我制作一个读取.txt文件的脚本，然后继续使用该信息和日期来创建动态html文件。它在昨天工作，但今天，似乎它不想写任何文件...
这是源代码。

它写入名为index.html的文件。我认为问题出在Try语句中，但我试图删除它并且它没有以任何方式影响它。
谢谢。
答案 0 :(得分：1)
1）确保它符合任何方案。你没有else条件如下，你的timeserino可能不符合1-7场景中的任何一个
if timeserino == 1:
# write something
elif timeserino ==2:
# write something
...
elif timeserino == 7:
# write something
else:
write something
2）完成写作后关闭文件

你的根本问题是你的功能太长而且复杂，你无法调试它（或理解它失败的原因）。
使意图更清晰的简单重构就像经常使用的命名表达式（例如datetime.datetime.today()）和使用数组从序列中选择某些东西而不是if-statements的长级联：
today = datetime.datetime.today()
weekday = today.weekday()
dagnavn = ['Mandag', 'Tirsdag', 'Onsdag', 'Torsdag', 'Fredag', u'Lørdag', u'Søndag']
dag = dagnavn[weekday]
然后明天可以同样选择：
imorgen = dagnavn[(weekday + 1) % 7]
从if语句中删除了dag和imorgen，可以使用daynames而不是工作日数字以更具描述性的方式分配daginfo：
daginfo = {
'Mandag': "Matte\n" + "Naturfag\n" + "Engelsk\n" + "ToF\n",
'Tirsdag': "...",
...
}[dag]
到目前为止，您的代码是一个＆＃34; unit＆＃34;可以独自站立（你似乎通过类似段落的间距本能地理解）。它应该被拉出一个单独的功能，以便原始功能变得更小，更容易推理（一个功能通常不应该长于你可以适应屏幕而不滚动）。函数看起来像：
# dagnavn is a constant and should be defined at module level
dagnavn = ['Mandag', 'Tirsdag', 'Onsdag', 'Torsdag', 'Fredag', u'Lørdag', u'Søndag']
def get_schedule(date):
weekday = date.weekday()
dag = dagnavn[weekday]
imorgen = dagnavn[(weekday + 1) % 7]
daginfo = {
'Mandag': "Matte\n" + "Naturfag\n" + "Engelsk\n" + "ToF\n",
...
}[dag]
return dag, imorgen, daginfo
然后你将删除filerino()中的long if语句并将其替换为：
dag, imorgen, daginfo = get_schedule(today) # still assuming you've created the `today` variable
如果你继续拔出代码＆＃34;单位＆＃34;像这样进入他们自己的功能，你最终会得到一个更小的功能来展示你的问题。那个较小的函数就是你通常在SO上的一个问题中发布的（这是代表你的问题的最小代码片段）。
