1、输入一个至少有10个英文单词构成的字符串，如：We love School of Computer Science and Engineering Yulin Normal University！要求： （1）统计以字母w开头的单词数； （2）统计单词中含“o”字符串的单词数； （3）统计长度为3的单词数。

好的，我来回答您的问题：

1. 统计以字母w开头的单词数：

sentence = "We love School of Computer Science and Engineering Yulin Normal University!"
words = sentence.split()  # 将句子分割成单词
count = 0
for word in words:
    if word.startswith('w') or word.startswith('W'):  # 判断单词是否以W或w开头
        count += 1
print("以W开头的单词数为：", count)

2. 统计单词中含“o”字符串的单词数：

sentence = "We love School of Computer Science and Engineering Yulin Normal University!"
words = sentence.split()  # 将句子分割成单词
count = 0
for word in words:
    if 'o' in word or 'O' in word:  # 判断单词中是否含有o或O
        count += 1
print("含有o的单词数为：", count)

3. 统计长度为3的单词数：

sentence = "We love School of Computer Science and Engineering Yulin Normal University!"
words = sentence.split()  # 将句子分割成单词
count = 0
for word in words:
    if len(word) == 3:  # 判断单词长度是否为3
        count += 1
print("长度为3的单词数为：", count)

希望能够帮到您！
