Extracting a substring from string that is the last instance after a space in python

Question

I am new to python manipulation of strings. I have a collection of strings that have a similar format, two examples of the strings are as follows, ex1: "Graduated in 2015", ex2: "Graduates in 2022". The portion of these strings that I would like to extract are the years that is the string that is the last string without spaces. Using the above examples I would like to have an output of something like '2015' and '2020' and save these to a list. Is there a way to extract a substring using this criteria and save these to a list?

visually this is what I want

str1<-"Graduated in 2015" 
str2<-"Graduates in 2022"
#some code extracting the year substring and adding them to a list l
print(l)
['2015','2022']

Use [rsplit](https://docs.python.org/3/library/stdtypes.html#str.rsplit) with maxsplit = 1. — Chris Charley, Oct 27 '20 at 02:25

list_of_strings = ["Graduated in 2015", "Graduates in 2022"]

l = [s.split()[-1] for s in list_of_strings]

print(l)  # ['2015', '2022']

If it is in a fixed pattern you can split and use negative indexing:

str1 = "Graduated in 2015" 
str2 = "Graduates in 2022"
print([int(str1.split()[-1]),int(str2.split()[-1])])
