Python instance check

Like any other programminmg languages, Python also provides a way to check what the type of the instance is.
Simple, by using 'isinstance' or 'type' function, it is possible to check instance's type.

the following code is about using 'isinstance and type'

val = 7
ovals = [1, 2]
vals = []
if isinstance(val, int):
    vals += val,

if type(ovals) == list:
    vals += ovals
