Python13 期字符串大考核!!!

请用自己目前所学实现字符串大写转小写,小写变大写,并且将字符串变为镜像字符串。例如:’A’变为’Z’,’b’变为’y
示范字符串:
”sdSdsfdAdsdsdfsfdsdASDSDFDSFa”字符串大写变小写 小写变大写,然后最后变为镜像字符串。

Python13 期 前来报道!!!

    a='sdSdsfdAdsdsdfsfdsdASDSDFDSFa'
    print (a.swapcase())
    # 字符串大小写转换
    a='sdSdsfdAdsdsdfsfdsdASDSDFDSFa'

    s += i
    print(s)
    # 镜像字符串

    s="sdSdsfdAdsdsdfsfdsdASDSDFDSFa"
    print(s.upper())
    print(s.lower())
    print(s.swapcase())

    print("替换前:",s)
    s_1=s.replace('s','h')
    s_2=s_1.replace('S','H')
    s_3=s_2.replace('f','u')
