从列表中提取以元音开头的单词的Python程序

给定一个包含字符串元素的列表，以下程序提取以元音（a，e，i，o，u）开头的元素。

Input : test_list = [“all”, “love”, “get”, “educated”, “by”, “gfg”] 
Output : [‘all’, ‘educated’] 
Explanation : a, e are vowels, hence words extracted.
Input : test_list = [“all”, “love”, “get”, “educated”, “by”, “agfg”] 
Output : [‘all’, ‘educated’, ‘agfg’] 
Explanation : a, e, a are vowels, hence words extracted. 

方法一：使用startswith()和loop

在这里，我们检查每个单词，并在每个单词的第一个字母表上使用 startswith() 检查它是否以元音开头。迭代部分使用循环完成。

# initializing list
test_list = ["all", "love", "and", "get", "educated", "by", "gfg"]
  
# printing original list
print("The original list is : " + str(test_list))
  
res = []
vow = "aeiou"
for sub in test_list:
    flag = False
      
    # checking for begin char
    for ele in vow:
        if sub.startswith(ele):
            flag = True 
            break
    if flag:
        res.append(sub)
  
# printing result 
print("The extracted words : " + str(res))

输出：

The original list is : [‘all’, ‘love’, ‘and’, ‘get’, ‘educated’, ‘by’, ‘gfg’]
The extracted words : [‘all’, ‘and’, ‘educated’]

方法 2：使用any() 、 startswith()和循环

在此，我们使用 any() 检查元音，其余功能与上述方法类似。

# initializing list
test_list = ["all", "love", "and", "get", "educated", "by", "gfg"]
  
# printing original list
print("The original list is : " + str(test_list))
  
res = []
vow = "aeiou"
for sub in test_list:
      
    # check for vowel beginning
    flag = any(sub.startswith(ele) for ele in vow)
      
    if flag:
        res.append(sub)
  
# printing result 
print("The extracted words : " + str(res))

输出：

The original list is : [‘all’, ‘love’, ‘and’, ‘get’, ‘educated’, ‘by’, ‘gfg’]
The extracted words : [‘all’, ‘and’, ‘educated’]
