Python Program that extract words starting with Vowel From A list

When you need to extract words starting with vowels from a list, Python offers several approaches. You can use iteration with the startswith() method, list comprehensions, or the filter() function.

Using Loop with startswith() Method

This approach uses a flag to check if each word starts with any vowel ?

words = ["abc", "phy", "and", "okay", "educate", "learn", "code"]
print("The list is:")
print(words)

result = []
vowels = "aeiou"
print("The vowels are:", vowels)

for word in words:
    flag = False
    for vowel in vowels:
        if word.startswith(vowel):
            flag = True
            break
    if flag:
        result.append(word)

print("The result is:")
print(result)

The list is:
['abc', 'phy', 'and', 'okay', 'educate', 'learn', 'code']
The vowels are: aeiou
The result is:
['abc', 'and', 'okay', 'educate']

Using List Comprehension

A more concise approach using list comprehension with the any() function ?

words = ["abc", "phy", "and", "okay", "educate", "learn", "code"]
vowels = "aeiou"

result = [word for word in words if any(word.startswith(vowel) for vowel in vowels)]
print("Words starting with vowels:", result)

Words starting with vowels: ['abc', 'and', 'okay', 'educate']

Using filter() Function

Using filter() with a lambda function to check vowel conditions ?

words = ["abc", "phy", "and", "okay", "educate", "learn", "code"]
vowels = "aeiouAEIOU"  # Include uppercase vowels

result = list(filter(lambda word: word[0].lower() in vowels, words))
print("Words starting with vowels:", result)

Words starting with vowels: ['abc', 'and', 'okay', 'educate']

Comparison

How It Works

• Loop method: Uses a flag variable to track if any vowel matches the first character
• List comprehension: Uses any() to check if the word starts with any vowel
• Filter method: Checks if the first character (converted to lowercase) exists in the vowels string

Conclusion

List comprehension with any() provides the most readable and efficient solution. Use the loop method for learning purposes and filter() for functional programming approaches.
