python - 仅打印 dict 值

Question

我试图弄清楚为什么我的循环打印字典中的所有内容而不仅仅是值

films = {
"2005": ["Munich", "Steven Spielberg"], 
"2006": [["The Prestige", "Christopher Nolan"], ["The Departed", "Martin Scorsese"]]
}

    for year in movies:
        print (year)
        for x in films[year]:
            print (films[year])

我希望它像这样打印

2005
Munich, Steven Spielberg

2006
The prestige, Christopher Nolan
the Departed, Martin Scorsese

但是它的打印方式是这样的，带有括号和撇号

2005
['Munich', 'Steven Spielberg']  

Answer 1

您没有使用x(我建议一个更好的名称)。

此代码适用于 Python 2.7 和 Python 3.x:

films = {
"2005": ["Munich", "Steven Spielberg"], 
"2006": [["The Prestige", "Christopher Nolan"], ["The Departed", "Martin Scorsese"]]
}

for year in sorted(films.keys()):
    print(year)
    if isinstance(films[year][0], list):
        films_list = films[year]
    else:
        films_list = [films[year]]
    for film in films_list:
        print(", ".join(film))
    print("")
