python创建字典，并且排序

word_dict = {}
#exclude_str = "，。！？、（）【】<>《》=：+-*—“”…"
for char in temp_pro:
    #for char in temp_pro[i]:
        #if char not in exclude_str:
            if char not in word_dict:  # 为了去掉空白
                word_dict[char] = 1
            else:
                word_dict[char] += 1
lstWords = sorted(word_dict.items(), key=lambda x: x[1], reverse=True)

#reverse=True这个是允许覆盖的意思
