How to make a easily readable python code?

I’m program python code and this is my dataset. like below code, I want modify the dataframe.

I know the code is simple and hardcoding.

I want to program the code more simple and highly readble code. ex) for loop

enter image description here

data('move1') = np.where(data('move1_day') == 1, 
                 (data('move1'))+12,                         
                 data('move1'))

data('move2') = np.where(data('move2_day') == 1, 
                 (data('move2'))+12,                         
                 data('move2'))

data('move3') = np.where(data('move3_day') == 1, 
                 (data('move3'))+12,                         
                 data('move3'))

data('move4') = np.where(data('move4_day') == 1, 
                 (data('move4'))+12,                         
                 data('move4'))

data('move5') = np.where(data('move5_day') == 1,
                (data('move5'))+12,
                data('move5'))

data('move6') = np.where(data('move6_day') == 1,
                (data('move6'))+12,
                data('move6'))
