SERVICE_ACCOUNT_FILE = 'keys.json'
SCOPES = ['https://www.googleapis.com/auth/spreadsheets']

creds = None
creds = service_account.Credentials.from_service_account_file(
    SERVICE_ACCOUNT_FILE, scopes=SCOPES)

# The ID and range of a sample spreadsheet.
SAMPLE_SPREADSHEET_ID = '1FL_OSVo82741728v_pMLlwiPx5fqS3WmoamM'

service = build('sheets', 'v4', credentials=creds)

#call the sheets API
sheet = service.spreadsheets()
result = sheet.values().get(spreadsheetId=SAMPLE_SPREADSHEET_ID,
                            range="blad1").execute()
values = result.get('values', [])

aoa = [['value1', '1/111/2020', 5220], ['value1', '1/111/2020', 5220], ['value1', '1/111/2020', 5220],
       ['value1', '1/111/2020', 5220], ['value1', '1/111/2020', 5220], ['value1', '1/111/2020', 5220],
       ['value1', '1/111/2020', 5220]]


request = sheet.values.append().update(spreadsheetId=SAMPLE_SPREADSHEET_ID,
                                range='blad1', valueInputOption='USER_ENTERED', body={'values':aoa}).execute()

print(values)

Answer 1

Replace:

request = sheet.values.append().update(spreadsheetId=SAMPLE_SPREADSHEET_ID,
                                range='blad1', valueInputOption='USER_ENTERED', body={'values':aoa}).execute()

With:

request = sheet.values().append(spreadsheetId=SAMPLE_SPREADSHEET_ID,
                                range='blad1', valueInputOption='USER_ENTERED', body={'values':aoa}).execute()
