如何在使用python將CSV文件附加到另一個CSV文件時跳過標題

Question

我正在從API接收CSV響應。我想將收到的CSV回覆添加到我的機器中已有的CSV文件中。我面臨的問題是它也從第二個CSV文件追加標題。我想刪除該標題。我還附加了我的csv在追加後的外觀截圖。

response = requests.get(Link) 
actual_file = glob.glob(path_to_data+'\\Data\\*') 
new_target_file = path_to_data+'\\Data'+'\\'+State+'_'+date+'_'+St_Id+'.csv' 
# Write to .CSV 
if not os.path.exists(new_target_file): 
    for x in response.text.split('\n')[1:]: 
     f = open(actual_file[0], "a") 
     f.write(x) 
    f.close() 
    os.rename(actual_file[0],new_target_file) 
else: 
    logging.warning("File already exist")

你的問題是識別響應，行跳過其中，併線保留。假設實際內容在第二行開始，您已經實施切片以在第一行之後提取響應行。根據你描述的症狀，這不是（總是）的情況。

#fully describe header here, 
header="STATION,STATION_ELEVATION,LATITUDE,LONGITUDE,..." 

def isheader(line,header,delim=','): 
    l = line.split(delim) #may want to fold case 
    h = header.split(delim) #may want to fold case 
    n = sum(list(set(l) & set(h))) 
    return n==len(h) 

response = requests.get(Link) 
actual_file = glob.glob(path_to_data+'\\Data\\*') 
new_target_file = path_to_data+'\\Data'+'\\'+State+'_'+date+'_'+St_Id+'.csv' 
# Write to .CSV 
if not os.path.exists(new_target_file): 
    with open(actual_file[0], "a") as f: 
     for x in response.text.split('\n')[1:]: 
      if len(x) < 2: continue #skip empty lines 
      if isheader(x,header,','): continue #skip header 
      f.write(x+'\n') 
    #with performs close automatically 
    os.rename(actual_file[0],new_target_file) 
else: 
    logging.warning("File already exist")
