iteration over non-sequence error in dictionary.keys()

[ruuram]

I'm new to Python. When I try to run the following program with
a3=DictAdder()
a3.add({1:1},{2:2}}
I get the "iteration over non-sequence" error.

class DictAdder:
def add(self, x, y):
dict={}
for k in x.keys(): dict[k]=x[k]
for k in y.keys(): dict[k]=y[k]
return dict

does anyone know what's wrong with the code? or I need to import some libraries? Thanks!

I don't see the problem.

When I run this:

class DictAdder:
    def add(self, x, y):
        dict={}
        for k in x.keys(): dict[k]=x[k]
        for k in y.keys(): dict[k]=y[k]
        return dict


a3=DictAdder()
print a3.add({1:1},{2:2})

I get this:

{1: 1, 2: 2}

I'm assuming the closing brace in your original post:

a3.add({1:1},{2:2}}
                  ^

is a typo.
