閱讀CSV，新的CSV寫信息，並通過柱

Question

排序的東西，從csv取值和在一個句子並將其寫入到一個新的CSV工作：

import csv 

with open('Links.csv', 'rb') as input_file, \ 
open('Link Statements.csv', 'w') as output_file: 

reader = csv.reader(input_file, delimiter=',', quoting=csv.QUOTE_NONE) 

for row in reader: 
    link_name, from_unit, to_unit, rate, type = row 
    output_file.write(" %s," % (from_unit)) 
    output_file.write("Establish %s link %s at %s Kbps to %s.\n" % (type, link_name, rate, to_unit)) 
    output_file.write(" %s," % (to_unit)) 
    output_file.write("Terminate %s link %s at %s Kbps from %s.\n" % (type, link_name, rate, from_unit)) 

這需要以下內容：

MPP01,RCT-6,1/6,14336,LOS UHF MCR 
SIPRPP01,RCT-6,1/6,8192,SIPRNET 
NIPRPP02,RCT-6,2/6,4096,NIPRNET 
BSPEPP03,RCT-6,1/10,472,BSPE 
DPV0PP04,1/10,2/6,472,DPV0 
SIPRPP04,1/6,1/3,8192,SIPRNET 
NIPRPP03,1/6,1/10,8192,NIPRNET 
SIPRPP03,3/6,1/10,4096,NIPRNET 
NIPRZP01,MEB,RCT-6,8192,NIPRNET 
SIPRZP01,MEB,RCT-6,4096,SIPRNET 

，並寫入到這個新文件：

RCT-6,Establish LOS UHF MCR link MPP01 at 14336 Kbps to 1/6. 
1/6,Terminate LOS UHF MCR link MPP01 at 14336 Kbps from RCT-6. 
RCT-6,Establish SIPRNET link SIPRPP01 at 8192 Kbps to 1/6. 
1/6,Terminate SIPRNET link SIPRPP01 at 8192 Kbps from RCT-6. 
RCT-6,Establish NIPRNET link NIPRPP02 at 4096 Kbps to 2/6. 
2/6,Terminate NIPRNET link NIPRPP02 at 4096 Kbps from RCT-6. 
RCT-6,Establish BSPE link BSPEPP03 at 472 Kbps to 1/10. 
1/10,Terminate BSPE link BSPEPP03 at 472 Kbps from RCT-6. 
1/10,Establish DPV0 link DPV0PP04 at 472 Kbps to 2/6. 
2/6,Terminate DPV0 link DPV0PP04 at 472 Kbps from 1/10. 
1/6,Establish SIPRNET link SIPRPP04 at 8192 Kbps to 1/3. 
1/3,Terminate SIPRNET link SIPRPP04 at 8192 Kbps from 1/6. 
1/6,Establish NIPRNET link NIPRPP03 at 8192 Kbps to 1/10. 
1/10,Terminate NIPRNET link NIPRPP03 at 8192 Kbps from 1/6. 
3/6,Establish NIPRNET link SIPRPP03 at 4096 Kbps to 1/10. 
1/10,Terminate NIPRNET link SIPRPP03 at 4096 Kbps from 3/6. 
MEB,Establish NIPRNET link NIPRZP01 at 8192 Kbps to RCT-6. 
RCT-6,Terminate NIPRNET link NIPRZP01 at 8192 Kbps from MEB. 
MEB,Establish SIPRNET link SIPRZP01 at 4096 Kbps to RCT-6. 
RCT-6,Terminate SIPRNET link SIPRZP01 at 4096 Kbps from MEB. 

我想組一起陳述基於whic h任務是針對哪些單元的 - 我通過在第一列中寫入相關單元來完成此任務，然後我可以通過在Excel中手動排序將相關任務分組到每個單元。

有沒有辦法讓程序在將數據寫入新的csv時對數據進行排序？或者有沒有辦法，我可以這樣組合他們：

1/6 
Terminate... 
Establish... 

2/6 
Terminate... 
Establish... 
Establish... 

3/6 
Terminate... 
Terminate... 

我欣賞任何幫助，我可以得到與此。

你應該列存儲在列表中的詞典，然後寫字典出的結果文件：

import csv 
from collections import defaultdict 

d = defaultdict(list) 

with open('Links.csv', 'rb') as inf: 
    reader = csv.reader(inf, delimiter=',', quoting=csv.QUOTE_NONE) 
    for row in reader: 
     d[row[2]].append(row) 

with open('outfile.csv', 'w') as outf: 
    for k,v in d.iteritems(): 
     outf.write('{}\n'.format(k)) 
     for i in v: 
      up = '{1},Establish {4} link {0} at {3} Kbps to {2}.\n' 
      down = up.replace('Establish','Terminate').replace('to','from') 
      outf.write(up.format(*i)) 
      outf.write(down.format(*i)) 
     outf.write('\n')
