Question

我试图在python中整齐地打印一本字典，但不确定如何这样做。

如果我有字典

mydict = {'Jackson' :['One', 'Two', 'Three'], 'Jeffery' :['Four', 'Five', 'Six']}

我将如何将其打印出来：

Jackson One Two Three

Jeffery Four Five Six

我猜我必须使用for循环，只是想弄清楚如何打印出列表组件。

Answer 1

解决此问题的另一种方法，

def printDictionary(mydict):
    for i in mydict.keys():
        print(i + " " + (" ".join(mydict[i])))

mydict = mydict = {'Jackson' :['One', 'Two', 'Three'], 'Jeffery' :['Four', 'Five', 'Six']}
printDictionary(mydict)

Answer 2

在Python3.6中，您可以使用f字符串

>>> mydict = {
...     'Jackson' :['One', 'Two', 'Three'], 
...     'Jeffery' :['Four','Five', 'Six']
... }

>>> for k,v in mydict.items():
...     print(f"{k} {' '.join(v)}")
... 
Jackson One Two Three
Jeffery Four Five Six

在旧版本的3.x中，您可以使用按键格式

>>> for k,v in mydict.items():
...     print("{k} {vstr}".format(k=k, vstr=" ".join(v)))
... 
Jackson One Two Three
Jeffery Four Five Six

或位置

>>> for k,v in mydict.items():
...     print("{} {}".format(k, " ".join(v)))
... 
Jackson One Two Three
Jeffery Four Five Six

如果你想要简洁，你也可以只使用元组解包（但如果你需要改变输出格式，那就非常灵活了）

>>> for k, v in mydict.items():
...     print(k, *v)
... 
Jackson One Two Three
Jeffery Four Five Six

Answer 3

for key in mydict:
    print(key,end=' ')
    for i in mydict[key]:
        print(i,end='')
    print("\n")

打印出包含密钥和列表的字典
