来自多行的汇总文本字段（javascript/python）

Question

首先，我想让你知道我在编码方面比较新，而且我只有Python和Javascript的肤浅知识。

我有一个包含名称及其在数据结构队名这个巨大的TXT如下：

Name1, Surname1 Team1 
        Team2 
        Team3 
Name2, Surname2 Team2 
        Team4 
Name3, Surname3 Team1 
        Team5 

理想情况下，我想提取我的数据由Team＃搜索和返回的人属于名称到它。

例如，我需要team1和team2的组件。我的新TXT输出应该是这样的：

Team1, Name1, Surname1, Name3, Surname3 
Team2, Name1, Surname1, Name2, Surname2 

非常感谢您的帮助

Answer 1

一个Python版本，可以看看这个：

fobj_in = io.StringIO("""Name1, Surname1 Team1 
        Team2 
        Team3 
Name2, Surname2 Team2 
        Team4 
Name3, Surname3 Team1 
        Team5""") 

fobj_out = io.StringIO() 

from collections import defaultdict 

teams = defaultdict(list) 

for line in fobj_in: 
    items = line.split() 
    if len(items) == 3: 
     name = items[:2] 
     team = items[2] 
    else: 
     team = items[0] 
    teams[team].append(name) 

for team_name in sorted(teams.keys()): 
    fobj_out.write(team_name + ', ') 
    for name in teams[team_name][:-1]: 
     fobj_out.write('{} {}, '.format(name[0], name[1])) 
    name = teams[team_name][-1] 
    fobj_out.write('{} {}\n'.format(name[0], name[1])) 


fobj_out.seek(0) 
print(fobj_out.read()) 

输出：

Team1, Name1, Surname1, Name3, Surname3 
Team2, Name1, Surname1, Name2, Surname2 
Team3, Name1, Surname1 
Team4, Name2, Surname2 
Team5, Name3, Surname3 

只要做到这一点读取和写入到一个实际的文件：

fobj_in = open('in_file.txt') 
fobj_out = open('out_file.txt', 'w') 

EDIT

注：样品的数据似乎不包含的情况下woud导致多个名称在输出一行。

随着this input data，我们需要改变的代码：

from collections import defaultdict 
teams = defaultdict(list) 
for line in fobj_in: 
    if not line.strip(): 
     continue 
    items = [entry.strip() for entry in line.split('\t') if entry] 
    if len(items) == 2: 
     name = items[0] 
     team = items[1] 
    else: 
     team = items[0] 
    teams[team].append(name) 
for team_name in sorted(teams.keys()): 
    fobj_out.write(team_name + ', ') 
    for name in teams[team_name][:-1]: 
     fobj_out.write('{}, '.format(name)) 
    name = teams[team_name][-1] 
    fobj_out.write('{}\n'.format(name))
