How to Isolate a Substring After a Specific Occurrence
Obtaining a substring after a specified substring is a frequent task in programming. Consider the scenario where you have the string "hello python world, I'm a beginner" and need to extract the string after the word "world". The desired output is ", I'm a beginner".
Solution Using String Splitting
A straightforward approach to solve this problem is to utilize the split() method. This method breaks the string into substrings based on a delimiter (i.e., a specific substring).
my_string = "hello python world, I'm a beginner" result = my_string.split("world", 1)[1]
In the code above:
- split("world", 1) divides the string at the first occurrence of "world". The 1 argument specifies that we want to limit the split to a single occurrence.
- [1] selects the second substring, which contains the text after "world".
Therefore, the variable result now holds the desired substring: ", I'm a beginner".
