如何在两个字符串中找到“看不见”的差异

def find_invisible_difference(str1, str2):
    differences = []
    length = min(len(str1), len(str2))
    
    for i in range(length):
        if str1[i] != str2[i]:
            differences.append(i)
    
    if len(str1) > len(str2):
        differences.extend(range(length, len(str1)))
    elif len(str1) < len(str2):
        differences.extend(range(length, len(str2)))
    
    return differences

# 示例用法
str1 = "Hello World"
str2 = "Hello Wxrld"
differences = find_invisible_difference(str1, str2)
print("差异的位置：", differences)
