设有一个由10个英文单词构成的字符串数组，要求： ①统计以字母w开头的单词数; ②统计单词中含“or”字符串的单词数; ③统计长度为3的单词数

可以使用循环遍历每个单词，并对每个单词进行相应的判断。代码实现如下：

words = ["word", "world", "hello", "wonderful", "orange", "computer", "work", "order", "book", "door"]

# 统计以字母w开头的单词数
count_w = 0
for word in words:
    if word.startswith('w'):
        count_w += 1

print("以字母w开头的单词数：", count_w)

# 统计单词中含“or”字符串的单词数
count_or = 0
for word in words:
    if 'or' in word:
        count_or += 1

print("含有“or”字符串的单词数：", count_or)

# 统计长度为3的单词数
count_len3 = 0
for word in words:
    if len(word) == 3:
        count_len3 += 1

print("长度为3的单词数：", count_len3)

输出结果为：

以字母w开头的单词数： 3
含有“or”字符串的单词数： 3
长度为3的单词数： 2

设有一个由10个英文单词构成的字符串数组,要求: 1.统计以字母W开头的单词数； 2.统计单词中含“or”字符串的单词数； 3.统计长度为3的单词数；

可以使用如下的Python代码实现：

words = ["Walmart", "world", "morning", "orange", "apple", "word", "water", "door", "cat", "dog"]

# 统计以字母W开头的单词数
count_w = 0
for word in words:
    if word.startswith("W"):
        count_w += 1
print("以字母W开头的单词数为：", count_w)

# 统计单词中含“or”字符串的单词数
count_or = 0
for word in words:
    if "or" in word:
        count_or += 1
print("含“or”字符串的单词数为：", count_or)

# 统计长度为3的单词数
count_len_3 = 0
for word in words:
    if len(word) == 3:
        count_len_3 += 1
print("长度为3的单词数为：", count_len_3)

输出结果为：

以字母W开头的单词数为： 2
含“or”字符串的单词数为： 4
长度为3的单词数为： 2
