Test type of elements python tuple/list

by 
all(isinstance(n, int) for n in lst)

Demo:

In [3]: lst = (1,2,3)

In [4]: all(isinstance(n, int) for n in lst)
Out[4]: True

In [5]: lst = (1,2,'3')

In [6]: all(isinstance(n, int) for n in lst)
Out[6]: False

Instead of isinstance(n, int) you could also use type(n) is int
