def main():

    service = build("customsearch", "v1",
                 developerKey="")

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

    for value in res:
        #print value
        if 'items' in value:
            for results in res[value]:
                print results['formattedUrl'] 

if __name__ == '__main__':
  main()

响应对象包含一个“nextPage”字典。您可以使用它来确定下一个请求的开始索引。就像这样：

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()
