Filter a list in python get integers

Question

I have a list:

[\'Jack\', 18, \'IM-101\', 99.9]

How do I filter it to get only the integers from it??

I tried

map(i         


        

Answer 1

Use list comprehension

>>> t = ['Jack', 18, 'IM-101', 99.9]
>>> [x for x in t if type(x) == type(1)]
[18]
>>> 

map(int, x) throws an error

map function applies int(t) on every element of x.

This throws an error because int('Jack') will throw an error.

[Edit:]

Also isinstance is purer way of checking that it is of type integer, as sukhbir says.
