Python rstrip and split

Hope this helps It should be split_file.split(' ') instead of line.split(' '), and also you need to do the line.rstrip() before the split_file.split(' '):
code :
just_compound_id = []
for line in final_list:
    split_file = line.rstrip()
    split_file = split_file.split(' ')

I hope this helps you . ruby: What is the most optimized expression to evaluate the same as result as with , Optimised for clarity I would prefer the following:
code :
require "benchmark"

# Adjust parameters below for your typical use case.
n = 10_000
input = " This is - an example. - A relatively long string " +
  "- delimited by dashes. - Adjust if necessary " * 100
delimiter = "-"

Benchmark.bmbm do |bench|
  bench.report "collect { |s| s.lstrip.rstrip }" do
    # Your example.
    n.times { input.split(delimiter).collect { |s| s.lstrip.rstrip } }

  bench.report "collect { |s| s.strip }" do
    # Use .strip instead of .lstrip.rstrip.
    n.times { input.split(delimiter).collect { |s| s.strip } }

  bench.report "collect { |s| s.strip! }" do
    # Use .strip! to modifiy strings in-place.
    n.times { input.split(delimiter).collect { |s| s.strip! } }

  bench.report "collect(&:strip!)" do
    # Slow block creation (&:strip! syntax).
    n.times { input.split(delimiter).collect(&:strip!) }

  bench.report "split(/\\s*\#{delim}\\s*/) (static)" do
    # Use static regex -- only possible if delimiter doesn't change.
    re = Regexp.new("\s*#{delimiter}\s*")
    n.times { input.split(re) }

  bench.report "split(/\\s*\#{delim}\\s*/) (dynamic)" do
    # Use dynamic regex, slower to create every time?
    n.times { input.split(Regexp.new("\s*#{delimiter}\s*")) }
                                      user     system      total        real
collect { |s| s.lstrip.rstrip }   7.970000   0.050000   8.020000 (  8.246598)
collect { |s| s.strip }           6.350000   0.050000   6.400000 (  6.837892)
collect { |s| s.strip! }          5.110000   0.020000   5.130000 (  5.148050)
collect(&:strip!)                 5.700000   0.030000   5.730000 (  6.010845)
split(/\s*#{delim}\s*/) (static)  6.890000   0.030000   6.920000 (  7.071058)
split(/\s*#{delim}\s*/) (dynamic) 6.900000   0.020000   6.920000 (  6.983142)

wish helps you I have a tuple that looks like this: , You could use a list comprehension:
code :
rows = [row.split() for row in your_tuple]
>>> '    a    b  c \t\n\n   '.split()
['a', 'b', 'c']

this will help As mentioned in the comments a set would be better for this but since the assignment is about lists, try something like this:
code :
list_of_words = []
with open('romeo.txt') as f:
    for line in f:
        words = line.split()
        for word in words:
            if word not in list_of_words:

sorted_list_of_words = sorted(list_of_words)
print(' '.join(sorted_list_of_words))
Arise But It Juliet Who already and breaks east envious fair grief is kill light moon pale sick soft sun the through what window with yonder
fname = raw_input('Enter file: ')

wordlist = list()
for line in open(fname, 'r'):
    words = line.split()
    for word in words:
        if word in wordlist: continue

print ' '.join(wordlist)
Enter file: romeo.txt
Arise But It Juliet Who already and breaks east envious fair grief is kill light moon pale sick soft sun the through what window with yonder

it fixes the issue The rstrip() in Python takes a set of characters as the argument.
If no argument is provided, the default is a whitespace.
TypeError: rstrip arg must be None or str: Python 3

this one helps. You are passing an integer to rstrip, you must pass None or some character, if this character is what you want to remove from the right-hand side of the string.
