Question

我在字典中有特定的值，从高到低排序，但最多可以有一千或更多的值。如果数字介于1-10之间并且给出图形的输出与dict中的前1-10个最高值，那么如何进行用户输入。因此，如果他们输入3，它将绘制3个最高值等...感谢高级

frequency1 = Counter({'1':100,'2':400,'3':200,'4':300,})



response1 = input("How many top domains from source? Enter a number between 1-10: ")

if response1 == "1":        
    if len(frequency1) >= 1:

        print("\nTop 1 most is:")

下面的代码将创建字典中值的排序列表，然后绘制最大数字的相应图表，具体取决于用户输入。

import numpy as np
import matplotlib.pyplot as plt

d = {'1':100,'2':400,'3':200,'4':300,}

vals = sorted(d.values(), reverse=True)

response = input("How many top domains from source? Enter a number between 1-10: ")

if response > 0 and response < len(vals)+1:

    y = vals[:response]

    print ("\nTop %i most are:" %response)
    print (y)

    x = np.arange(1,len(y)+1,1)

    fig, ax = plt.subplots()

    ax.bar(x,y,align='center', width=0.2, color = 'm')

    ax.set_xticks(x)
    ax.set_xticklabels(x)
    ax.set_xlabel("This graph shows amount of protocols used")
    ax.set_ylabel("Number of times used")
    ax.grid('on')   
else:
    print ("\nThere are not enough domains for this top amount.")

plt.show()

例如，如果用户在代码中输入3，则会生成以下图表并输出：

Top 3 most are:
[400, 300, 200]

如何根据用户输入将字典中的值从最高到最低绘制
