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

    # 示例一:小写变大写
    msg_1 = 'my name is sophia'
    print('小写变大写后是:'+msg_1.upper())

    # 示例二:大写变小写
    msg_2 = 'MY NAME IS SOPHIA'
    print('大写变大写后是:'+msg_2.lower())

    # 示例三:大写变小写,小写变大写,生成镜像字符串;利用字符串的内置方法来解决
    def change_msg_3(s):
    s = s.swapcase()# 互换大小写
    in_tab = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'
    out_tab = 'ZYXWVUTSRQPONMLKJIHGFEDCBAzyxwvutsrqponmlkjihgfedcba'
    reflect = s.maketrans(in_tab, out_tab)# 建立翻译表
    s = s.translate(reflect)# 根据翻译表进行翻译
    return s
    if name == 'main':
    s = 'MynameisSOPHIA'
    new_s = change_msg_3(s)
    print("转换之前的字符串:", s)
    print("转换之后的字符串:", new_s)

    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')
    s_4=s_3.replace('A','Z')
    s_5=s_4.replace('D','W')
    s_6=s_5.replace('F','U')
    s_7=s_6.replace('d','w')
    s_8=s_7.replace('a','z')
    print("替换后:",s_8)
