打印CSV中的前6行然後開始讀取

所以我有一個CSV，我試圖打印出頭6行，然後啓動代碼。我是超級新手。我知道如何跳過下一個（閱讀器）的前6行，但我需要打印前5行，因爲它是標題，然後在數據開始的第8行啓動腳本。所以我認爲這是讀者=之後的某種打印語句，然後可能是下一個（讀者）之後啓動代碼。只是我的理論。打印CSV中的前6行然後開始讀取

import csv 

with open('GAT_US_PartReview_2017-06-23.csv', newline='') as f: 
    reader = csv.reader(f) 



    for row in reader: 
     hqline, part_no, part_class, appl_req, appl_count, intr_req, 
     intr_count, oe_intr, has_oe_intr, has_attr_editor, 
     part_IMG_req, has_part_img, has_part_img, has_mpcc, warr_req, 
     warr_txt, warr_pdf, msds_req, has_msds, upc_req, has_upc, 
     has_unspsc, attr_count, attrval_count, valid_part = row

而不是圖像..你可以發佈一些示例輸出內容。所以我可以複製它並檢查？ – void

發佈...它有點看起來很醜。讓我知道是否有更好的方法。 –

你爲什麼不嘗試枚舉？

import csv 

with open('GAT_US_PartReview_2017-06-23.csv', newline='') as f: 
    reader = csv.reader(f) 

    for row_num, row in enumerate(reader): 
     if row_num <= 5: 
      print row # Print out the header 
     else: 
      hqline, part_no, part_class, appl_req, appl_count, intr_req, 
      intr_count, oe_intr, has_oe_intr, has_attr_editor, 
      part_IMG_req, has_part_img, has_part_img, has_mpcc, warr_req, 
      warr_txt, warr_pdf, msds_req, has_msds, upc_req, has_upc, 
      has_unspsc, attr_count, attrval_count, valid_part = row

這個工程！只需要一些tweeking從CSV中擺脫所有醜陋的撇號和逗號。 –

現在的問題是讓腳本開始在第8行上運行lol –

我想你可以找出那一個;） –

那麼簡單跳過這些前六行然後使用一個簡單的if..else

例csv文件：

Supplier, GAT 
Summary, Parts 
ACCT no, 40404 
RecCount, 10122 
App Date, june 14,2017 

HQ,Part No, Part class, Stuff, Other stuff 
GAT,'27211',O,NO,0 
GAT,'27212',O,YES,0 
GAT,'99999',O,NOPE,0

代碼：

import csv 

stuff = [] 

with open('test_file.csv', newline='') as f: 
    freader = csv.reader(f) 
    count=0 
    for line in freader: 
     count+=1 
     if count>6: 
      hqline, part_no, part_class, appl_req, appl_count=line 
      print(hqline, part_no, part_class, appl_req, appl_count) 
     else: 
      stuff.append(line) 


print("-----------------------------------") 
print(stuff)

輸出：

HQ Part No Part class Stuff Other stuff 
GAT '27211' O NO 0 
GAT '27212' O YES 0 
GAT '99999' O NOPE 0 
----------------------------------- 
[['Supplier', ' GAT '], ['Summary', ' Parts '], ['ACCT no', ' 40404'], ['RecCount', ' 10122'], ['App Date', ' june 14', '2017'], []] 
>>>

所以基本上如果計數小於或等於六個I我只是追加那些沒人要的字符串stuff列表。

stuff.append(line)

如果線大於6我拆包他們爲你想要的。

hqline, part_no, part_class, appl_req, appl_count=line

希望這對你很清楚。

Ofcourse您可以打印它們。我只是附加給你解釋這個概念。
