How to get a string after a specific substring?
The easiest way is probably just to split on your target word
my_string="hello python world , i'm a beginner "print my_string.split("world",1)
split takes the word(or character) to split on and optionally a limit to the number of splits.
In this example split on "world" and limit it to only one split.
I'm surprised nobody mentioned
def substring_after(s, delim): return s.partition(delim)
IMHO, this solution is more readable than @arshajii's. Other than that, I think @arshajii's is the best for being the fastest -- it does not create any unnecessary copies/substrings.
