How to remove items from a string that are not contained in a list in Python

Question

I have a list of items:

items =["a", "b", "c"]

Now I want to scan a string containing the elements:

string = "a, b, c, d, e"

And remove d and e to get the following string of elements:

string = "a, b, c"

I have tried to use the remove() operator but it doesn’t solve the problem. I would appreciate your help. Thanks.

Answer 1

items = ["a", "b", "c"]
string = "a, b, c, d, e"

', '.join([i for i in string.split(', ') if i in items])

output:

'a, b, c'
