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 = ''
    for i in a:
    if i.islower():
    i = chr(219 - ord(i))
    s += i
    elif i.isupper():
    i = chr(155 - ord(i))
    s += i
    print(s)
    # 镜像字符串

    w='sdSdsfdAdsdsdfsfdsdASDSDFDSFa'
    w1=w.swapcase()
    print('大小写转换后的字符串:',w1)
    new_w=''
    for i in w:
    if i.islower():
    i = chr(219-ord(i))
    new_w +=i
    elif i.isupper():
    i = chr(155 - ord(i))
    new_w +=i
    print('镜像字符串是:',new_w)
