在没有数组帮助的情况下，如何检查 3/5 值是否相同？

Question

Good day folks.I'm new to coding and currently trying to figure out if I have a set of 5 die. die1, die2, die3, die4, die5 and I want to check if 3/5 have the same value. Is it possible without the help of an array? :)

Answer 1

Without array:

s = (die1==1)+(die2==1)+(die3==1)+(die4==1)+(die5==1)
if s >= 3:
    print('yes')
else:
    s = (die1==2)+(die2==2)+(die3==2)+(die4==2)+(die5==2)
    if s >= 3:
        print('yes')
    else:
        s = (die1==3)+(die2==3)+(die3==3)+(die4==3)+(die5==3)
        if s >= 3:
            print('yes')
        else:
            s = (die1==4)+(die2==4)+(die3==4)+(die4==4)+(die5==4)
            if s >= 3:
                print('yes')
            else:
                s = (die1==5)+(die2==5)+(die3==5)+(die4==5)+(die5==5)
                if s >= 3:
                    print('yes')
                else:
                    s = (die1==6)+(die2==6)+(die3==6)+(die4==6)+(die5==6)
                    if s >= 3:
                        print('yes')
                    else:
                        print('no')

Editing my post since I found a better solution:

dice = (10**die1 + 10**die2 + 10**die3 + 10**die4 + 10**die5) // 10

print(dice % 10 >= 3 or dice // 10 % 10 >= 3 or dice // 100 % 10 >= 3 or 
      dice // 1000 % 10 >= 3 or dice // 10000 % 10 >= 3 or dice // 100000 % 10 >= 3)

I know it would be faster to do a loop or explicit string / integer search for a digit >= 3, but in this case implicit array looping is possible:-)

Answer 2

Certainly. Use collections.Counter :

from collections import Counter

d1 = 1
d2 = 3
d3 = 4
d4 = 3
d5 = 3

counter = Counter([d1, d2, d3, d4, d5])
roll, count = counter.most_common()[0]

if count >= 3:
    print('At least 3 out of 5 values are the same.')

Strictly speaking, this does make use of a list (which I think is what you mean; an array is something else entirely), so it depends on what exactly your restriction means. You could always change it to a tuple ...

Answer 3

Quick update. Thanks for all the fast answer folks. Fount my answer in another forum: Counting repeated characters in a string in Python Here's how I did mine: diceValues = str(die1), str(die2), str(die3), str(die4), str(die5) print(diceValues)

for item in diceValues: count = diceValues.count(item) print(count)
