Question

def fetch(ent, t):

    # ... your code ...

    # run again after 1000ms
    root.after(1000, fetch, ent, t)

只是打印

追踪（最近一次呼叫最后一次）：

文件“C：\ Users \ Kunal Desai \ workspace \ Kunal \ data.py”，第2行，

打开（r'C：/ Users / Kunal Desai / workspace / Kunal / Kunal.csv'）作为csvfile：

FileNotFoundError：[Errno 2]没有这样的文件或目录：'C：/ Users / Kunal

德赛/工作区/注：Kunal / Kunal.csv'

Python documentation有一个简短的示例，说明如何阅读CSV：

function getClientsInRoom(socketId, room) {
    // get array of socket ids in this room
    var socketIds = io.sockets.adapter.rooms[room];
    console.log("socketIds:" + JSON.stringify(socketIds));
    var clients = [];

    if (socketIds && socketIds.length > 0) {
        //socketsCount = socketIds.lenght;

        // push every client to the result array
        for (var i = 0, len = socketIds.length; i < len; i++) {

            // check if the socket is not the requesting
            // socket
            if (socketIds[i] != socketId) {
                clients.push(chatClients[socketIds[i]]);
            }
        }
    }

    return clients;
}

它显示，>>> import csv >>> with open('eggs.csv', 'rb') as csvfile: ... spamreader = csv.reader(csvfile, delimiter=' ', quotechar='|') ... for row in spamreader: ... print ', '.join(row) Spam, Spam, Spam, Spam, Spam, Baked Beans Spam, Lovely Spam, Wonderful Spam的结果是您必须迭代而不是直接打印它的对象。

任何人都可以帮我这个python程序吗？
