group_list = ['Jhon', 'James', 'Rita', 'Ruth']
names = ['issah', 'ruth', 'kane']
for name in names:
    if name.title() not in group_list:
        group_list.append(name).title()

Answer 1

number_of_names_added = 0
group_list = ['Jhon', 'James', 'Rita', 'Ruth']
names = ['issah', 'ruth', 'kane']
for name in names:
    if name.title() not in group_list:
        group_list.append(name.title())  # Correction here
        number_of_names_added += 1
print(f'{number_of_names_added} name(s) added to group_list')
