Solve the following python programming problem given the following code:
def test_default_args(self) : 
    def func(self, foo, bar = 2) : 
        return (foo - bar) 
code = py2js (func) 
    lines = [line for line in code.split ('
') if line] 
    assert (lines [1] == 'func = function (foo, bar) {') 
    assert ('2' in code) 
    assert (evaljs ((code + 'func(2)')) == '0') 
    assert (evaljs ((func + 'func(4, 3)')) == '1') 
    assert (evaljs ((code + 'func(0, 0)')) == '0') 

    
    

    Fix the buggy line: assert (evaljs ((func + 'func(4, 3)')) == '1')
assistant
#Here is Python program to fix the buggy line: assert (evaljs ((func + 'func(4, 3)')) == '1')
.

assert (evaljs ((code + 'func(4, 3)')) == '1')
