by the way, you can use below to format your code

```python


def foo(input_variable):
tmp = Variable(torch.zeros(input_variable.size()))
return torch.cat((input_variable, tmp), 1)



it will be formated like this
def foo(input_variable): 
     tmp = Variable(torch.zeros(input_variable.size())) 
     return torch.cat((input_variable, tmp), 1)

it’s  markdown sytanx
