关于python-----languages.keys()

Question

favorite_languages = {
'jen': 'python',
'sarah': 'c',
'edward': 'ruby',
'phil': 'python',
friends = ['phil', 'sarah']
for name in favorite_languages.keys():
print(name.title())

    if name in friends:
        print(" Hi " + name.title() +
            ". I see your favorite languages is " +
            favorite_languages[name].title() + "!")


            以上得出的答案是" Hi , Sarah, I see your favorite language is c!"

            为什么没有显示出 " Hi ,Phil I see your favorite language is python!"
            只显示出了Sarah的那一句？？
