In questo articolo mostrerò un “orologio parlante” programmato in Python, ovvero un programma che, simulando una voce tramite il programma espeak, “dice” ogni 15 minuti che ore sono.

import os
import time

while 1==1:
	if ("15" in time.strftime("%M")) or ("30" in time.strftime("%M")) or ("45" in time.strftime("%M")):
		if ("10" in time.strftime("%H")) or ("20" in time.strftime("%H")):
			os.system("echo sono le %s e %s | espeak -v it"% (time.strftime("%H"), time.strftime("%M")))
		elif (time.strftime("%H") == "0") or (time.strftime("%H") == "00"):
			os.system("echo e\' mezzanotte e %s | espeak -v it"% time.strftime("%M"))
		else:
			os.system("echo sono le %s e %s | espeak -v it"% (time.strftime("%H").replace("0", ""), time.strftime("%M")))
		time.sleep(890)
	if ("00" in time.strftime("%M")):
		if ("10" in time.strftime("%H")) or ("20" in time.strftime("%H")):
			os.system("echo sono le ore %s | espeak -v it"% time.strftime("%H"))
		elif (time.strftime("%H") == "0") or (time.strftime("%H") == "00"):
			os.system("echo e\' mezzanotte | espeak -v it")
		else:
			os.system("echo sono le ore %s | espeak -v it"% time.strftime("%H").replace("0", ""))
		time.sleep(890)
	time.sleep(1)

Ecco una calcolatrice programmata in python con interfaccia grafica generata da WxGlade, l’ho fatta tanto tempo fa quando ancora stavo iniziando a creare i miei primi programmi con un interfaccia grafica.
