我正在尝试在运行 OS X Yosemite (10.10.5) 的 Mac 上使用以下 Python 脚本连接到我的 ftp 服务器：

from ftplib import FTP
import ConfigParser

config_file = "ftp.config"
config = ConfigParser.ConfigParser()
try:
    config.read(config_file)
except:
    raise Exception("Failed reading {} file.").format(config_file)

server_address  = config.get("main", "server")
user_name = config.get("main", "user_name")
password  = config.get("main", "password")

ftp = FTP(server_address)
ftp.login(user_name, password)
print "Logging in as '{}'".format(user_name)

该脚本从文件“ftp.config”中获取服务器信息，内容如下：

[main]
enable      =   1
server      =   "my.ftp.address"
user_name   =   "some_user_name"
password    =   "some_password"

当我运行脚本时，出现以下错误：

Traceback (most recent call last):  
    File "ftp2.py", line 34, in <module> …

首先,这似乎是一个学习更多编程的好地方.我编写了一个maya python脚本,其中两个函数都有效,但我无法通过UI按钮来调用superExtrude()函数.第一个函数执行几何网格操作,第二个函数应该为用户输入生成UI:

import maya.cmds as cmds

def superExtrude(extrScale, extrDist):
    """Loops through a list of selected meshes and extrudes all of the mesh faces to produce a polygon frame, based on existing mesh tesselations"""
    myObjectLt = cmds.ls(selection=True)

    for i in range(len(myObjectLt)):
        numFaces = cmds.polyEvaluate(face=True)
        item = myObjectLt[i] + ".f[:]"
        cmds.select(clear=True)
        cmds.select(item, replace=True)

        #extrude by scale
        cmds.polyExtrudeFacet(constructionHistory=True, keepFacesTogether=False, localScaleX=extrScale, localScaleY=extrScale, localScaleZ=extrScale)
        selFaces = cmds.ls(selection=True)
        cmds.delete(selFaces)

        #extrude by height
        cmds.select(item, replace=True)
        cmds.polyExtrudeFacet(constructionHistory=True, keepFacesTogether=True, localTranslateZ=extrDist)

def extrWindow():
    """Creates the user interface UI for the …
