Remove all \n from end of list items

[JackMack118]

Hello yes because I set it as a proxy for requests. I've been doing all the strip methods, string strip methods and keep getting all the errors I mentioned in the OP.

I think it's because it's not turning into a list because of the double [[]], that's why the stripping is bringing errors.

OK, I have a working example but I open file 3 times which is probably not a good idea for speed. What I need to do is get 200 lines from a text file into a list, and delete those 200 lines simultaneously.

Anyway this works, but I think it's not best:

with open("sample.txt") as myfile:
    res = [next(myfile).strip() for x in range(200)]
with open('sample.txt', 'r') as fin:
    data = fin.read().splitlines(True)
with open('sample.txt', 'w') as fout:
    fout.writelines(data[200:])
print(res)

Ok, keep answering my own post, I've slimmed down, this works best.

with open('sample.txt', 'r') as fin:
    res = [next(fin).strip() for x in range(200)]
    data = fin.read().splitlines(True)
with open('sample.txt', 'w') as fout:
    fout.writelines(data[200:])
print(res)
