Question

我正在尝试打印csv文件中的每一行，但是它将仅打印第一行。这是负责的代码：

var request = (HttpWebRequest) WebRequest.Create("https://analytics.itunes.apple.com/#/apps?t=apps&interval=r&datesel=d30");
request.Headers["Host"] = "analytics.itunes.apple.com";
request.Headers["Connection"] = "keep-alive";
request.Headers["User-Agent"] = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36";
    request.Headers["Accept"] = "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8";
    request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
    request.Headers["Accept-Language"] = "uk-UA,uk;q=0.9,ru;q=0.8,en-US;q=0.7,en;q=0.6";
    request.Headers["Cache-Control"] = "max-age=0";
    request.Headers["Upgrade-Insecure-Requests"] = "1";

如果需要，这里是完整的代码：

    if option == '1':
    with open("songs.csv") as f:
        reader = csv.reader(f)
        for row in reader:
            output = (row[0], row[1], row[2]) #Only outputs 1 song ?
            print (output)

预先感谢您：）

列出歌曲的代码部分对我有用。

if option == '1':
    with open("songs.csv") as f:
        reader = csv.reader(f)
        for row in reader:
            output = (row[0], row[1], row[2]) #Only outputs 1 song ?
            print (output)

但是，您在循环时编写的内容，例如

outputtxt_check = False

                while outputtxt_check == False:
                    outputtxt = input(
                        "Would you like to output this list to a text file? Enter 1 for yes or 2 for no: ")

在同一for循环中发生

。这就是为什么它只打印一行。您正在问用户问题，因为for循环尚未完成所有歌曲的打印。尝试将while循环放在for循环的外部/之后。

只打印一行csv文件
