在 Python 中检查两个字符串是否包含相同的字母和数字

from string import ascii_letters, digits
def compare_alphanumeric(first, second):
    for character in first:
        if character in ascii_letters + digits and character not in second:
            return False
    return True
str1 = 'ABCD'
str2 = 'ACDB'
print(compare_alphanumeric(str1, str2))
str1 = 'A45BCD'
str2 = 'ACD59894B'
print(compare_alphanumeric(str1, str2))
str1 = 'A45BCD'
str2 = 'XYZ9887'
print(compare_alphanumeric(str1, str2))

Output:

True
True
False
