favorite_languages = {
    'jen': ['python', 'ruby'],
    'sarah': 'c',
    'edward': ['ruby', 'go'],
    'phil': ['python', 'haskell'],
}
for name, languages in favorite_languages.items():
    if len(languages) >= 2 in favorite_languages:
        print(f"\n{name.title()}'s favorite  language's are:")
        for language in languages:
            print(language)
    else:
        print(f"\n{name.title()}'s favorite  language are:")
        for language in languages:
            print(language)

但这支队伍if被放行了。如果通过 查询字典值的长度print，它会打印2, 1, 2, 2。
