python - is it ok to use files inside pip packages without installing them -


i working on project , have cloned repository github.
after first compile realized project cloned has dependencies , in requirements.txt file.

i know have install these packages, dont want cause on windows development environment , after finishing project going publish ubuntu production environment , dont want take hassle of double installation.

i have 2 options:

  1. using virtualenv , installing packages inside it

  2. downloading packages , use them direct way using import foldername

i wanna avoid first option cause have less control on project , problem gets bigger , bigger if example inside project's virtualenv , wanted run project's main.py file own virtualenv , etc... moving virtualenv windows (bat files) linux (bash / sh files) seems ugly me , directs me approaches choose better avoid.

the second option choice. example need use future package. scenario downloading package using pip download future , when done extracting tar.gz file, inside src folder can see future package folder, , use import future_package.src.future without touching else.

enter image description here

aside os.path problems (which assume take care of):

is practice?

i not running setup.py preventing installation. can cause problems?

is there better approach involves less work (like second one) or better 1 mentioned first approach?

update 1: have extracted future , certifi packages part of requirements of project , used them direct way , working in particular case.

just wondering if guys can code. it works serving images not pdf brochure. in advance func main(){ http.handlefunc("/", func(w http.responsewriter, r *http.request){ filename := "/var/www/filedipenser/brochure.pdf" streampdfbytes, err := ioutil.readfile( filename ) if err != nil { fmt.println(err) os.exit(1) } b := bytes.newbuffer(streampdfbytes) w.header().set("content-type", "application/pdf") if _, err := b.writeto(w); err != nil { fmt.fprintf(w, "%s", err) } w.write([]byte("pdf generated")) }) err := http.listenandserve(":4111", nil) if err != nil { log.fatal("listenandserve: ", err) fmt.println(err) } } the code bit inefficient appears working. however, pdf viewers might sensitive extraneous output adding end of http response stream...

python - Best design pattern for collection of objects -

i have following architecture: +-----------------+ | collection | | | | | | | | | +-----------------+ | ^ | | create() | | | | v | getitem(b) +------------+ | | item | | | | | | +------+ | | +------------+ a class managing collection of items, creates items. , these items may need other items collection. the actual code in python, , collection passes parameter created item . see it, bad practice. improvement can see pass few functions of collection needed item , instead of whole instance. for example: class collection: getitem(self, id): ... createitem(self, id): item = item(id, self) # <-- pass self ... class item: __init__(self, id, col): ... col.getite...
