我需要从我读过的CSV文件中划分空格

import csv

aList=[]
with open(self.filename, 'r') as f:
    reader = csv.reader(f, delimiter=',', quoting=csv.QUOTE_NONE)
    for row in reader:
        aList.append(row)
    # I need to strip the extra white space from each string in the row
    return(aList)

我有一个gui,当按下一个按钮时会初始化askopenfilename但是我想能够解释用户在askopenfilename对话框上选择取消的时间

这是我处理单击按钮的功能,但if语句行似乎不起作用!

def openFileClicked(self):
  self.filename=filedialog.askopenfilename()
  if self.filename== None: 
        self.e.config(state= NORMAL)
        self.e.delete(0,END)
        self.e.insert(0,"...")
        self.e.config(state="readonly")
  self.e.config(state= NORMAL)
  self.e.delete(0,END)
  self.e.insert(0, self.filename)
  self.e.config(state="readonly")
  print ((self.filename))

我总结了列表中的2个数字并根据该总和进行排序后需要排序的列表.列表如下.任何建议将不胜感激.

myList = [['X5QR76', 3, 7], ['G77652', 1, 5], ['GT1885', 5, 2], ['WB2013', 5, 2], ['FINBOX', 2, 9]]
