def int(x):
    a=[]
    for i in x:

I tried to make a list consist of integers from given list but output is [].
What is wrong?
What ı want to do:

You can do this filtering using isinstance in a list comprehension

>>> data = [1,2,3,"a"]
>>> [i for i in data if isinstance(i, int)]
[1, 2, 3]

As a side note do not shadow the name int with your function name, nor the function name input with your variable name.
