Python: Create a list reflecting the modified run-length encoding
Python List: Exercise - 76 with Solution
Write a Python program to create a list reflecting the modified run-length encoding from a given list of integers or a given list of characters.
Sample Solution:
Python Code:
from itertools import groupby
def modified_encode(alist):
def ctr_ele(el):
if len(el)>1: return [len(el), el[0]]
else: return el[0]
return [ctr_ele(list(group)) for key, group in groupby(alist)]
n_list = [1,1,2,3,4,4,5, 1]
print("Original list:")
print(n_list)
print("\nList reflecting the modified run-length encoding from the said list:")
print(modified_encode(n_list))
n_list = 'aabcddddadnss'
print("\nOriginal String:")
print(n_list)
print("\nList reflecting the modified run-length encoding from the said string:")
print(modified_encode(n_list))
Sample Output:
Original list: [1, 1, 2, 3, 4, 4, 5, 1] List reflecting the modified run-length encoding from the said list: [[2, 1], 2, 3, [2, 4], 5, 1] Original String: aabcddddadnss List reflecting the modified run-length encoding from the said string: [[2, 'a'], 'b', 'c', [4, 'd'], 'a', 'd', 'n', [2, 's']]
