python字符串对齐格式

Question

我在python中有一些字符串，我想互相帮助，但似乎无法做到。

 a = ("adam, home, wednesday, 17th")
 b = ("Tiffany, office, monday, 9th")

我把它们分开了“，”

我想输出：

 adam         home     wednesday     17th
 tiffany      office   monday        9th

我正在尝试使用

 working_line =('{0} {1:<20} {2:<15} {3:<10}'.format(source,group,symbol,position))

这不起作用，我有点困惑......

Answer 1

{3}字段定义中缺少冒号：

working_line =('{0} {1:<20} {2:<15} {3:<10}'.format(source,group,symbol,position))

Answer 2

你怎么做这样的事情：

a = ['adam', 'home', 'wednesday', '17th']
b = ['Tiffany', 'office', 'monday', '9th']

for x in [a, b]:
    working_line = ' '.join(map(lambda s: s.ljust(10, ' '), x))
    print working_line

这是输出：

adam       home       wednesday  17th      
Tiffany    office     monday     9th
