Description
下面是我自己写的代码，可以计算出每个单词的个数，但不知道怎么写按照从大到小排序了。
我看了其他人的代码基本上都是一步步出来的，看着代码能够理解，不过我希望能够使用下列字典推导式的代码一步写出来。请问在这个方法基础上怎么加入排序呢？
去掉符号、空格及将字母全部改成小写
text_a=text.replace(',','').replace('.','').replace('--','').replace('!','')
text_b=(text_a.lower()).split()
print(text_b)
在前一步基础上，使用字典统计各英文单词的个数
text_dict = {i:text_b.count(i) for i in text_b}
print(text_dict)
*停了好多个月重新开始学真是不容易啊，相当于从0再开始终于又有点回到入门的感觉了，这次哪怕进度慢一点也要坚持学到最后。给自己立个Flag，争取年底之前学完。
