Python：在创建随机数字后，我如何将这些数字与我制作的列表相关联

所以基本上我需要创建一个标记为[0,1,2,3,4,5,10,25,100 ]。然后我需要在（0.75到4.75）+3之间创建随机数。现在我需要打印一些东西，如“缓冲区3和平均值为x秒”。 x将是生成的随机数。每个缓冲区必须有它自己的随机数Python：在创建随机数字后，我如何将这些数字与我制作的列表相关联

def main(): 
    buffer= [0,1,2,3,4,5,10,25,100] 
    time= random.uniform(0.75,4.75)+3 
    sum=0 
    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.

你只需要改变它，你的平均计算在你的循环中完成。

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,".")

您可以将每个缓冲区与其平均值相关联，使用一个字典使用缓冲区直接作为键和值的平均值。

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
