Thats an interesting exercise which most of us here already
know how to do it and don't have much motivation to do it.
I assume its a homework and you would like some help?
But you don't ask any questions... or show us any code.

We won't do your homework for you but we will offer assistance
if you show us your work, and we can suggest ways to progress.

For example, there is a statistics module in the python
standard library.

In the meantime do you know how to read data from a file?
Do you know anything about the different data formats?
How to read them into a consistent data format in your program?

I'd expect your code to be structured like this:

def mean(lst):....
def std(lst):....

for file in <your two filenames>
    numlist = read data from file
    print(file, "mean: ", mean(numlist))
    print(file, "SD: ", std(numlist)

If you have specific questions get back to us, include any
error messages in full please.
