android & sqlite - Query a single item -


I'm calling a method to see if there is a value within the database or not. 

  string [] column = {table.NAME}; String [] selections = {name}; Cursor cursor = db.query (table.TABLE_NAME, column, table. Name + "=?", Selection ARGS, blank, empty, empty, blank); Int index = cursor.getColumnIndex (table.ID);

Whether the name exists or does not always index -1?

Whether the name exists or does not always index -1?

Because you have not included the column in table.ID .

getColumnIndex

Python Equivalent for matlab cart2pol and pol2cart -

I would like to use pol2cart and cart2pol for two functions in MATLAB. Is there an equivalent Python Function? Or if we can define work? For example, I tried to use the CeMatePactor function, but it only accepts one argument, I have 2 arguments to cross the polar and REC function. P> I have tried to use this function for cart2pol: def cart2pol (x, y): theta = atan2 (y, x) rho = Sqrt (x ** 2 + y ** 2) returns (theta, ro) thanks
