  1. If stavek #o ceni... price = int(raw_input("What price? ")) if price == 100: # če je cena enaka 100 print “vzamem!" # vzamem else: if price > 500: # če je cena več kot 500 print “ni šans!" else: if price > 200: print “Ali se bi pogajala?" else: print “to pa ni cena!"

  2. If in SYS Primer ko je izhod iz zanke predčasen, oziroma pogoj ni izpolnjen za izvršitev jedra zanke import sys # kako uidemo iz zanke print “Tukaj začnemo" j = 5 #j dobi vrednost 5 if j > 10: # če je j večji od 10 print "This is never printed“ #nikoli stiskano else: sys.exit() #izhod iz zanke!!!!

  3. Meniji in if menu = """ Izberi lik (1-3): 1) Kvadrat 2) Pravokotnik 3) Trikotnik pravokotni """ shape = int(raw_input(menu)) if shape == 1: length = float(raw_input(“Dolžina: ")) #vpraša za stranico print “Ploščina kvadrata = ", length ** 2 elif shape == 2: length = float(raw_input(" Dolžina: ")) width = float(raw_input(“Širina: ")) print “Ploščina pravokotnika = ", length * width elif shape == 3: length = float(raw_input(“stranica a: ")) width = float(raw_input(“stranica b: ")) print “ploščina = ", length * width/2 else: print “poskusi ponovno, napaka"

  4. Še malo dodelan meni angleški

  5. For stavek

  6. Še for

  7. While

  8. Še os SYS

  9. Moduli 1

  10. Moduli 2

  11. Funkcije in Time

  12. Delo z datotekami

  13. Popravljeno delo z datoteko # izboljšana varianta # Odpremo datoteko za branje(r) inp = open("menu.txt","r") # iteriramo(ponavljamo) po datoteki in izpisujemo vsako vrsto for line in inp: print line.rstrip()#poreže posebne znake in jih ne tiska # ne pozabimo zapreti datoteke inp.close()

  14. Kopiranje datotek # Naredimo kopijo datoteke MENU.TXT v MENU.BAK # odpremo datoteki tako za branje kot pisanje) inp = open("menu.txt","r") outp = open("menu.bak","w") # beremo datoteko in pišemo v drugo for line in inp: outp.write(line) print "1 file copied..." # Ne pozabimo zapreti datotek inp.close() outp.close()

  15. Meni_datoteke_2_date import time # Create daily menu based on MENU.TXT inp = open("menu.txt","r") # First open the files to read(r) and write(w) outp = open("menu.prn","w") today = time.localtime(time.time()) # Create todays date string print today#izpis oblike datuma v pythonu theDate = time.strftime("%A %B %d", today) print theDate#izpis v “pravi obliki” datuma outp.write("Menu for %s\n\n" % theDate) # Add Banner text and a blank line for line in inp: # copy each line of menu.txt to new file outp.write(line) print "Menu created for %s..." % theDate inp.close() # Now close the files outp.close() Note that we use the time module to get todays date (time.time()) and convert it into a tuple of values (time.localtime()) which are then used by time.strftime() to produce a string which, when inserted into a title message using string formatting, looks like:

  16. Join in split besedilo
