NameError: name 'maketrans' is not defined, pythonchallenge

[cirfu]

im doing the python challenge and well, i solved this problem with
ruby :)
phrase = "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.kyicrpyl q() gq pcamkkclbcb. lmu ynnjw ml rfc
spj."
puts phrase .tr('A-XY-Za-xy-z','C-ZA-Bc-za-b')

the answer says to use maketrans but i cant get it to work:

>>pat = maketrans('A-XY-Za-xy-z', 'C-ZA-Bc-za-b')

Traceback (most recent call last):
File "<pyshell#1 >", line 1, in <module>
pat = maketrans('A-XY-Za-xy-z', 'C-ZA-Bc-za-b')
NameError: name 'maketrans' is not defined

>>"hej tjena tjenixen".maket rans('A-XY-Za-xy-z', 'C-ZA-Bc-za-b')

Traceback (most recent call last):
File "<pyshell#0 >", line 1, in <module>
"hej ditt fetto".maketran s('A-XY-Za-xy-z', 'C-ZA-Bc-za-b')
AttributeError: 'str' object has no attribute 'maketrans'

pattern = maketrans('A-XY-Za-xy-z', 'C-ZA-Bc-za-b')
pattern = maketrans('A-Za-z', 'C-Bc-b')
none works....

table = string.maketran s(string.ascii_ lowercase,
string.ascii_lo wercase[2:]+string.ascii_l owercase[:2])
print string.translat e(text,table)

maketrans doesn't work like that, you would need something like this:

sfrom = string.uppercas e + string.lowercas e
sto = string.uppercas e[2:] + string.uppercas e[:2] +
string.lowercas e[2:] + string.lowercas e[:2]
table = string.maketran s(sfrom, sto)

print string.translat e(phrase, table)
