问为什么遍历字典中的值，只打印最后一个？

favorite_languages = {

'jen': ['python','ruby'],

'sarah': ['c'],

'edward': ['ruby','go'],

'phil': ['python','haskell']

}

for name,languages in favorite_languages.items():

print(languages)

for language in languages:

print('\t'+language.title())

#输出结果

['python', 'ruby']

['c']

['ruby', 'go']

['python', 'haskell']

Python

Haskell
