以下是我的代码:
with open("WinUpdates.txt") as f:
data=[]
for elem in f:
data.append(elem)
with open("checked.txt", "w") as f:
check=True
for item in data:
if "KB2982791" in item:
f.write("KB2982791\n")
check=False
if "KB2970228" in item:
f.write("KB2970228\n")
check=False
if "KB2918614" in item:
f.write("KB2918614\n")
check=False
if "KB2993651" in item:
f.write("KB2993651\n")
check=False
if "KB2975719" in item:
f.write("KB2975719\n")
check=False
if "KB2975331" in item:
f.write("KB2975331\n")
check=False
if "KB2506212" in item:
f.write("KB2506212\n")
check=False
if "KB3004394" in item:
f.write("KB3004394\n")
check=False
if "KB3114409" in item:
f.write("KB3114409\n")
check=False
if "KB3114570" in item:
f.write("KB3114570\n")
check=False
if check:
f.write("No faulty Windows Updates found!")
“WinUpdates.txt”文件包含很多这样的行:

但是当我执行我的代码时,它说它没有找到任何这些更新?即使我知道它应该找到4。 我将“数据”列表写入一个新的文本文件,但似乎一切都好吗?
为什么你认为我的代码不起作用?

FWIW,您的代码可以用更紧凑的方式编写,不需要大量if
语句。此外,由于(新)数据文件只有63342字节,您可以将整个内容读入单个字符串,而不是字符串列表。
kb_ids = (
"KB2982791",
"KB2970228",
"KB2918614",
"KB2993651",
"KB2975719",
"KB2975331",
"KB2506212",
"KB3004394",
"KB3114409",
"KB3114570",
)
with open("WinUpdates.txt") as f:
data = f.read()
check = True
with open("checked.txt", "w") as f:
for kb in kb_ids:
if kb in data:
f.write(kb + "\n")
check = False
if check:
fout.write("No faulty Windows Updates found!\n")
checked.txt 的内容,使用链接数据:
KB2970228
KB2918614
KB2993651
KB2506212
KB3004394
请注意,此代码按照kb_ids
中定义的顺序打印找到的kbids,而不是它们在" WinUpdates.txt"中出现的顺序。
如果文件很大,例如超过一兆字节左右,那么搜索整个文件作为每个kbid的字符串可能不是个好主意;您可能希望运行一些时序测试(使用timeit
)来查看哪种策略最适合您的数据。
如果您想将文件读入列表,则无需使用for
循环,您可以这样做:
with open("WinUpdates.txt") as f:
data = f.readlines()
或者,您可以逐行处理文件而不将其读入列表:
kb_ids = (
"KB2982791",
"KB2970228",
"KB2918614",
"KB2993651",
"KB2975719",
"KB2975331",
"KB2506212",
"KB3004394",
"KB3114409",
"KB3114570",
)
check = True
with open("WinUpdates.txt") as fin:
with open("checked.txt", "w") as fout:
for data in fin:
for kb in kb_ids:
if kb in data:
fout.write(kb + "\n")
check = False
if check:
fout.write("No faulty Windows Updates found!\n")
在更现代的Python版本中,两个with
statements可以组合成一行。

我添加并修复了您丢失的内容,请检查两条评论,看看我的意思。这对我有用,所以它应该适合你。祝你有美好的一天!
