Python 多线程 掷骰子 问题。（萌新）

import random
from pygal import Bar
from multiprocessing import Process, Manager,freeze_support


class 骰子类():
def __init__(self, 骰子面数=6):
self.骰子面数 = 骰子面数

def 掷骰子结果方法(self):
return random.randint(1,self.骰子面数)


骰子实例 = 骰子类()
结果列表 = Manager().list()
def 掷骰子函数(次数):
for 投掷次数 in range(次数):
结果列表.append(骰子实例.掷骰子结果方法())

#掷骰子函数(100)
if __name__ == '__main__':
freeze_support()
骰子进程批量 = Pool(10)
for i in range(11):
骰子进程批量.apply_async(掷骰子函数,args=(100,))
骰子进程批量.close()
骰子进程批量.join()
print(结果列表)
每面出现次数字典 = Counter(结果列表)
print(每面出现次数字典)

An attempt has been made to start a new process before the

This probably means that you are not using fork to start your
child processes and you have forgotten to use the proper idiom
in the main module:

if __name__ == '__main__':
freeze_support()
...

The "freeze_support()" line can be omitted if the program
is not going to be frozen to produce an executable.


emmm 环境在 windows 下。
