Python rstrip and split


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(' ')
    just_compound_id.append(split_file[2])
    print(just_compound_id)

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 :
phrase.split(delimiter).collect(&:strip)
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 } }
  end

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

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

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

  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) }
  end

  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*")) }
  end
end
                                      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:
                list_of_words.append(word)

sorted_list_of_words = sorted(list_of_words)
print(' '.join(sorted_list_of_words))

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
        wordlist.append(word)

wordlist.sort()
print ' '.join(wordlist)
Enter file: romeo.txt

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.
