1. Write a fruitful function with at least one string parameter that returns an integer. This could be something like counting the number of commas in the string.
2. Write a fruitful function with at least one string parameter that returns another string. This could be something like returning a new string with every other character from the original string.
3. Write a fruitful Boolean function with at least one string parameter and one other parameter. This could be something like returning True if the string has the specified number of commas.

Be sure to document what your function does and what the parameters are!!!!

Do NOT give an example of how to call the function. Other students have to figure it out from your detailed description of the parameters being passed.
