Think functional! This is 257 characters:
def D(x,y,s):return s.replace(x,y)
print(D('1','True',D('0','False',D('&',' and ',D('|',' or ',D('!','Not
',D('=',' is ',D('!','Not ',""" Boolean Operators
------------------------
1&1=1
1&0=0
0&1=0
0&0=0
1|1=1
1|0=1
0|1=1
0|0=0
!1=0
!0=1"""))))))))
And applying the same idea twice I can get 255:
def D(x,y,s):return s.replace(x,y)
print(eval(D('"D','D("',D(',','","','''"D-,--,D1,True,D0,False,D&, and ,D|, or
,D!,Not ,D=, is ,D!,Not ,"" Boolean Operators
