Getting error while replacing the dataframe value using numpy

Question

I am new to python here I have a data-frame

id    values
1      100
2      200
3      3600
4      3654

Now, Here I am trying to replace the values using the following way

file_name = file_name.loc[file_name['values'] == 3654,file_name['values'] ,3600]

Here the values are like ,

if 3654 is then replace it with 3600 otherwise keep it as it is.

So, I am getting this error,

only integers, slices (`:`), ellipsis (`...`), numpy.newaxis (`None`) and integer or boolean arrays are valid indices

can any one help me with this ?
