How to Truncate a Long String after Given Size in Python? Last Updated : 26 Nov, 2024 Summarize Comments Improve Suggest changes Share Like Article Like Report Truncating a long string to a specified size in Python can be achieved using several methods, such as slicing, string methods, and specialized libraries. Each approach is suitable for different scenarios based on your requirements. Let’s explore how to efficiently truncate strings.Using String Slicing (Fixed-length truncation)The simplest way to truncate a string is by using slicing ([:]). This method is fast and intuitive for fixed-size truncation. Python # Truncate using slicing s1 = "Welcome to Python programming!" # Truncate to the first 10 characters s2 = s1[:10] print(s2) OutputWelcome to String slicing extracts the characters up to the specified index, making it ideal for quick truncation tasks.If you want to indicate truncation, you can append an ellipsis (...) or other markers after slicing. Python # Truncate with ellipsis s1 = "Welcome to Python programming!" n = 10 s2 = s1[:n] + "..." if len(s1) > n else s1 print(s2) # output: Welcome to... Let's look at another method to truncate a long string after given size in python:Using textwrap.shorten for Whole-word truncationThe textwrap module provides a built-in shorten method that truncates a string intelligently, ensuring whole words are preserved. Python import textwrap # Truncate using textwrap.shorten s1 = "Welcome to Python programming!" s2 = textwrap.shorten(s1, width=15, placeholder="...") print(s2) OutputWelcome to... The shorten method avoids breaking words by truncating to the nearest whole word and adding a placeholder if necessary.
