string - How to convert fileData from str to file type in Python? -

i've got file data read api base64 , converted regular file data using following:

base64filedata = attachmentobj.data['data'] filedata = base64.urlsafe_b64decode(base64filedata.encode('utf-8')) print type(filedata)  # prints out <type 'str'> 

since need file in binary further process it, can store , read out follows:

print type(filedata)  # prints out <type 'str'> open('thefile.pdf', 'w') f:     f.write(filedata) open('thefile.pdf', 'rb') f:     print type(f)  # prints out <type 'file'>, need. 

this works, seeing there no need store file, seems 1 of worst pieces of code i've ever seen.

does know how can convert initial filedata type 'file' without storing , reading out? tips welcome!

check out stringio / cstringio modules. present file interface existing buffer (string) in memory. let pass data library without writing temp file.

for example:

import stringio  ...  base64filedata = attachmentobj.data['data'] filedata = base64.urlsafe_b64decode(base64filedata.encode('utf-8'))  memoryfile = stringio.stringio(filedata)  somefunctionthatoperatesonfileobjects(memoryfile)
