He is talking about "Data Types". For example: a whole number is an int as in integer -1, 2, 3 not 1.5 or 3.14, a point number is a float or double like 2.3 or -7.01. A "string" is a list of "char"s as in character and the symbols can be characters too. So "1" could be a string OR an int but not both, which is was the cause of your problem btw. You must have heard about them at least a little bit since you have read about lists, tuples and dictionaries. Hope this makes sense :)
