python3.x - python 字符串操作，空格对齐

Question

我是用这个函数使他距离左边20，分别对每一句给一个不同的间距值

str1.rjust(20, ' ')
str2..rjust(19, ' ')
如图：

改怎么写才能使得百分比区域的值在同一行，或者说间距最左边的值固定。谢谢

Answer 1

Use format string

>>> '%-20s%s'%('aaa','99.9%')
'aaa                 99.9%'
>>> '%-20s%s'%('ccccccccc','70.1%')
'ccccccccc           70.1%'

Floating point numbers~
'%-20s%5.2f%%'

>>> '%-20s%5.2f%%'%('ddddd',1)
'ddddd                1.00%'
>>> '%-20s%5.2f%%'%('dddddaaaaa',99.9)
'dddddaaaaa          99.90%'
