要使用 `for` 循环和 `break` 找出列表中第一个首字母为 "a" 的单词,你可以按照以下步骤编写代码:
```python
wordList = ["cherry", "lemon", "apricot", "blueberry", "durian", "grape", "apple"]
# 初始化一个变量来存储找到的第一个以 "a" 开头的单词,初始值设为 None
first_word_starting_with_a = None
# 遍历 wordList
for word in wordList:
# 检查单词的首字母是否为 'a'
if word.lower() == 'a':
# 如果找到,设置 first_word_starting_with_a 为当前单词并退出循环
first_word_starting_with_a = word
break
# 输出结果
if first_word_starting_with_a is not None:
print("第一个以 'a' 开头的单词是:", first_word_starting_with_a)
else:
print("列表中没有单词以 'a' 开头。")
```
运行这段代码后,它会找到第一个以 "a" 开头的单词并打印出来。
