pandas calculate distance between coordinates

x1 = df1.x_coord.values x2 = df2.x_coord.values y1 = df1.y_coord.values y2 = df2.y_coord.values We can then calculate the squared distances, d2 = np.square( x2 - x1 ) + np.square( y2 - y1 ) distances = np.sqrt( d2 ) The distances array is the required distance per row.
