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.

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=" ")
