11. Split String Elements to Multiple Lines

Write a NumPy program to split the element of a given array to multiple lines.

Sample Solution:-

Python Code:

# Importing necessary library
import numpy as np

# Creating a NumPy array containing a single string with newline characters
x = np.array(['Python\nExercises, Practice, Solution'], dtype=np.str)

# Displaying the original array
print("Original Array:")
print(x)

# Splitting the single string in the array by line breaks
r = np.char.splitlines(x)

# Displaying the result after splitting the string by line breaks
print(r)

Sample Input:

['Python\\Exercises, Practice, Solution']

Sample Input:

(['Python\Exercises, Practice, Solution'], dtype=np.str)

Sample Output:

[list(['Python\\Exercises, Practice, Solution'])]

Explanation:

In the above exercise –

x = np.array(['Python\Exercises, Practice, Solution'], dtype=np.str): This line creates a numpy array x containing a single string. The string includes backslashes and commas.

r = np.char.splitlines(x): This code uses the numpy function np.char.splitlines() to split the string in x into substrings based on newline characters, and stores the result in the variable r.

For more Practice: Solve these Related Problems:

Create a function that splits a long string into multiple lines at each comma or semicolon using np.char.splitlines.
Implement a solution that replaces a specific delimiter with a newline character and then splits the string accordingly.
Test the function on an array of strings containing various delimiters to ensure all line breaks are captured.
Combine the multiple-line split with a stripping operation to remove extraneous whitespace from each line.
