Question

我想要一个包含三个列表数据的单个字符串

喜欢

 list_1 = ['Modified', 'Modified', 'Added', 'Added']
 list_2 = ['92', '92', '92', '92'] 
 list_3 = ['trunk/new','trunk', 'branch','oldpath']

我的字符串应该是：

 "Modified/92 trunk/new 
  Modified/92 trunk
  Added/92 branch
  Added/92 oldpath"

如何添加这些列表得到这种字符串？

Answer 1

您可以在此处使用str.join，zip和一些string formatting：

>>> s =  '\n'.join('{0}/{1} {2}'.format(*x) for x in zip(list_1, list_2, list_3))
>>> print s
Modified/92 trunk/new
Modified/92 trunk
Added/92 branch
Added/92 oldpath

使用itertools.starmap的另一种选择：

>>> from itertools import starmap, izip
>>> f = '{0}/{1} {2}'.format
>>> print '\n'.join(starmap(f, izip(list_1, list_2, list_3)))
Modified/92 trunk/new
Modified/92 trunk
Added/92 branch
Added/92 oldpath

如果您只需要字符串打印目的，那么不要创建字符串，只需使用print()函数：

>>> from __future__ import print_function  #Required in Python 2
>>> print(*starmap(f, izip(list_1, list_2, list_3)), sep='\n')
Modified/92 trunk/new
Modified/92 trunk
Added/92 branch
Added/92 oldpath

Answer 2

你可以这样做：

list_1 = ['Modified', 'Modified', 'Added', 'Added']
list_2 = ['92', '92', '92', '92'] 
list_3 = ['trunk/new','trunk', 'branch','oldpath']

s = ' '.join(a+'/'+b+' '+c for a,b,c in zip(list_1, list_2, list_3))   #for separation with spaces

或者

s = '\n'.join(a+'/'+b+' '+c for a,b,c in zip(list_1, list_2, list_3))  #for new lines

[OUTPUT]
Modified/92 trunk/new Modified/92 trunk Added/92 branch Added/92 oldpath
