How to convert tuple type to int on python?

What you have there is a tuple inside a tuple. So you want the first item of the outer tuple, which is u_data[0]: the innermost tuple. And then you want the first item of that, which is u_data[0][0]. That's a float, so to get an integer, you want to wrap the whole thing in int(), leading us to:

int(u_data[0][0])
