來自多行的彙總文本字段（javascript/python）

Question

首先，我想讓你知道我在編碼方面比較新，而且我只有Python和Javascript的膚淺知識。

我有一個包含名稱及其在數據結構隊名這個巨大的TXT如下：

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

理想情況下，我想提取我的數據由Team＃搜索和返回的人屬於名稱到它。

例如，我需要team1和team2的組件。我的新TXT輸出應該是這樣的：

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

非常感謝您的幫助

Answer 1

一個Python版本，可以看看這個：

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()) 

輸出：

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

只要做到這一點讀取和寫入到一個實際的文件：

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

EDIT

注：樣品的數據似乎不包含的情況下woud導致多個名稱在輸出一行。

隨着this input data，我們需要改變的代碼：

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))
