比较两个字符串中的单个字符

def compare_strings(a, b):
    result = True
    if len(a) != len(b):
        print('string lengths do not match!')
    for i, (x, y) in enumerate(zip(a, b)):
        if x != y:
            print(f'char miss-match {x, y} in element {i}')
            result = False
    if result:
        print('strings match!')
    return result
print(compare_strings("canada", "japan"))

Output:

string lengths do not match!
char miss-match ('c', 'j') in element 0
char miss-match ('n', 'p') in element 2
char miss-match ('d', 'n') in element 4
False
