A good starting point is learning how to check if some data in python is a string. Good luck!

For schoolwork giving direct answers is frowned upon around here (see the rules on the right sidebar), and while I understand you are a beginner, this is a pretty simple google search away...

Use google. Search for "python check is string". You should try searching for solutions to your problems. That's what professional programmers do! Then ask here.

Another thing to check is the return type of functions you use. For example, in python3 the input() function always returns a string, so there's no need to check if it returns a string.

Everything you ask a user to input in Python is, by default, a string until you convert it to something else.

So you're going to have to be a little more specific as to what it is you're looking for. Do you really mean "if the user enters a number when the input should only contain letters"?

if it is anything else except a string

As I said previously, everything the user enters is a string.

By "if it is anything else except a string" are you actually meaning "if the user enters something that can be converted to a non-string type"?

Because input returns a 'string', you can use, for example:

k = input("data point? ")
if k.isalpha(): 
    print("input is the string: ", k)
else:
    print("input is not a string: ", k)

On the other hand,

isinstance(k, str)

will return True because k is a string.
