i'm on ubuntu , have python2.7, (it came pre-installed) python3.4, (used before today) , python3.5, upgraded today, installed in parallel. work fine on own. however, want use pip install packages, , can't figure out how 3.5 installation because pip installs 2.7 , pip3 installs python 3.4 packages. for instance, have asyncio installed on 3.4, can't import 3.5. when pip3 install aysncio , tells me requirement satisfied. i'm bit of newbie, did snooping around install directories , couldn't find , i've googled no avail. i suppose can run pip through python until sorted out. ( https://docs.python.org/dev/installing/ ) a quick googling seems indicate indeed bug. try , report back: python3.4 -m pip --version python3.5 -m pip --version if report different versions guess you're go. run python3.5 -m pip install package instead of pip3 install package install 3.5 packages.

i learning oracle pl/sql. want know loop best fetching data cursor. , please tell me when should use loop best performance. i rather avoid using explicit cursor , use cursor loop . for example, begin in (select column_list table ) loop <do something> end loop; end; / remember, loop row-by-row a.k.a. slow-by-slow . also, there reason why cursor loop better on explicit cursor. in recent oracle versions, optimized in better way doing bulk collect limit 100 internally. but, it's not bulk collecting , dealing operations subsequently on array have fetched incrementally. further improve performance using forall statement along bulk collect . imo, if possible, in pure sql . because, sql , pl/sql 2 different engines. procedural code handled pl/sql engine while sql handled sql statement executor, or sql engine. there overhead associated each context switch between 2 engines. so, if possible avoid context switching doing in pure sql.
