i have a database

```
database=['3456734567','qqqqgtcgagagagctacgagaqqqqgtcgagagagctacgagaqqqqgtcgagagagctacgaga']

```

and I want to extract the repeated string as
'34567'
'qqqqgtcgagagagctacgaga'

therefore I use the code as followings:

```
def string(s):
    return re.search(r'(.+?)\1+', s).group(1)

print string(data[0]) 
print string(data[1])  

```

however it only output '34567' and 'q'

please tell me how to edit and then get the result 'qqqqgtcgagagagctacgaga'
