Find a specific word from a list in python

Question

So I have a list like below-

list = [scaler-1, scaler-2, scaler-3, backend-1, backend-2, backend-3]

I want to create another list from it with the words which starts with 'backend'.How can i do that ?

Please note the content of the list will change from system to system, I want my code to be dynamic, any help?

here's a hint: there is a built-in `str` method called `startswith` — juanpa.arrivillaga, Oct 12 '16 at 10:38
do `newlst = [i for i in _list if i.startswith("backend")]`. — lycuid, Oct 12 '16 at 10:39
What do you mean by "want my code to be dynamic"? What is dynamic here? — Sayse, Oct 12 '16 at 10:41

First off, do not use the name list for assignment to your objects, you'll shadow the builtin list type.

Then, you can use a list comprehension with str.startswith in a filter:

new_lst = [x for x in lst if x.startswith('backend')]
