i use numpy command line , have remember apply recurrent settings, example setting output formatting: np.set_printoptions(threshold=np.nan, precision=3, suppress=true, linewidth=180) is there global numpy config file automatically executed new python shell or during import can execute this? if not, there elegant way achieve effect? i not aware of such configuration file numpy (for matplotlib example have the matplotlibrc file ). but, workaround, can set environment variable pythonstartup pointing python script whatever want everytime python section starts. in case use import numpy np , import matplotlib.pyplot plt on... saving small amount of "overhead" everytime want try on python. example on windows: set pythonstartup=c:\users\yourlogin\somewhere\startup.py example on linux: export pythonstartup=/usr/local/bin/startup.py you should set once using "control panel\system", example, on windows.

(java) 18 answers abstract class { abstract void method(); } class b extends { b() { } void method() { } } class c extends b { c() { } } when instantiate class c in main, automatically calls constructor b (parent class). normal or doing wrong? there nothing wrong, there implicit call super constructor. you haven't written constructor class c default constructor provided compiler be. c(){ super(); } if default constructor provided, there call super() . in case, c extends b constructor of b gets called. if not class other class, default extends object class. object class constructor called.

c++ - Initialization List Vs Static Const Initializing -

what faster when creating 100+ newobjs: //initialization list struct struct_obj { ...tonsofvars struct_obj() : tonsofvars(init) {} } or: //static const constructed, call copy constructor(?) static const struct_obj defaultstruct_obj = { tonsofvars(init) }; struct_obj newobj = defaultstruct_obj tonsofvars imply multiple different variables (from pod structs/classes) i assume static const, since calling copy constructor (meaning 1 op?) vs calling each initializer in initalization list? although common response "profile it", doing not give me explanation why faster. it depends on types in tonsofvars . i assume static const, since calling copy constructor (meaning 1 op?) vs calling each initializer in initalization list? it calling 1 copy constructor struct_obj , still needs call copy constructor each field. if pod data, there no difference @ all. however, in types default constructors may faster (or slower) copy constructors, make
