比较两个字符串中的每个字符并递增: Python

def increase_characters(str1, str2):
    # 确保两个字符串长度相同
    if len(str1) != len(str2):
        return "Error: 两个字符串长度不一致！"

    # 逐个字符比较并递增
    result = ""
    for i in range(len(str1)):
        char1 = str1[i]
        char2 = str2[i]
        
        # 比较并递增字符
        if char1 > char2:
            result += chr(ord(char1) + 1)
        elif char1 < char2:
            result += chr(ord(char2) + 1)
        else:
            result += char1

    return result

str1 = "abc"
str2 = "def"
result = increase_characters(str1, str2)
print(result)
