我是Python的新手，我有一个加密交换列表，我想与add_action('save_post', 'save_my_music_links');
function save_my_music_links($post_id)
{
if (!isset($_POST['link-music[]'])) {
return;
}
if(defined('DOING_AUTOSAVE' && DOING_AUTOSAVE)){
return;
}
$my_links = sanitize_text_field($_POST['link-music[]']);
update_post_meta($post_id, 'music-links', $my_links);
}
库连接以获取OHLC数据。
但是为了逐个实例化每个交换类（许多对象），我想创建一个包含列表中所有交换数据的 Dim UserName As String
' Sets Username to current logged-in user profile
UserName = Environment.UserName
Dim JobNo As String
JobNo = Textbox1.Text
'DOWNLOADING FROM THE FTP JOBS PROCESSED FOLDER
Dim listRequest As FtpWebRequest = WebRequest.Create(“ftp.site.com/input/” & JobNo & "_*.DBF")
listRequest.Credentials = New System.Net.NetworkCredential(“Username”, “Password”)
listRequest.Method = WebRequestMethods.Ftp.ListDirectory
Dim listResponse As FtpWebResponse = listRequest.GetResponse()
Dim reader As StreamReader = New System.IO.StreamReader(listResponse.GetResponseStream())
Dim Filedata As String = reader.ReadToEnd
Dim directory() As String = Filedata.Split(New String() {Environment.NewLine}, StringSplitOptions.RemoveEmptyEntries)
'CREATES TEAM FILE FOLDERS ON LOCAL COMPUTER
My.Computer.FileSystem.CreateDirectory("C:\users\" & UserName & "\desktop\TEAMFILES\IMB_APPEND\A_TEAM")
My.Computer.FileSystem.CreateDirectory("C:\users\" & UserName & "\desktop\TEAMFILES\IMB_APPEND\B_TEAM")
'CLEAR TEXTBOX2
TextBox2.Clear()
For Each foundFile As String In directory
ATEAMdown(foundFile)
TextBox2.Text = TextBox2.Text & foundFile & vbNewLine
Next

对象，以便我可以请求第一个交换的数据ccxt，来自第二位的数据exchanges等
exchanges[0]使用r我会使用exchanges[1]，但我怎样才能在Python中实现这一点？
答案 0 :(得分：6)
只需使用getattr(...)和列表comp。
exchanges = [getattr(ccxt, e)() for e in ex]
然后您可以按索引访问所有三个交易所。

有什么问题
junk <- Map(`assign`, v1, v2, MoreArgs = list(envir = environment()))
