Python 似乎无法正确识别输入

问：

我正在做一个基本项目，在 Python 中扫描 CSV 文件以查找已购买产品的特定标识符。以下是相关列的销售电子表格的前几行：

Saturday Pass - 4/20
Saturday Pass - 4/20
Workshop Pass (4/19-4/21)
Friday 4/19 Concert @ 8pm
Friday 4/19 Concert @ 8pm
Sunday Pass - 4/21
Friday 4/19 Concert @ 8pm
Saturday 4/20 Concert @ 8pm
Friday 4/19 Concert @ 8pm
Panel Discussion
Friday Pass - 4/19

Workshop Pass (4/19-4/21)

这是我的代码：

import csv
from collections import Counter
#open file to read
with open('test.csv', mode =
          'r',) as f:
    #define the dataset
    readed = csv.reader(f)
    for row in readed:
        #define the searched string
        numbertofind = "Workshop Pass (4/19-4/21)\n"
        #search for string
        if numbertofind == row[17]:
            print("found")
        else:
            #print details if not found
            print(row[17])           

我对 Python 相当陌生，我尝试过改变我的方法，而是遍历一列，但我找不到有效的方法。

如果有人对此有解决方案，或者有办法使这段代码变得更好，您的意见将不胜感激。

为了进一步确认，（也许是显而易见的）代码的输出只是每行的第 17 个值（产品类型）。我认为没有必要发布，因为我们在上面发布了输出的 1/4 值。
