Thanks for the replies, Dave and Joel. The reason I'm not just using the
time or datetime modules for a random date is because it's restricted to
1970-2038; I'm pulling dates from 1600-3099. Thanks a lot for the pointer
about the leap years, Dave, as well the class instances; just updated it and
it's all working now, and also included the rest of the code too w/ answer
verification and time tracking.
I want to start using this program to test myself for speed calculation
using Zeller's formula, it's pretty cool for determining the days of dates -
http://mathforum.org/dr/math/faq/faq.calendar.html
Because of the way variables C and D are split up from the year in the
formula, I split up the year for self.c and self.y.
------------------------
import random, time, datetime, calendar
class Date:
def __init__(self):
self.c = random.randint(16,30)
self.y = random.randint(0,99)
self.month = random.randint(1,12)
self.year = self.c*100 + self.y
apr = [4,6,9,11]
feb = [2]
notleap = [1700, 1800, 1900, 3000]
if self.month in feb:
if self.year%4 == 0:
if self.year in notleap:
self.k = random.randint(1,28)
else:
self.k = random.randint(1,29)
else:
self.k = random.randint(1,28)
elif self.month in apr:
self.k = random.randint(1,30)
else:
self.k = random.randint(1,31)
if self.month in [1,2]:
d = self.y - 1
m = self.month + 10
else:
d = self.y
m = self.month - 2
z = self.k + (13*m-1)/5 + d + d/4 + self.c/4 - 2*self.c
if z< 0:
r = (abs(z)/7)*7 + z + 7
else:
r = z%7
dict = { 0: 'Sunday', 1: 'Monday', 2: 'Tuesday', 3: 'Wednesday', 4:
'Thursday', 5: 'Friday', 6: 'Saturday' }
self.day = dict[r]
t1m = time.localtime().tm_min
t1s = time.localtime().tm_sec
t1 = t1m + t1s/100.0
n = 0
x = 0
while n< 10:
newdate = Date()
print '\n',calendar.month_name[newdate.month], newdate.k,',',
newdate.year,'=',
answer = raw_input()
if answer.capitalize() == newdate.day:
pass
else:
x += 1
n += 1
t2m = time.localtime().tm_min
t2s = time.localtime().tm_sec
t2 = t2m + t2s/100.0
td = t2 - t1
print '\n',x,'out of 10 wrong\nAvg time/question:',td/10,'\nTotal time:',td

(You top-posted your response, so your message is out of order)
I haven't tried to run your code, but there is at least one problem.
Your notleap list is very incomplete.
notleap = [1700, 1800, 1900, 2100, 2200, 2300, 2500, 2600, 2700, 2900, 3000]
I'm a little suspicious of your version of Zeller. I wouldn't think
that last term should have a 2* in it.
I'm not sure why you use a dictionary to calculate self.day. A list
would work just as well.
