Answer 1

you can use:

df['dummy'] = df.y.apply(lambda x:  1 if  x == 'Accepted' else 0)

if you want to use a for loop:

new_dummy_data = []

for value in df.y.values:
    if value == 'Accepted':
        new_dummy_data.append(1)
    else:
        new_dummy_data.append(0)

df['dummy'] = new_dummy_data
