我是一个初学者,我的目标是编写一个名为count_vowels的函数,该函数接受表示单词的字符串参数,并返回单词中的元音数量。下面是我到目前为止要解释的代码: string = 'oboe' count = 0 if 'a' or 'A' in string1 if &#x 浏览24提问于2020-11-04得票数 1 回答已采纳 1回答 检查文本文件python中...

def vowels_count(s): count = 0 for chr in s: if chr in 'aeiouAEIOU': count += 1 return count print vowels_count('hello world') 输出结果: 字符串索引 字符串中每个字符都有一个索引值(下标),索引从0(前向)或-1(后向)开始 froward index 0 1 2 3 4 h e l l o backward index -5 ...

return [vowel for vowel in string if vowel in 'aeiou'] #list comprehension print("Vowels are:", get_vowels('This is some random string')) Output: Vowels are: ['i', 'i', 'o', 'e', 'a', 'o', 'i'] 3. 列表中的最大值或最小值 ...
没有__iter__方法,但Vowels实例是可迭代的,因为——作为后备——如果 Python 发现__getitem__方法,它会尝试通过调用从0开始的整数索引的方法来迭代对象。因为 Python 足够聪明以迭代Vowels实例,所以即使缺少__contains__方法,它也可以使in运算符正常工作:它会进行顺序扫描以检查项目是否存在。
▍90、使用itertools中的count计算元素的数量 from itertools import count my_vowels = ['a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U'] current_counter = count() string = "This is just a sentence." for i in string: if i in my_vowels: print(f"Current vowel: {i}...
