如果我使用空間分隔符分割的文件,列將是(逗號被包括在一些列):

我試圖做的(例如第一列):
list = []
with open('D:\GIS\Sentinel\cmd_output.txt', 'r') as file:
reader = csv.reader (file, delimiter = ' ')
for a,b,c,d,e,f,g,h,i,j,k,l,m,n in reader:
list.append(a)
print list
但它不工作,併發送錯誤:
ValueError: need more than 1 value to unpack
如何爲文件中的每個列執行此操作? 謝謝!

我不知道該怎麼做。我不是Python的高級用戶。 – Litwos
你能展示實際的追溯?你爲什麼只是追加一個?它看起來像'產品'的價值? –
