'python zipfile multiple files
i am having problems with python and zipfile, namely: I can't add a second file to my zip. here is my code, if you need more, I'll be glad to provide it.
def zipDir(fn_source, fn_destinationFolder):
''' fn_destinationFolder = folder to zip
fn_source = destination path for the zip
'''
fn_zipfileName = os.path.join(os.path.dirname(os.path.basename(fn_source)),fn_destinationFolder)+'.zip'
with zipfile.ZipFile(fn_zipfileName, 'w') as fn_zipfile:
for csvFile in os.listdir(fn_destinationFolder):
# fn_zipfile.write(csvFile)
if csvFile.endswith('.csv'):
try:
# fn_zipfile.write(os.path.join(fn_destinationFolder,csvFile)) ## write the whole filestructure to zip, '/home/uname/.../xyz.zip'
fn_zipfile.write(csvFile) ## write only the file to zip 'xyz.zip'
except IOError:
None
print('did not add',csvFile,'to',fn_zipfile)
fn_zipfile.printdir()
return fn_zipfileName
in the "test" dir, I have 2 files: "example.csv" and "example1.csv" this results in the following error:
python3.5 removing_the_header_from_CSV.py --from test --to zip
Removed headers from example.csv
Removed headers from example1.csv
did not add example1.csv to <zipfile.ZipFile filename='/home/xxx/repos/automate_the_boring_stuff/14_csv_files_and_json_data/NEW_test_2016-05-22_12-19-23.zip' mode='w'>
File Name Modified Size
example.csv 2016-05-20 17:12:19 191
zipfile can be found at /home/xxx/repos/automate_the_boring_stuff/14_csv_files_and_json_data/NEW_test_2016-05-22_12-19-23.zip
if I only use the "fn_zipfile.write(csvFile)", I get this extra info:
python3.5 removing_the_header_from_CSV.py --from test --to zip
Removed headers from example.csv
Removed headers from example1.csv
Traceback (most recent call last):
File "removing_the_header_from_CSV.py", line 169, in <module>
main()
File "removing_the_header_from_CSV.py", line 156, in main
zipfileName = zipDir(source, destinationFolder)
File "removing_the_header_from_CSV.py", line 112, in zipDir
fn_zipfile.write(csvFile)
File "/usr/lib/python3.5/zipfile.py", line 1433, in write
st = os.stat(filename)
FileNotFoundError: [Errno 2] No such file or directory: 'example1.csv'
I tried this with different files and always the same result except when I only have 1 file in my test dir. Then, all works as expected.

One of your problems is that you are listing the contents of some remote source directory, for some reason called fn_destinationFolder, to get the file names, filtering for .csv - lower case only and then telling the zipfile to add the filename. This is like saying to someone, who is in London, get a yellow cab at the junction of 1st and Main after checking that those streets exist in New York and that there is a cab rank there.
Make sure that you pass fn_zipfile.write
the full path to the input file - you can also override the name inside of the zip file, e.g.:
fn_zipfile.write(os.path.join(fn_destinationFolder, csvFile), csvFile)
