Question

我正在生成x轴值，时间形式为1到23，v值是多个客户端。我希望将这两个列表作为字典加入，但是我使用linspace()生成了x的浮点值。

time_values = np.linspace(1,23,23) # print from 1,2...23
number_of_clients = [] # create empty list that will hold number of clients
        for i in range(1,24,1):
            rand_value =  random.randint(1,20) # generate number of clients
            number_of_clients.append(rand_value)


    data = dict(zip(time_values,number_of_clients))
    print data

输出

{1.0：12,2.0：11,3.0：3,4.0：19,5.0：12,6.0：12,7.0：5,8.0：13,9.0：15,10.0：3,11.0：15,12.0： 20,13.0：5,14.0：3,15.0：18,16.0：12,17.0：5,18.0：6,19.0：8,20.0：16,21.0：19,22.0：1,23.0：16}

如何将1.0转换为1等等。我尝试了int(time_vlaues)，但它没有效果

尝试使用astype方法将numpy float数组转换为int数组：

time_values = np.linspace(1,23,23) # print from 1,2...23
number_of_clients = [] # create empty list that will hold number of clients
for i in range(1,24,1):
    rand_value =  random.randint(1,20) # generate number of clients
    number_of_clients.append(rand_value)


data = dict(zip(time_values.astype(int),number_of_clients))
print(data)

或

time_values = np.linspace(1,23,23,dtype='int') # print from 1,2...23
number_of_clients = [] # create empty list that will hold number of clients
for i in range(1,24,1):
    rand_value =  random.randint(1,20) # generate number of clients
    number_of_clients.append(rand_value)


data = dict(zip(time_values,number_of_clients))
print(data)

输出：

{1: 17, 2: 6, 3: 8, 4: 3, 5: 12, 6: 11, 7: 18, 8: 1, 9: 8, 10: 1, 11: 17, 12: 2, 13: 5, 14: 6, 15: 1, 16: 8, 17: 19, 18: 2, 19: 13, 20: 15, 21: 16, 22: 17, 23: 14}

linspace（）生成一个浮点值，但是int是必需的
