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

See functions

def is_int(x):
    if type(x) == int:
        return True
    return


def all_int(a):
    for i in a:
        if not is_int(i):
            return False
    return True

Then call

all_int(my_list) # returns boolean
