in this post , guido van rossum says function call may expensive, not understand why nor how expensive can be. how delay adds code simple function call , why? a function call requires current execution frame suspended, , new frame created , pushed on stack. relatively expensive, compared many other operations. you can measure exact time required timeit module: >>> import timeit >>> def f(): pass ... >>> timeit.timeit(f) 0.15175890922546387 that's 1/6th of second million calls empty function; you'd compare time required whatever thinking of putting in function; 0.15 second need taken account, if performance issue.

in verilog, can assign string vector like: wire [39:0] hello; assign hello = "hello"; in vhdl, i'm having difficulty finding method this: signal hello : out std_logic_vector (39 downto 0); ... hello <= "hello"; i've been using: hello <= x"65_68_6c_6c_6f"; which unclear , time consuming large strings. i've looked @ textio package , the txt_util package , neither seem clear on how interpret string , convert std_logic. is there simple method of assigning ascii codes std_logic in vhdl? here's minimal example: library ieee; use ieee.std_logic_1164.all; entity test port( ctrl : in std_logic; stdout : out std_logic_vector (39 downto 0) ); end entity; architecture rtl of test signal temp : std_logic_vector (39 downto 0); begin stdout <= temp; process(ctrl) begin if (ctrl = '0') temp <= "hello"; -- x"68_65_6c_6c_6f"; else temp <=...

i have class alert creates popup type feature in pygame. want draw text popup body, doesn't work. tested rendering text , saving bitmap. black box. thing kills me, class (button) below works perfectly, , gets called instance of class alert! @ least know can't parameter passing issue guess class alert(object): def __init__(self,msg,x,y,dim_x,dim_y,the_game,screen,size=16): self.x = x self.y = y self.e_x = x+dim_x self.e_y = y+dim_y self.dim_x=dim_x self.real_dim_y=dim_y self.dim_y = dim_y self.the_game = the_game self.the_screen = screen self.font = the_game.font.font(none,size) self.bitmap = the_game.surface((dim_x,dim_y)) self.bitmap.fill(alert_body) print "msg: %r" % msg if((msg!=none) , (msg!=false)): text = self.font.render(msg,1,(0,0,0)) the_game.image.save(text,"text-test.bmp") self.bitmap.blit(...

lets have array 4 different types of elements. 1 1 2 3 1 2 2 3 3 4 4 1. i want find longest subinterval results in equal number of each elements , largest total number of elements. in case, 1 1 2 3 1 2 2 3 3 because results in 3 twos, 3 threes, , 3 ones. i believe sort of modified dynamic programming, or requires prefix sums not sure. can give me insight on how start? #!/usr/bin/env python #the demo data set = [1,1,2,3,1,2,2,3,3,4,4,1] #function map counts of values in set def map(x): ret = {} v in x: if v not in ret.keys(): ret.update({v:0}) ret[v] += 1 return ret #function check if counts in map same def checkmap(x): val = none k,v in x.items(): if val != none , v != val: return false else: val=v return true #determine initial counts counts = map(set) #now step end inde...

type pt_int = int type pt_string = string data polytype = pt_int int | pt_string string given function f, how write function lifts polytype? (just trying understand lifting) your polytype equivalent either int string . in case haven't seen either before: data either b = left | right b so have function like liftp :: (either int string -> a) -> polytype -> liftp f poly = case poly of pt_int -> f (left i) pt_string s -> f (right s) polytype contains either int or string , can lift functions defined on both int , string . that said, don't think you're after. term "lifting" used in context of polymorphic data types [a] , maybe a , (->) a or in general type f a f :: * -> * . in these cases, given function g :: -> b , want new function [a] -> [b] , maybe -> maybe b or in general f -> f b . fmap functor . class functor f fmap :: (a -> b) -> (f -> f b) but polytype monomorphi...

i trying make pic1 master , pic2 slave through spi communication. want send command pic1 (master) pic2 (slave), have something. want establish spi communication pic2 (slave) digital potentiometer (mcp4241) through spi communication well. work ? to illustrate : pic1 sends 'a' ---- > pic2 reads pic2 ---- > establishes connection digital pot(mcp4241) pic2 ---- > sends data digital pot so there spi communications between pic1 , pic2, pic2 , digital pot, don't know if going work since need use same pins. 2 pics, using pic16f690. i hope question clear , please if won't work how should fix it? thanks! first of all, easy life, i'd recommend using pic 2 spi ports pic2. however, if sure want use 1 spi port master , slave thing keep in mind don't want both pics try drive serial line @ same time. may have write tris registers make port tristate go high-z disabling spi peripheral. if put series resistors in things less ...
