In Python programming, extracting substrings from strings is a common task with various practical applications. Whether you’re parsing data, manipulating text, or performing data analysis, knowing how to efficiently extract substrings can greatly enhance your workflow.

In this article, we’ll explore simple yet powerful techniques to extract substrings from strings in Python.

Understanding Substring Extraction

Substrings are contiguous sequences of characters within a larger string. Extracting substrings involves retrieving specific portions of a string based on predefined criteria, such as starting and ending positions or specific patterns.

Using String Slicing for Substring Extraction

One of the most straightforward methods to extract substrings in Python is by using string slicing. With string slicing, you can specify the start and end indices to extract a substring:

# Define a string
text = "Python is amazing!"

# Extract a substring from index 7 to 9 (exclusive)
substring = text[7:10]
print(substring)  # Output: is
