignments, like in this problem:

1. You will find it beneficial to use a Jupyter Notebook to develop your solution to this problem and the next, and then copy your answer here.
