现在，对于

new\u to\u csv

中的每个

x[0]

，我首先检查它是否是一个数字。如果是数字Iam，则会在

mini

和

maxi

之间进行检查。我抓取它所在行的列

3:8

，并将其粘贴到列表后面。如果

x[0]

不是一个数字，我将跳过它并将“unknown”写入输出

这是我的代码：

table_x = r"C:\Users\ELK\Downloads\table_x.txt"

result_list = []
with open(table_x, "r") as outer:
    reader = csv.reader(outer, delimiter="\t")
    next(reader) #skip the first 4 lines
    next(reader)
    next(reader)
    next(reader)
    for row in reader:
        mini = row[1]  
        maxi = row[2]  
        for x in new_to_csv:
            veh_number = x[0]
            check_digit = veh_number.isdigit()
            if check_digit:   #<--- check if its digit
                if int(veh_number) > int(mini) and int(veh_number) < int(maxi):
                    result_list.append(x+ [row[3]]+ [row[4]]+ [row[5]]+ [row[6]]+ [row[7]]+ [row[8]])
            if check_digit is False: #if its not digit
                result_list.append(x + [row[3]] + [row[4]] + [row[5]] + ["Unkown"])

print(result_list)

上面是我期望的输出

是一个数字，介于

和

之间，因此我从该行中获取列

3:8

<代码>*021不是一个数字，所以我写

“未知”

等等

下面你可以看到我收到的输出，它似乎对非数字进行了多次处理。我不明白为什么

这是我收到的输出：

把你的台词换成它

if check_digit is False: #if its not digit
      result_list.append(x + ["Unkown"] + ["Unkown"] + [""] + ["Unkown"])

您正在将[row[3]]+[row[4]]+[row[5]]添加到x

*****完整代码*****

table_x = r"table_x.txt"

result_list = []
with open(table_x, "r") as outer:
    reader = csv.reader(outer, delimiter="\t")
    next(reader) #skip the first 4 lines
    next(reader)
    next(reader)
    next(reader)
    for row in reader:
        mini = row[1]  
        maxi = row[2]


        for x in new_to_csv:
            veh_number = x[0]
            check_digit = veh_number.isdigit()
            if check_digit:   #<--- check if its digit
                if int(veh_number) > int(mini) and int(veh_number) < int(maxi):
                    result_list.append(x+ [row[3]]+ [row[4]]+ [row[5]]+ [row[6]]+ [row[7]]+ [row[8]])

    for x in new_to_csv:
        veh_number = x[0]
        check_digit = veh_number.isdigit()
        if check_digit is False: #if its not digit
            result_list.append(x + ["Unkown"] + ["Unkown"] + [""] + ["Unkown"])
print(result_list)

table_x=r“table_x.txt”
结果_列表=[]
以开放式（表x，“r”）为外部：
reader=csv.reader（外部，分隔符=“\t”）
下一步（读者）#跳过前4行
下一位（读者）
下一位（读者）
下一位（读者）
对于读取器中的行：
mini=行[1]
maxi=行[2]
对于新的\u到\u csv中的x：
车辆编号=x[0]
检查数字=车辆编号.isdigit（）
如果检查数字：#int（mini）和int（veh_number）

为什么预期输出中有

'Unknown'，'Unknown'，'Unknown'，'Unknown'

，而没有一个'Unknown'，也没有与第3:8列的字段数相同的'Unknown'？@00我真的不知道。。您的意思是什么？您应该分别读取表_x（在循环中），将结果存储在变量中（可能是dict或类似的），然后分别迭代新的_到_csv。现在，您正在迭代表x中的新的到csv。这将不能按原样工作。@00但为什么数字工作正常？这个问题似乎只出现在非数字上。我的意思是，您声明“如果x[0]不是数字，我将跳过它并将“未知”写入输出。”。然而，第一列不是数字的预期输出有3次“未知”加上一个空字符串；根据那句话，没有一个“未知”。这样做了，但我的列表中仍然有很多非数字。你能分享结果列表吗？我不能在这里分享，因为它太大了。问题是你把它附加在两个循环中，一个用于列表，一个用于txt文件。每次在列表循环中，都会追加result_list.append（x++[“未知”]+[“未知”]+[“未知”]+[“未知”]）。所以，若你们的txt文件有10行，在你们的列表中有10行，这意味着，你们的最终列表将以10*10行=100行结束。谢谢你们。真的很有帮助。
