[英]Why am I getting an IndexError: list index out of range when my code appears to be within the range?
I was coding a project called "My Countdown Calendar".我正在编写一个名为“我的倒计时日历”的项目。 I was almost done and so I gave what I had so far a test run.我快完成了,所以我给了我到目前为止的测试运行。 I ended up getting this error.我最终得到了这个错误。 Here is my code.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)
When parsing a text file, you'll almost always want to skip empty lines.解析文本文件时,您几乎总是想跳过空行。 Here's an idomatic pattern for this:这是一个 idomatic 模式:
for line in file:
line = line.strip()
if not line:
continue
# process line
If your file format depends on whitespace on the non-empty lines, you can join lines 2 and 3 to if not line.strip()
.如果您的文件格式取决于非空行上的空格,您可以将第 2 行和第 3 行连接到if not line.strip()
。
