導出爲CSV將所有字符分隔爲字段

我在編寫一個python腳本時遇到了一些問題，以審覈我公司的許多不同應用程序中的所有CSV文件，而且我幾乎用概念帶給老闆，並炫耀我可以用python做什麼，但問題是，我不明白在python中的CSV類所有這一切以及......導出爲CSV將所有字符分隔爲字段

這是一個例子，計算機信息列表如下所示：

['EB-ABORTZ,True,False,False,0', 'EB-AGONCHAROVA,True,False,False,0', 
'EB-AHART-1,True,False,False,0', 'EB-AHEIDENREICH,True,False,False,0', 
'EB-ALOCKLEAR,True,False,False,0', 'EB-AMARGULIS,True,False,False,0', 
'EB-ASKLAR,True,False,False,0', 'EB-ASKLAR-1,True,False,False,0', 
'EB-ASKLAR-3,True,False,False,0', 'EB-BCHOW-1,True,False,False,0', 
'EB-BJOHNSON,True,False,False,0', 'EB-BLYLE,True,False,False,0', 
'EB-BRUSSUM,True,False,False,0', 'EB-CCLEARY,True,False,False,0', 
'EB-...]

，這裏是什麼在最後的代碼會產生一個例子.....

"E","B","-","A","B","O","R","T","Z",",","T","r","u","e",",","F","a","l","s","e",",","F","a","l","s","e",",","0" 
"E","B","-","A","G","O","N","C","H","A","R","O","V","A",",","T","r","u","e",",","F","a","l","s","e",",","F","a","l","s","e",",","0" 
"E","B","-","A","H","A","R","T","-","1",",","T","r","u","e",",","F","a","l","s","e",",","F","a","l","s","e",",","0" 
"E","B","-","A","H","E","I","D","E","N","R","E","I","C","H",",","T","r","u","e",",","F","a","l","s","e",",","F","a","l","s","e",",","0" 
"E","B","-","A","L","O","C","K","L","E","A","R",",","T","r","u","e",",","F","a","l","s","e",",","F","a","l","s","e",",","0" 
"E","B","-","A","M","A","R","G","U","L","I","S",",","T","r","u","e",",","F","a","l","s","e",",","F","a","l","s","e",",","0"

下面是我用來嘗試在事後將數據導出爲CSV格式的方法的副本。

def collate_computers(computers): 
    with open('results.csv', 'w', encoding='utf8',)as outfile: 
     writer = csv.writer(outfile, quoting=csv.QUOTE_ALL, delimiter=',') 
     for c in computers: 
      writer.writerow(c)

究竟是什麼問題了嗎？我可以正確使用你的代碼。什麼是您的預期輸出？ – MaThMaX

的CSV作家功能，writerow，將列表作爲輸入並將每個元素寫入該行。當您將單個字符串傳遞給函數時，作者將該字符串解釋爲字符列表。

我假設你想寫出每一行的字符串出現。因此，而不是使用writer.writerow(c)，使用writer.writerow(c.split(','))。這將字符串分割成一個用逗號分隔的列表。然後

CSV文件應該是這樣的：

EB-ABORTZ,True,False,False,0 
EB-AGONCHAROVA,True,False,False,0 
EB-AHART-1,True,False,False,0 
EB-AHEIDENREICH,True,False,False,0 
EB-ALOCKLEAR,True,False,False,0 
EB-AMARGULIS,True,False,False,0 
EB-ASKLAR,True,False,False,0 
EB-ASKLAR-1,True,False,False,0 
EB-ASKLAR-3,True,False,False,0 
EB-BCHOW-1,True,False,False,0 
EB-BJOHNSON,True,False,False,0 
EB-BLYLE,True,False,False,0 
EB-BRUSSUM,True,False,False,0 
EB-CCLEARY,True,False,False,0

這工作！我希望這不是我錯過的東西！ –

原樣，則產生的寫入行方法逗號分隔值（.csv）

csv模塊不直接支持讀取和寫入的Unicode，但它是8比特請使用ASCII NUL 字符清除一些問題。因此，只要避免使用NUL的編碼，如 UTF-16，就可以編寫處理編碼和解碼的函數或類。建議使用UTF-8。更多信息here

如果您想每行1串（即每行1個列表項）

with open('results.csv', 'w') as outfile: 
    csvWriter = csv.writer(outfile) 
    for c in computers: 
     csvWriter.writerow([c.encode('utf-8')])

的問題是在computers每一項都是一個字符串，在Python字符串字符序列，所以writer.writerow()認爲每個字符是一個單獨的字段。爲了解決這個問題，你需要先split每個字符串分解成田，其中逗號都在上面：

import csv 

def collate_computers(computers): 
    with open('results.csv', 'w', encoding='utf8') as outfile: 
     writer = csv.writer(outfile, quoting=csv.QUOTE_ALL, delimiter=',') 
     for s in computers: 
      fields = s.split(',') 
      writer.writerow(fields) 

computers = [ 
    "EB-ABORTZ,True,False,False,0", 
    "EB-AGONCHAROVA,True,False,False,0", 
    "EB-AHART-1,True,False,False,0", 
    "EB-AHEIDENREICH,True,False,False,0", 
    "EB-ALOCKLEAR,True,False,False,0", 
    "EB-AMARGULIS,True,False,False,0" 
] 

collate_computers(computers)

results.csv

"EB-ABORTZ","True","False","False","0" 
"EB-AGONCHAROVA","True","False","False","0" 
"EB-AHART-1","True","False","False","0" 
"EB-AHEIDENREICH","True","False","False","0" 
"EB-ALOCKLEAR","True","False","False","0" 
"EB-AMARGULIS","True","False","False","0"
