[pythonchallenge1]string.maketrans

我得代码：

>>> arr=[]
>>>temp=''
>>> for chs in s.split():
	for ch in chs:
		temp+=chr(ord(ch)+2)
	arr.append(temp)
	temp=''

然后再替换特殊字符

 试图用一行代码写出来，没写成功。

答案1：

>>> import string
>>> text = """g fmnc wms bgblr rpylqjyrc gr zw fylb. rfyrq ufyr
... amknsrcpq ypc dmp. bmgle gr gl zw fylb gq glcddgagclr ylb rfyr'q
 ... ufw rfgq rcvr gq qm jmle. sqgle qrpgle.kyicrpylq() gq pcamkkclbcb.
... lmu ynnjw ml rfc spj."""
>>> table = string.maketrans(
...   string.ascii_lowercase,
...   string.ascii_lowercase[2:]+string.ascii_lowercase[:2])

for x in s:
	if ord(x)>=ord('a') and ord(x)<=ord('z'):
		o+=chr((ord(x)+2-ord('a'))%26+ord('a'))
	else:
		o+=x
print o
