Python seemingly not reading from text file

Question

files = []
with open("[...].log", "a+") as posshell:
    for line in files:
        print(line)
        posshell_files.append(line)

I have no clue. It prints nothing. The array is empty. I've tried grabbing every null character and removing them in case it's UTF16 -> open as UTF8, didn't work.

If you want to read and write use `r+`. https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files — Anthon, Jul 06 '17 at 14:21

You are passing the incorrect second argument to the open call to read the file in this way:

posshell_files = []
with open("posshell.log", "r") as posshell:
    for line in posshell:
        print(line)
        posshell_files.append(line)

According to the Python docs for open, 'r' if the default flag for reading while 'a+' is for reading and writing but you will have to do so in a different manner:

with open("posshell.log","a+") as f:
    f.seek(0)
    print(f.read())

See https://stackoverflow.com/a/1466036/3282436 for a pretty good explanation of file modes – 0x5453 Jul 06 '17 at 14:21
This worked but my understanding is that I was using one that should be a catch all. edit; thanks for the link – Dylan Moore Jul 06 '17 at 14:23
@DylanMoore see edits above for more detail, but the link from 0x5453 is a nice summary – Daniel Corin Jul 06 '17 at 14:24

Try this

with open('posshell.log') as p:
    content = p.readlines()
    content = [x.strip() for x in content]
