Hi,
NB - I'm the original poster here -
https://groups.google.com/d/topic/comp.lang.python/WUuRLEXJP4E/discussion -
however, that post seems to have diverted, and I suspect my original question
was poorly worded.
I have several Python scripts that use similar functions.
Currently, these functions are duplicated in each script.
These functions wrap things like connecting to databases, reading in config
files, writing to CSV etc.
I'd like to pull them out, and move them to a common module for all the scripts
to import.
Originally, I thought I'd create a package, and have it all work:
my_package
__init__.py
common/
my_functions.py
script1/
__init__.py
config.yaml
script1.py
script2/
__init__.py
config.yaml
script2.py
However, there apparently isn't an easy way to have script1.py and script2.py
import from common/my_functions.py.
So my new question is - what is the idiomatic way to structure this in Python,
and easily share common functions between the scripts?
Ideally, I'd like to avoid having everything in a single directory - i.e.
script1.py should be in it's own directory, as it has it's own config and other
auxiliary files. However, if this is a bad idea, let me know.
Also, say I have a class in script1.py, and I want it pull in a common method
as well. For example, I want multiples classes to have the following method:
def gzip_csv_file(self):
self.gzip_filename = '%s.gz' % self.output_csv
with open(self.output_csv, 'rb') as uncompressed:
with gzip.open(self.gzip_filename, 'wb') as compressed:
compressed.writelines(uncompressed)
self.logger.debug('Compressed to %s GZIP file.' %
humansize(os.path.getsize(self.gzip_filename)))
How could I share this? Mixins? Or is there something better?
Cheers,
Victor
