eval() in python

[Xah Lee]

is it possible to eval a string like the following?

m='''
i0=[0,1]
i1=[2,3]
i2=[4,'a']

h0=[]
for j0 in i0:
  h1=[]
  for j1 in i1:
    h2=[]
    for j2 in i2:
      h2.append(f(j0,j1,j2))
    h1.append( h2[:] )
  h0.append( h1[:] )
return h0'''

perhaps i'm tired, but why can't i run:

t='m=3'
print eval(t)

the doc seems to suggest that eval is only for expressions... it says
uses exec for statements, but i don't seem to see a exec function?
