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!!!

#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
