当我的代码出现在范围内时，为什么我得到IndexError：列表索引超出范围？

Question

我正在编写一个名为“我的倒计时日历”的项目。我差不多完成了，所以我给了我迄今为止的测试运行。我最终得到这个错误。 这是我的代码。

from tkinter import Tk, Canvas 
from datetime import date, datetime 

def gete(): 
    liste = [] 
    with open('events.txt') as file: 
     for line in file: 
      line = line.rstrip('\n') 
      currente = line.split(',') 

      eventd = datetime.strptime(currente[1], '%d/%m/%y').date() 
      currente[1] = eventd 
      liste.append(currente) 
     return liste 
def daysbd(date1, date2): 
    timeb = str(date1-date2) 
    numberofd = timeb.split(' ') 
    return numberofd[0] 

root = Tk() 

c = Canvas(root, width=800, height=800, bg='black') 
c.pack() 
c.create_text(100, 50, anchor='w', fill='orange', font = 'Arial 28 bold underline', text = 'My Countdown Calendar') 


events = gete() 
today = date.today() 

for event in events: 
    eventn = event[0] 
    daysu = daysbd(event[1], today) 
    display = 'It is %s days until %s ' % (daysu, eventn) 
    c.create_text(100, 100, anchor='w', fill='lightblue',\ 
        font = 'Arial 28 bold ', text = display)

解析文本文件时，几乎总是希望跳过空行。下面是这个的idomatic模式：

for line in file: 
    line = line.strip() 
    if not line: 
     continue 
    # process line 

如果你的文件格式取决于空白的非空行，你可以加入线2和3 if not line.strip()。
