python - Cannot connect to the Gmail API to run the quickstart guide -

i'm trying set email business relationship utilize gmail api, , wanted run quickstart guide google has on site, getting error:

0:289: execution error: file object wasn’t found. (-43)

the code launches web browser takes me 400 page error:

error: redirect_uri_mismatch

any suggestions?

i believe error means have not appropriately registered redirect uri in api console. if go api console respective project, under apis, should see client ids. along should list of redirect uris. if not see right redirect uri want response returned to, add together list.
