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
a = 'sdSdsfdAdsdsdfsfdsdASDSDFDSFa'
first=''
for i in a:
if i.islower():
first = first + i.upper()
else:
first = first + i.lower()
last=''
for i in a:
if i.islower():
last=last+chr(219 - ord(i))
else:
last = last + chr(155 - ord(i))
print (first)
print(last)
c='sdSdsfdAdsdsdfsfdsdASDSDFDSFa'
print(c.swapcase())
