Python Program to Split joined consecutive similar characters

When it is required to split the joined consecutive characters that are similar in nature, the ‘groupby’ method and the ‘join’ method are used.

Example

Below is a demonstration of the same

from itertools import groupby

my_string = 'pppyyytthhhhhhhoooooonnn'
print("The string is :")
print(my_string)

my_result = ["".join(grp) for elem, grp in groupby(my_string)]

print("The result is :")
print(my_result)

Output

The original string is :
pppyyytthhhhhhhooonnn
The resultant split string is :
['ppp', 'yyy', 'tt', 'hhhhhhh', 'ooo', 'nnn']

Explanation

  • The required packages are imported into the environment.

  • A string is defined and it is displayed on the console.

  • The string is iterated over and it is sorted using the ‘groupby’ method.

  • It is converted to a list, and is assigned to a variable.

  • This is displayed as output on the console.
