return length of string with given index????

[lostbuttrying]

This is the exact question given...I wish I could start or make a stab, but I don't know where to begin:

Submit a Python file named, 'countDemo.py', that defines and demonstrates a function that takes a list of strings and an index and returns the length of the string with the given index. If the index is not valid, the function should return a value of -1.

Thank you in advance for any help or insight anyone can give........

In a file named 'countDemo.py', write something like

def StringListIndexer(strList, index): 
	if index > len(strList):
		return -1 # Return causes an immediate exit of the function
	return len(strList[index])

Then, in the same file you'll want some test code:

 
aListOfStrs = ['hi', 'hello', 'goodbye']
# remember that the first one is number zero
print StringListIndexer(aListOfStrs, 1)
