Question

我是python和编程的新手。我正在尝试创建一个骰子模拟器，允许用户选择骰子有多少边以及掷骰子多少次。然后程序应该跟踪每个数字出现的次数并显示结果。

我已经做到这一点，随机数生成器将为每个卷生成一个随机数。但我无法弄清楚如何跟踪每个数字出现的次数并显示出来。请帮忙：

# dice simple

import random


x = input ("How many sides does you dice have?")
y = input ("How many times do you want to roll?")



for i in range (y):
    z = random.randint (1, x)

Answer 1

defaultdict非常适合：

from collections import defaultdict

d = defaultdict(int)
d[1] += 1
d[6] += 1
d[1] += 1

print(d)
defaultdict(<type 'int'>, {1: 2, 6: 1})

Answer 2

from collections import Counter
import sys
from random import randint

# Python 2/3 compatibility
if sys.hexversion >= 0x3000000:
    inp = input
    rng = range
else:
    inp = raw_input
    rng = xrange

def get_int(prompt):
    while True:
        try:
            return int(inp(prompt))
        except ValueError:
            pass

def main():
    sides = get_int("How many sides does your die have? ")
    times = get_int("How many times do you want to roll? ")
    results = Counter(randint(1, sides) for roll in rng(times))

if __name__=="__main__":
    main()

Answer 3

# dice simple

import random


x = input ("How many sides does you dice have?")
y = input ("How many times do you want to roll?")


for i in range (y):
    z = random.randint (1, x)
