import re

def remove_consonants_and_print_vowels(lst):
    vowels = ['a', 'e', 'i', 'o', 'u']
    vowel_list = []

    for char in lst:
        if re.match(r'[aeiou]', char, re.IGNORECASE):
            vowel_list.append(char)

    print(vowel_list)

# 示例调用
my_list = ['a', 'b', 'c', 'd', 'e', 'f', 'g']
remove_consonants_and_print_vowels(my_list)
