所以当我输入 csv 文件中没有的内容时，它就会停止运行

Question

我正在通过搜索打印 CSV 文件中的内容，但如果我输入 CSV 文件中没有的其他名称，它会出于某种原因停止运行。例如，当我输入不在 CSV 文件中的 (hello) 时，它会像结束程序一样停止。我需要帮助来修复我尝试过的 else 语句，但它没有用。我在下面提供了 CSV 文件的图片。

def booking_court()

    location = (console.input("[bold bright_yellow]Please Enter the Name of the Chosen Gym:[/] ").lower().title())
    with open("location2.csv") as csvfile:
        csvreader = csv.reader(csvfile, delimiter=',')
        for idx, row in enumerate(csvreader):
            if idx == 0:
                titles = row
            elif location in row[0]:
                for key, value in zip(titles, row):
                    console.print("[bold yellow]%s: [/][bold blue]%s[/]" % (key, value))
            
                
                console.print("**********************************************************************")

找到匹配项时设置一个变量。在循环结束时检查变量，这样你就可以说没有找到匹配项。

def booking_court()
    console = Console()
    console.print(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>", style="bold blue")
