Compress the String in python – HackerRank Solution

In this task, we would like for you to appreciate the usefulness of the groupby() function of itertools . To read more about this function, Check this out .
You are given a string S. Suppose a character ‘c’ occurs consecutively X times in the string. Replace these consecutive occurrences of the character ‘c’ with (X,c)
in the string.
For a better understanding of the problem, check the explanation.


Input Format :

A single line of input consisting of the string S.

Output Format :

A single line of output consisting of the modified string.

Constraints :

All the characters of S denote integers between 0 and 9.

  • 1 <= | S | <= 10^4

Sample Input :

1222311

Sample Output :

(1, 1) (3, 2) (1, 3) (2, 1)

Explanation :

First, the character 1 occurs only once. It is replaced by (1, 1). Then the character 2 occurs three times, and it is replaced by (3, 2) and so on.
Also, note the single space within each compression and between the compressions.
