ich bin neu hier im Forum, wollte aber trotzdem mal mein kleines Programm zeigen und ggf. Verbesserungsvorschlaege einnehmen. Also ohne weitere Verzoegerung, hier mein Code: (Dokumentation auf Englisch)
Code: Alles auswählen
year_start = day_start = day_target = month_target = month_start = year_target = 0
full_year_flag = False
#inputs
while day_start < 1 or day_start > 31:
day_start = input("insert beginning day ")
while month_start > 12 or month_start < 1:
month_start = input("insert beginning month ")

year_start = input("insert beginning year ")
while day_target < 1 or day_target > 31:
day_target = input("insert target day ")
while month_target > 12 or month_target < 1:
month_target = input("insert target month ")
while year_target <= year_start: #backward time count doesn't make sense, obviously.
#Same year counts won't work with the algorithm.
year_target = input("insert target year ") #problem occurs when you try to count
#time less than a year.
#year, month converter algorithm
if month_target > month_start:
years_distance = year_target - year_start # +(month_target-month_start)/12.0+(<something with days>), so the
# years won't round up
months_distance = 12 * years_distance + month_target - month_start #but then this has to change (would get
#simpler in fact)
elif month_target < month_start:
years_distance = (year_target - year_start) - 1
months_distance = (years_distance * 12) + (12 + (month_target - month_start))

#case 2) test purposes 3) convince about the corectness
#of the algorithm
#days converter algorithm (can get the +5 days accuracy with a month list implemented)
if day_target > day_start:

#them backwards to years and months

#simple secs/hours/mins, can get more accurate, but for it to have any
#meaning, the day algorithm has to improve
