How to Extract Text After a Specific Substring in Python?

Extracting Strings after Specific Substrings

Obtaining substring fragments after a given target string poses a common challenge in programming. For instance, consider the need to extract the text following the word "world" from the string:

my_string="hello python world, I'm a beginner"

Solution: Utilize String Splitting

One straightforward approach involves splitting the string based on the target substring. This can be achieved using the split() method. The syntax is as follows:

string_variable.split(substring, maxsplit)

where:

• string_variable is the input string to split
• substring is the target string to split on
• maxsplit (optional) specifies the maximum number of splits

In our case, we can split my_string on "world" with a splitting limit of 1:

my_string="hello python world, I'm a beginner"
print(my_string.split("world", 1)[1])

This operation creates a list of two strings: one containing the portion before the target, and the other the desired substring following the target. By accessing the second item in the list (since Python uses zero-based indexing), we obtain the desired result:

", I'm a beginner"

This method provides a simple and efficient way to extract specific substrings from a string, regardless of its length or complexity.
