return results[0].description causes error list index out of range

The title alone is self explanatory.
Here is the code if anyone is interested:

``
from googleapi import google
def search(query):
    num_page = 1
    results = google.search(query, num_page)
    return results[1].description
def convert(string):
    li = list(string.split('.'))
    return li

userin = input('?')
info = search(userin)
print(convert(info)[0])
