Arrange list by which word comes first in given sentence/string in Python

Question

I need the code to sort a list (of words) in the order by which they appear in a string (sentence).

For example:

list = ["small dog", "big dog", "medium dog"]

sentence = "Jack has a big dog not a small dog or medium dog."

Then the expected new_list would be:

new_list = ["big dog", "small dog", "medium dog"]

Thank you in advance!

Answer 1

You can sort by the position in the sentence by using sorted :

_list = ['small dog', 'medium dog', 'big dog']

sentence = "Jack has a big dog not a small dog or medium dog."

new_list = sorted(_list, key=sentence.find)

['big dog', 'small dog', 'medium dog']

You really don't want to use built-in names for variables such as list , dict , set , etc
