如何读取 Python 中已排序和设置的文本文件？

Question

我是 python 的新手，遇到了我正在读取文本文件并删除不需要的内容并使用 sorted-set 写入新文本文件的问题。然后我需要阅读新的文本文件并继续进行下一步编码。但是当我读取文件时，它的读数是从新文本文件中跳过最后 40 行。

请在下面找到我的编码

f3 = open("data/new.txt", "w")
uniqueperm = []
with open("data/read1.txt", "r") as ins:
    d = ins.readlines()
    for line in d:
    #print(line)

        if 'blab: name=' and 'blab1' in line:

            line = str(line.replace("blab: name= ", "").replace("'", "").replace("\n", ""))
            line = str(line.replace("blab1: ", "").replace("'", "").replace("\n", ""))
            #print(line)
            uniqueperm.append(line)
            #print((line))

for pop in (sorted(set(uniqueperm))):
#print(pop)
f3.write(pop + "\n")

packages = os.listdir("./data/")
inss = open("data/new.txt", 'r').read().split("\n")
print(inss)

output inss 从新文本文件中逐行读取，但跳过新文本文件中的最后 40 奇数行。请有人帮助我解决这个问题。提前致谢:)

#read1.txt file contains 

blab1: cool.add.WEATHER_ALL
blab1: warm:add.WEATHER_EVERYWHERE
blab: name= hello.add.COPY_HI
blab: name= hello.add.ACCESS_HELLO
blab: name= hello.add.ADD_HI
blab: name= hello.add.WRITE_HI
.
.
.
#it also include repeated data as above so i used set() option so the duplicates are removed before writing to new.txt file 

#new.txt file contains

hello.add.ACCESS_HELLO
hello.add.ADD_HI
hello.add.COPY_HI
hello.add.WRITE_HI
cool.add.WEATHER_ALL
warm.add.WEATHER_EVERYWHERE
.
.
.

#new.txt file contains all the data from read1.txt

#when i read this new.txt file in terminal the output is

hello.add.ACCESS_HELLO
hello.add.ADD_HI
hello.add.COPY_HI
hello.add.WRITE_HI
cool.add.WEATHER_ALL

#remaining its skipping or not reading to further proceed

您检查子字符串的条件不正确：

if 'blab: name=' and 'blab1' in line:

将分别检查 'blab: name=' 和 'blab1' in line（条件的和部分都需要成立）。你想要的是：

if 'blab: name=' in line or 'blab1' in line:
