Question

我对Python很陌生并试图计算一堆随机数的平均值遇到了障碍。该程序的一般概述是它是一个模具滚动程序，它提示用户输入某个然后滚动，直到程序输出蛇眼。它还记录了双打的数量和获取蛇眼所需的时间。然后创建整个程序中为每个模具滚动的数字的平均值。这就是我迷失的地方。

编辑：我删除了原始代码并在Vasilis的答案中工作：

import random

while True:
    #prompts user for valid number
    user_s = int (input ("How many sides on your dice? "))
    if user_s < 3:
         print("That is not a valid size value, please enter a positive number")
    if user_s >= 3:
        break

print()
print("Thanks! Here we go...")
print()
double_count = 0 
roll_count = 0

sum1 = 0 # Used to calculate sum of die_1
sum2 = 0 # Used to calculate sum of die_2

while True:
    roll_count += 1
    die_1 = random.randint(1,user_s)   
    die_2 = random.randint (1,user_s)




    print(roll_count,".", " Die number 1 is ", die_1 , " and die number 2 is ", die_2,  ".", sep ="")
    if die_1 == die_2:
        double_count += 1
    if die_1 == 1 and die_2 == 1:
        break

    # Making sum
    sum1 = sum1 + die_1 
    sum2 = sum2 + die_2

print("You finally got snake eyes on try number", roll_count)
print("Along the way you rolled a double", double_count,"times")

print(die_1)
print(die_2)

# Integer divisions

avg_roll1 = sum1 // roll_count
avg_roll2 = sum2 // roll_count


print("The average roll for die 1 was", format(avg_roll1,".2f"))
print("The average roll for die 2 was", avg_roll2)

然而，正如他所指出的那样，它不会记录通过所有卷记录的所有数字，而是记录最后一个数字。任何帮助实现这一点将不胜感激。

谢谢！

如果你想看一下，我在代码中做了一些更改。我假设你想要将平均值计算为整数，尽管你可以改变它。您使用die_1和die_2作为简单的整数变量，因此它们只保留random.randint(1,user_s)生成的最后一个值：

import random

    '''Skipped input part'''

    print()
    print("Thanks! Here we go...")
    print()
    double_count = 0 
    roll_count = 0

    sum1 = 0 # Used to calculate sum of die_1
    sum2 = 0 # Used to calculate sum of die_2

    while True:
        roll_count += 1
        die_1 = random.randint(1,user_s)   
        die_2 = random.randint (1,user_s)

        print("DIE_1: ", die_1)
        print("DIE_2: ", die_2)


        print(roll_count,".", " Die number 1 is ", die_1 , " and die number 2 is ", die_2,  ".", sep ="")
        if die_1 == die_2:
            double_count += 1
        if die_1 == 1 and die_2 == 1:
            break

        # Making sum
        sum1 = sum1 + die_1 
        sum2 = sum2 + die_2

    print("You finally got snake eyes on try number", roll_count)
    print("Along the way you rolled a double", double_count,"times")

    print(die_1)
    print(die_2)

    # Integer divisions

    avg_roll1 = sum1 // roll_count
    avg_roll2 = sum2 // roll_count


    print("The average roll for die 1 was", avg_roll1)
    print("The average roll for die 2 was", avg_roll2)

自己动手。

将累加器变量=设置为模具辊。在这种情况下，sum1和sum2是变量。

# make all of the functions in the "random" module available to this program
import random

while True:
    #prompts user for valid number
    user_s = int (input ("How many sides on your dice? "))
    if user_s < 3:
         print("That is not a valid size value, please enter a positive number")
    if user_s >= 3:
        break

print()
print("Thanks! Here we go...")
print()
double_count = 0 
roll_count = 0

sum1 = 0 # Used to calculate sum of die_1
sum2 = 0 # Used to calculate sum of die_2

#while statement for die rolls
while True:
    roll_count += 1
    die_1 = random.randint(1,user_s)
    sum1 += die_1

    die_2 = random.randint (1,user_s)
    sum2 += die_2




    print(roll_count,".", " Die number 1 is ", die_1 , " and die number 2 is ", die_2,  ".", sep ="")
    if die_1 == die_2:
        double_count += 1
    if die_1 == 1 and die_2 == 1:
        break



print("You finally got snake eyes on try number", roll_count)
print("Along the way you rolled a double", double_count,"times")


# Integer divisions

avg_roll1 = sum1 / roll_count

avg_roll2 = sum2 / roll_count


print("The average roll for die 1 was", format(avg_roll1,".2f"))
print("The average roll for die 2 was", format(avg_roll2,".2f"))
