NumPy: Split the element of a given array to multiple lines
NumPy String: Exercise-11 with Solution
Write a NumPy program to split the element of a given array to multiple lines.
import numpy as np x = np.array(['Python\Exercises, Practice, Solution'], dtype=np.str) print("Original Array:") print(x) r = np.char.splitlines(x) print(r)
['Python\\Exercises, Practice, Solution']
(['Python\Exercises, Practice, Solution'], dtype=np.str)
[list(['Python\\Exercises, Practice, Solution'])]

Python: Tips of the Day
Getting the last element of a list:
some_list[-1] is the shortest and most Pythonic.
In fact, you can do much more with this syntax. The some_list[-n] syntax gets the nth-to-last element. So some_list[-1] gets the last element, some_list[-2] gets the second to last, etc, all the way down to some_list[-len(some_list)], which gives you the first element.
You can also set list elements in this way. For instance:
>>> some_list = [1, 2, 3] >>> some_list[-1] = 5 # Set the last element >>> some_list[-2] = 3 # Set the second to last element >>> some_list [1, 3, 5]
Note that getting a list item by index will raise an IndexError if the expected item doesn't exist. This means that some_list[-1] will raise an exception if some_list is empty, because an empty list can't have a last element.
