I want to write a file. Based on the name of the file this may or may not be compressed with the gzip
module. Here is my code:
import gzip
filename = 'output.gz'
opener = gzip.open if filename.endswith('.gz') else open
with opener(filename, 'wb') as fd:
print('blah blah blah'.encode(), file=fd)
I'm opening the writable file in binary mode and encoding my string to be written. However I get the following error:
File "/usr/lib/python3.5/gzip.py", line 258, in write
data = memoryview(data)
TypeError: memoryview: a bytes-like object is required, not 'str'
Why is my object not a bytes? I get the same error if I open the file with 'w'
and skip the encoding step. I also get the same error if I remove the '.gz'
from the filename.
I'm using Python3.5 on Ubuntu 16.04
