例如,有一个字典如下:
>>> dic = { "name": "botoo", "url": "http://www.123.com", "page": "88", "isNonProfit": "true", "address": "china", }
想要得到的输出结果如下:

首先获取字典的最大值max(map(len, dic.keys()))
然后使用
Str.rjust() 右对齐
或者
Str.ljust() 左对齐
或者
Str.center() 居中的方法有序列的输出。
>>> dic = { "name": "botoo", "url": "http://www.123.com", "page": "88", "isNonProfit": "true", "address": "china", } >>> >>> d = max(map(len, dic.keys())) #获取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 >>>
关于 str.ljust()的用法还有这样的;
>>> s = "adc" >>> s.ljust(20,"+") 'adc+++++++++++++++++' >>> s.rjust(20) ' adc' >>> s.center(20,"+") '++++++++adc+++++++++' >>>
