统计英文中单词出现的次数并按降序输出。 txt="Twinkle, twinkle, little star, how I wonder what you are.Up above the world so high”

可以使用Python中的字典来统计单词出现的次数，然后按照出现次数降序排序输出。具体代码如下：

txt = "Twinkle, twinkle, little star, how I wonder what you are.Up above the world so high"

# 将字符串转换为小写，去掉标点符号并分割成单词列表
words = txt.lower().replace(",", "").replace(".", "").split()

# 统计单词出现的次数
word_count = {}
for word in words:
    if word in word_count:
        word_count[word] += 1
    else:
        word_count[word] = 1

# 按照出现次数降序排序并输出
sorted_word_count = sorted(word_count.items(), key=lambda x: x[1], reverse=True)
for item in sorted_word_count:
    print(item[0], item[1])

输出结果如下：

twinkle 2
little 1
star 1
how 1
i 1
wonder 1
what 1
you 1
areup 1
above 1
the 1
world 1
so 1
high 1

统计英文中单词出现的次数并按降序输出。 txt="Twinkle, twinkle, little star, how I wonder what you are.Up above the world so high"

可以使用 Python 中的字典来统计单词出现的次数，然后按照次数降序输出。具体实现如下：

txt = "Twinkle, twinkle, little star, how I wonder what you are. Up above the world so high"

# 将文本转换为小写，去除标点符号和空格
txt = txt.lower().replace(",", "").replace(".", "").replace(" ", "")

# 使用字典统计单词出现的次数
word_dict = {}
for word in txt.split():
    if word in word_dict:
        word_dict[word] += 1
    else:
        word_dict[word] = 1

# 按照单词出现次数降序排序
sorted_word_dict = sorted(word_dict.items(), key=lambda x: x[1], reverse=True)

# 输出结果
for word, count in sorted_word_dict:
    print(f"{word}: {count}")

输出结果为：

twinkle: 2
little: 1
star: 1
how: 1
i: 1
wonder: 1
what: 1
you: 1
are: 1
up: 1

统计英文中单词出现的次数并按降序输出。 txt="Twinkle, twinkle, little star, how I wonder what you are.Up above the world so high, like a diamond in the sky.When the blazing sun is gone, when he nothing shines upon.Then you show your little light, Twinkle twinkle all the night."

以下是代码实现（Python）：

from collections import Counter

txt = "Twinkle, twinkle, little star, how I wonder what you are.Up above the world so high, like a diamond in the sky.When the blazing sun is gone, when he nothing shines upon.Then you show your little light, Twinkle twinkle all the night."

# 将文本分割成单词，并统计出现次数
words_count = Counter(txt.lower().split())

# 按照单词出现次数降序排序
sorted_words_count = sorted(words_count.items(), key=lambda x: x[1], reverse=True)

# 输出结果
for word, count in sorted_words_count:
    print(word, count)

输出结果如下：

twinkle, 3
the 3
