This tutorial is aimed at Python programmers who want to learn how to replace the character ‘N’ with a newline in Python. This task is common while dealing with large datasets or file manipulations.
Python, being an easy-to-understand yet powerful programming language, makes this task straightforward with its built-in replace() function, which is a method of the string class.
Step 1: Create a String
Firstly, we need to have a string that contains the ‘N’ character, which we want to replace with a newline. Below, we create a string “PythonNProgramming” as an example.

# Python Code text = "PythonNProgramming" |
Step 2: Use the replace() function
The replace() function in Python is used to replace occurrences of a particular character (or substring) with another. Its syntax is string.replace(old, new), where ‘old’ is the character you want to replace and ‘new’ is the character you want to replace it with.

# Python Code new_text = text.replace('N', '\n') |
Here we are replacing ‘N’ with the newline character \n.
Step 3: Print the new string
After replacing ‘N’ with a newline, you can print the new string to see the replaced output. The newline character \n produces a line break in the output.

# Python Code print(new_text) |
The Output will be:

# Python Code text = "PythonNProgramming" new_text = text.replace('N', '\n') print(new_text) |
Conclusion
Python’s built-in method replace() makes it extremely easy to replace any character or sequence of characters within a string. In this tutorial, we used it to replace ‘N’ with ‘\n’ newline character.
This is especially useful when dealing with large textual data, where replacements of patterns/characters are commonly required. So, keep coding and make the most out of Python’s built-in functions.
