How to test if every item in a list of type 'int'?

Question

Say I have a list of numbers. How would I do to check that every item in the list is an int?
I have searched around, but haven\'t been able to find anything on this.

Answer 1

>>> my_list = [1, 2, 3.25]
>>> all(isinstance(item, int) for item in my_list)
False

>>> other_list = range(3)
>>> all(isinstance(item, int) for item in other_list)
True
>>>
