導出不完整

這是我的腳本：導出不完整

l_final = [(k, list(v)) for k,v in groupby(l_clean, key = operator.itemgetter(1))] 

for k,v in l_final: 
    info_rest = v[0][:5]+v[0][5:] 
    info_combine = map(operator.itemgetter(5),v) 
    uniekid = k

    emailadr = info_rest[8] 
    klantgegevens = [uniekid,naam,verz,risicoadr,polisnummer,relatienummer,aanhef,contactpersoon,emailadr,] 

import csv 
    with open('export.csv', 'w') as f: 
     writer = csv.writer(f) 
     writer.writerows(klantgegevens)

當我寫我得到這個在我的.csv文件的結果：

S l e v e r  k l o p t  4 2

正如你可以看到，他只寫一個它的街道名稱。

任何人都可以幫助我？

你有什麼期望這做？您只需向您的CSV文件寫入一行。如果你想讓它寫多行，你應該將'writer.writerows（...）'移到你的循環中。 – Matt

您只有一個列表（您在每個循環中重置klantgegevens），並且您將該列表編寫爲好像它是一整行多行。

csv模塊看到一個列表作爲一組序列，這意味着每個字符串項被視爲單個字符的序列，而這正是將被寫入到CSV文件：

>>> klantgegevens 
['Slever klopt 42', 'Slever ', ['AVB'], 'klopt 42', 'KD2220115', '17', 'Geachte heer Slever', 'De heer T. Slever', '[email protected]'] 
>>> list(klantgegevens[0]) 
['S', 'l', 'e', 'v', 'e', 'r', ' ', 'k', 'l', 'o', 'p', 't', ' ', '4', '2']

你可以分開來寫的每一行，同時收集klantgegevens列表：

import csv 
with open('export.csv', 'w') as f: 
    writer = csv.writer(f) 
    for k,v in l_final: 
     info_rest = v[0][:5]+v[0][5:] 
     info_combine = map(operator.itemgetter(5),v) 
     uniekid = k 
     verz = info_combine 
     naam = info_rest[0] 
     risicoadr = info_rest[2] 
     polisnummer = info_rest[3] 
     relatienummer = info_rest[4] 
     aanhef = info_rest[6] 
     contactpersoon = info_rest[7] 
     emailadr = info_rest[8] 
     klantgegevens = [uniekid,naam,verz,risicoadr,polisnummer,relatienummer,aanhef,contactpersoon,emailadr,] 
     writer.writerow(klantgegevens)

現在，當你完成它的名單將被視爲列的順序，寫每一行。

或者，你必須收集每個klantgegevens列表到結果列表：

results = []  
for k,v in l_final: 
    # processing 
    klantgegevens = [uniekid,naam,verz,risicoadr,polisnummer,relatienummer,aanhef,contactpersoon,emailadr,] 
    results.append(klantgegevens)

然後列出的該名單寫信給你的CSV文件：

import csv 
with open('export.csv', 'w') as f: 
    writer = csv.writer(f) 
    writer.writerows(results)
