ahoj vsem

zkousim naprogramovat funkci:

h=(64*x**8)-(128*x**6)+(16*y**6)+(80*x**4)-(24*y**4)-(16*x**2)+(9*y**2)

kde x je z intervalu <-1,1> a y=<-1,1>. Jde o to ze vypisem programu by mel byt obrazek ktery bude obsahovat 37 radku a v kazdem radku bude 73 znaku. Ty znaky jsou + a -. Kdyz vyjde funkce h dosazeni za x  a y z daneho intervalu zaporna vytiskne se - a kdyz vyjde 0 nebo kladna tak plus...

tady je kdyz tak ten vystup-obrazek

muj navrh je tento:

import os
import math
import sys
import numpy as np

for x in np.arange (-1,1,2.0/37.0):
    for y in np.arange (-1,1,2.0/73.0):  
        h=(64*x**8)-(128*x**6)+(16*y**6)+(80*x**4)-(24*y**4)-(16*x**2)+(9*y**2)

        if h<0:
           sys.stdout.write('-')
        elif h>=0:
           sys.stdout.write('+')

ten modul np.arange umoznuje rodelit interval tedy muj <-1,1> pomoci desetinneho cisla 2.0/37.0

kdyz ten skrip spustim tak se mi zacnou vypisovat + a - ....ale problem je v tom ze po 73 znacich v radku to pokracuje dal coz nechci...chtel bych aby po 73 znacich to preskocilo na dalsi radku...

ma nekdo nejake reseni? dekuji za odpovedi

Jednoduse. Vzdycky kdyz skonci ten druhy for cyklus, tak vypis znak do konzole pro novy radek. Nevim jak to je v pythonu, ale asi:

sys.stdout.write('\n')

dik za odpoved ale to nebude to prave orechove...zkusil jsem to v ruznych kombinacich a nefunguje to

jooooo uz to mam ...dekuji TI ...mas pravdu... Byla to jen zalezitost sys.stdout.write('\n') jak jsi napsal a spravneho potukani na tabelator...

posilam skript:

import os
import math
import sys
import numpy as np

for x in np.arange (-1,1,2.0/37.0):
    for y in np.arange (-1,1+2.0/73.0,2.0/73.0):
            h=(64*x**8)-(128*x**6)+(16*y**6)+(80*x**4)-(24*y**4)-(16*x**2)+(9*y**2)

            if h<0:
               sys.stdout.write('-')
            elif h>=0:
               sys.stdout.write('+')

    sys.stdout.write('\n')

dekuji mnohokrat
