在csv文件中搜索术语不起作用

Question

一个按钮激活了下面的功能，但似乎不起作用，有人知道为什么吗？你知道吗

        with open (r"D:\Users\gblmac\Desktop\Visitor GUI\Site Visitors.csv") as csvread:
        search_term=self.textEdit_Search.toPlainText()
        print(search_term)
        search=csv.reader(csvread)
        for row in search:
            if search_term in row:
                print(row)

csv文件如下所示：

2000年1月1日，a，a，a，是的，是的，是的，a

2000年1月1日，b，b，b，是的，是的，是的，b

2000年1月1日，莱斯利·麦金托什，范德兰，工作，莱斯·麦克，是的，是的，不是，不适用，没有！你知道吗

2000年1月1日，斯蒂芬·马什，范德兰德，工作，莱斯·麦克，是的，是的，不是，不适用，没有！你知道吗

2000年1月1日，伊恩·哈顿，范德兰德，工作，莱斯·麦克，是，是，不，不适用，没有！你知道吗

2000年1月1日，西蒙·米尔斯，范德兰德，工作，西蒙·米尔斯，是，是，不是，不适用，没有！你知道吗

因此，如前所述，如果搜索词是“莱斯利”，我希望第三行打印出来，但它没有。你知道吗

搜索词按如下方式打印：

    search_term=self.textEdit_Search.toPlainText()
    print(search_term)

但我随后收到一条“Python已经停止工作”的错误消息，并且没有打印任何内容。你知道吗

Answer 1

使用AlexanderReynolds suggestion in the comments标识行中的术语，然后可以打印整行：

def search_visitor(self):
    with open (r"Site Visitors.csv") as csvread:
        search_term=self.textEdit_Search.toPlainText().lower()
        search=csv.reader(csvread)
        for n, row in enumerate(search, 1):
            for col in row:
                if search_term in col.lower():
                    print('Line {}: {}'.format(n, ' '.join(row)))

确认在第3行找到搜索项：
