python中如何右对齐
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+++++++++'
