9 Feb 2018 Using buffer modules(StringIO, BytesIO, cStringIO) we can impersonate string or bytes data like a file.These buffer modules help us to mimic our local_path is the local file path where the downloaded file or files will be stored. if you specify a file-like object such as a StringIO for the local_path argument. may contain shell-style wildcards, as understood by the Python glob module. The StringIO and cStringIO Modules You can implement file-like objects by writing Python classes that supply the methods you need. If all you want is for data to Odoo11: Python 3 expects string, not bytes, when writing to file-like objects. 2/2/18, 12:26 I did changed import StringIO from io, but no luck.
