例如，有一個字典如下：

>>> dic = {
"name": "botoo",
"url": "http://www.123.com",
"page": "88",
"isNonProfit": "true",
"address": "china",
}

想要得到的輸出結果如下：

首先 獲取字典 的 最大值 max(map(len, dic.keys()))

然後使用

Str.rjust() 右對齊

或者

Str.ljust() 左對齊

或者

Str.center() 居中的方法有序列的輸出。

>>> dic = {
    
 
"name": "botoo",
    "url": "http://www.123.com",
    "page": "88",
    "isNonProfit": "true",
    "address": "china",
    }
>>> 
>>> d = max(map(len, dic.keys()))  #獲取key的最大值
>>> 
>>> for k in dic:
    print(k.ljust(d),":",dic[k])

    
name        : botoo
url         : http:
 
//www.123.com
page        : 88
isNonProfit : true
address     : china
>>> for k in dic:
    print(k.rjust(d),":",dic[k])

    
       name : botoo
        url : http://www.123.com
       page : 88
isNonProfit : true
    address : china
>>> for k in dic:
    print(k.center(d),":",dic[k])

    
    name    : botoo
    url     : http:
 
//www.123.com
    page    : 88
isNonProfit : true
  address   : china
>>> 

關於 str.ljust()的用法還有這樣的；

>>> s = "adc"
>>> s.ljust(20,"+")
‘adc+++++++++++++++++‘
>>> s.rjust(20)
‘                 adc‘
>>> s.center(20,"+")
‘++++++++adc+++++++++‘
>>>
