Removing \r\n from a Python list after importing with readlines

Question

I have saved a list of ticker symbols into a text file as follows:

MMM
ABT
ABBV
ANF
....

Then I use readlines to put the symbols into a Pyt

Answer 1

That's basically how readlines works. You could post-process it:

stocks = [x.rstrip() for x in stocks]

But I prefer not using readlines at all if I don't want EOL character(s), instead doing:

stocks = open(textfile).read().splitlines()

Or even better:

with open(textfile) as f:
    stocks = f.read().splitlines()

(it almost certainly won't make a difference here, but using context managers to explicitly close file objects is a good habit to get into)
