Ooops, I accidentally hit 'send' on that other e-mail before I was done
with it.
I was just going to say that you forgot to include 'random'.
Also, here is the code with the changes I suggested.
I ran it on 1,2,3,4,5,6 for 80 tries and didn't win every time.
#code begins here.
import random
winnings=0
prizes = [0,0,1,4,15,450,1000000]
user_nums=[] # empty List for numbers
print "Kies je nummers tussen 0 en 46"
print
whereat=0
# when 6th number is inputted loop breaks
while whereat < 6:
num=raw_input("Voer "+str(whereat+1)+". Lotto nummer in: ")
# check that user inputted value is not smaller than 1 or bigger than 45
# and that it is not already in user_nums
try:
tmp = int(num)
if tmp >= 1 and tmp <= 45 and tmp not in user_nums:
user_nums.append(tmp)
whereat += 1
except ValueError:
pass
print '1 trekking kost U 1 euro inzet'
print
vDraws = input("Hoe vaak wil je in de lotto spelen met deze nummers? :>")
# Create dictionary for statiscal purposes later on :-)
d = {}
for x in range(1,46):
d[x] = 0
match=0
count=0
inzet=vDraws
while vDraws > 0:
x=random.sample(range(1,46), 6)# draws lottery from given range
for i in x:
d[i] += 1 #stores values in lottonumbers dictionary
for p in user_nums:
if p == i:
match+=1 # increase matching variable by one if its
right number
winnings += prizes[match]
match = 0
vDraws -= 1
# sorting dictionary by its values
items=d.items()
backitems=[ [v[1],v[0]] for v in items]
backitems.sort()
sortedlist=[ backitems[i][1] for i in range(0,len(backitems))]
print '\n\n'
saldo=winnings-inzet
print '\n'
print '-' * 80
if saldo > 0:
print 'U heeft', saldo, 'euro winst gemaakt!'
else:
print 'U heeft', saldo, ' euro verlies geleden!'
print 'U heeft in totaal gewonnen', winnings, 'euro.'
print 'Uw inzet was', inzet, 'euro'
print 'De 6 meest gevallen getallen waren:',
for x in sortedlist[0:6]: print x, #prints the 6 most drawn numbers
