Google custom search next page

My proposition is to add next parameter. In current software you have q, cx and num. You could try add start=10 and then execute the code.

res = service.cse().list(
    q='lectures',
    cx='013036536707430787589:_pqjad5hr1a',
    num=10,
    start=10,
).execute()

First result page URL doesn't have start parameter. Second page has URL which contains start=10 parameter. Third page has URL which contains start=20 ...

Good luck

The response object contains a 'nextPage' dictionary. You can use this to determine the start index of the next request. Like so:

res = service.cse().list(
     q='lectures',
     cx='013036536707430787589:_pqjad5hr1a',
     num=10, #Valid values are integers between 1 and 10, inclusive.
).execute() 

next_response = service.cse().list(
     q='lectures',
     cx='013036536707430787589:_pqjad5hr1a',
     num=10,
     start=res['queries']['nextPage'][0]['startIndex'],
).execute()
