尝试通过查找文档ID来创建字典文件和发布列表文件。它应该打开文件并搜索术语' .I'并将该行作为列表元素
#Function which find the doc ID
#There is a list I created with name idList
def idTag():
file = open('cacm.txt', 'r')
line = file.readline()
while line:
if '.I' in line:
idList.append(line)
elif not '.I' in line:
line = file.readline()
elif not line:
file.close()`
答案 0 :(得分:3)
我不太明白你要做什么,但是如果我正确地阅读了这个问题,你想迭代文件的行,过滤那些包含字符串'.I'
的文件。因此,这应该有效:
def idTag():
# Create the list to collect the results in
idList = []
# Better way of opening a file;
# closes it automatically when the `with` statement is finished
with open('cacm.txt', 'r') as file:
# Read each line from the file
for line in file:
# Filter those that have `.I` in them
if '.I' in line:
idList.append(line)
return line
这利用了以下事实:文件可以循环,一次读取一行。
