Operation confirmed with python 3.6.0 on Windows

For those who want to read a Google Drive spreadsheet file with python, but don't know what Google's sample is doing, just want to read it.

Former story https://developers.google.com/sheets/api/quickstart/python First of all, please do your best until STEP2.

Then it is the program part of STEP3

#You can do various things using values
print(values)

Please add your own error handling _ (: 3 ”∠) _

If you want to read all the sheets in a spreadsheet, it's useful to get SHEET_TAB from a list of metadata sheets instead of fixed values.

#Sheet loading
#Get the service together
service = apiclient.discovery.build('sheets', 'v4', http=http, discoveryServiceUrl='https://sheets.googleapis.com/$discovery/rest?version=v4')

#Get the name of the sheet before reading values
sheet_meta = service.spreadsheets().get(spreadsheetId=SHEET_ID).execute()
for sheet in sheet_meta.get('sheets', ''):
    #Get sheet name
    SHEET_TAB = sheet.get("properties", {}).get("title", 0)

    #Here too(SHEET just before_TAB overwriting)
    values = service.spreadsheets().values().get(spreadsheetId=SHEET_ID, range=SHEET_TAB+'!'+RANGE).execute().get('values', [])

    #You can do various things using values
    print(values)
