i'm playing around bitwise operators more comfortable using them. the problem i'm having since python has infinite width integers, it's difficult see actual results of operations. >>> bin(0b00000001 & 0b11110111) 0b1 i'd see 0b00000001 instead. is there way experiment these operators fixed-size integers in python? use format() function: print(format(0b00000001 & 0b11110111, '#010b')) output 0b00000001 the string parameter format() function specifies format of output. # makes output include 0b prefix, , 10 indicates entire output should 10 characters. 0 preceding 10 enforces 0 left-padding in 10 output characters. can remove hash if want remove 0b prefix.

so express best practices page, among others, states 1 should use debug module debugging , winston logging app activity in production. why 1 not use winston all? ...and if using both how 1 decide goes in winston debug vs debug's debug? express best practices / debug module / winston module it's not big deal library use log/debug, many express applications use neither winston nor debug. debug has convenience features makes easier use on using winston debugging. use winston, , write own wrapper around debug() method in order replicate exact functionality of debug module. if use both, use debug module log messages used strictly developing , diagnosing bugs, , use winston log messages file/database/service while application in production.
