Question

所以基本上我需要创建一个标记为[0,1,2,3,4,5,10,25,100]的缓冲区列表。然后我需要在（0.75和4.75）+3之间创建随机数。现在我需要打印“缓冲3拍摄和平均 x 秒”之类的内容。 x 将是生成的随机数。每个缓冲区必须有自己的随机数

def main():
    buffer= [0,1,2,3,4,5,10,25,100]
    time= random.uniform(0.75,4.75)+3
    sum=0
    for i in range (1, 500):
        sum = sum + time;
        average= sum/1500
        for buffer in range(0,1,2,3,4,5,10,25,100):
           print("For Buffer",buffer,",the average time is",average,".")

[解决]

#Lab 1 using python.
Import random  #Importing random number generator.
def main():
    buffers= [0,1,2,3,4,5,10,25,100]; #Defining the buffers using list.
    for buffer in buffers:
        sum=0;

        for i in range (1, 500): # Create a loop which will create random number and increment 500 times.
            time= (random.uniform (0.75,4.75))+3
            sum = sum + time

        average= sum/500; #Finding the average of each buffers random numbers.

        print("For Buffer",buffer,",the average time is",average,"."); #Print the output.

Answer 1

您只需要更改它，以便在for循环中完成平均计算。

buffer= [0,1,2,3,4,5,10,25,100]
    for buffer in range(0,1,2,3,4,5,10,25,100):
          sum=0
          for i in range (1, 500):
             time= random.uniform(0.75,4.75)+3
             sum = sum + time;
             average= sum/1500
          print("For Buffer",buffer,",the average time is",average,".")

Answer 2

您可以使用字典将每个缓冲区与其平均值相关联，并使用缓冲区直接作为键，并将值与其平均值相关联。

def main():
    buffer= [0,1,2,3,4,5,10,25,100]
    time= random.uniform(0.75,4.75)+3
    sum=0
    dict_of_buffers = {}
    for i in range (1, 500):
        sum = sum + time;
        average= sum/1500
        for buffer in range(0,1,2,3,4,5,10,25,100):
            print("For Buffer",buffer,",the average time is",average,".")
            dict_of_buffers[buffer] = average

Python：创建随机数后，如何将这些数字与我所做的列表相关联
