# HackerRank Compress the String! solution in python

In this Compress the string problem we need to develop a python program that can read a string as input and then we need to print the tuples containing the number of occurrence of integers on the output screen.

## Problem solution in Python 2 programming.

```from itertools import groupby
s=map(int,list(raw_input()))
l=[(sum(1 for i in g),k) for k,g in groupby(s)]
print ' '.join(map(str,l))```

## Problem solution in Python 3 programming.

```from itertools import groupby
for key, group in groupby(input()):
print('({}, {})'.format(len(list(group)), key), end=" ")```

### Problem solution in pypy programming.

```# Enter your code here. Read input from STDIN. Print output to STDOUT
from itertools import groupby

print " ".join(str((len(list(k)),int(i))) for i,k in groupby(raw_input()))```

### Problem solution in pypy3 programming.

```s=input()
prev_c=''
count=0
Out=()
for c in s :
if c == prev_c:
count+=1
else:
if prev_c!='':
print((count+1,int(prev_c)), end=" ")
prev_c=c
count=0
print((count+1,int(prev_c)),end=" ")```
