Cutting the same (quite reasonable) corners as you, I've got it down 212
characters:
t,f,a,o,n='True','False','and','or','not'
l=[" Boolean Operators\n"+"-"*24]
for x in [(l,p,r)for p in(a,o)for l in(t,f)for r in(t,f)]+[(n,t),(n,f)]:x='
'.join(x);l+=[x[0].upper()+x[1:]+" is "+str(eval(x))]
for i in 12,9,5,0:l.insert(i,'')
print('\n'.join(l))
Reproducing the original string exactly the best I've managed is 260:
t,f,a,o,n='True','False','and','or','not'
l=[" Boolean Operators\n"+"-"*24]
for x in [(l,p,r)for p in(a,o)for l in(t,f)for r in(t,f)]+[(n,t),(n,f)]:x='
'.join(x);l+=[x[0].upper()+x[1:]+" is "+str(eval(x))]
for i in 12,9,5,0:l.insert(i,'')
print('\n'.join(l))
