Skip elements on a condition based in a list comprehension in python

Question

I have a list List:

List = [-2,9,4,-6,7,0,1,-4]

For numbers less than zero (0) in the list , I would like to skip those numbers and form an

Answer 1

First use lower case for variable names, second don't use list because it reserved name.

Then just do an if inside the list comprehension

my_list = [i for i in init_list if i >= 0 ]

Answer 2

You have many options to achieve that. With a list comprehension you can do:

my_list = [i for i in my_list if i>=0]

With filter():

my_list = filter(lambda i: i>=0, my_list)

Note:

In Python 3, filter() returns a filter object (not list), to convert it to a list, you can do:

my_list = list(filter(lambda i: i>=0, my_list))
