You can simply achieve that by:

gstr="aaabbccccffffdee"
last=gstr[0]
count=0
rstr=""
for i in gstr:
    if i==last:
        count=count+1
    elif i!=last:
        rstr=rstr+last+str(count)
        count=1
        last=i
rstr=rstr+last+str(count)
print ("Required string for given string {} after conversion is {}.".format(gstr,rstr))
