编写代码统计英文中单词出现的次数并按降序输出

以下是Python代码实现：

text = "This is a sample text to test the word count program. This program should count the number of times each word appears in the text and display the result in descending order."

# 将所有单词转换为小写，以便进行比较
text = text.lower()

# 将文本分割为单词列表
words = text.split()

# 创建一个字典来存储每个单词出现的次数
word_count = {}

# 遍历单词列表并更新字典中的计数器
for word in words:
    if word not in word_count:
        word_count[word] = 1
    else:
        word_count[word] += 1

# 按降序输出单词计数
for word, count in sorted(word_count.items(), key=lambda x: x[1], reverse=True):
    print(word, count)

输出：
