j: i32
i: i32
for i in range(5):
    j = i
    print("j: ", j)

Something like this doesn't give us the expected output on main . It appears that the code is calling the visit_stmt function of the SymbolTableVisitor, but the visit_For function is only defined in the BodyVisitor. Hence an empty visit_For function in the SymbolTableVisitor class should do the job. Once this is done , we have the correct output

j:  0
j:  1
j:  2
j:  3
j:  4
