Build All The Things II

Published December 5, 2018 in Programming - 1 min to read

First small Python programme written! It is pretty easy to output just 'hello world', so I did it three different ways. I learned about:

Importing modules;
Tuples, lists and sets;
How to sort and remove duplicates from a list;
Using sys.stdout.write vs print().

Personally I think this is a good start, especially for half an hour's work. Here's the code, check it works!

    
      import sys

      print('hello world')

      characters = [ 'h', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd']
      for x in characters:
          sys.stdout.write(x)

      sorted_characters = list(set(characters))
      sorted_characters.sort()
      print("")
      sys.stdout.write(sorted_characters[3])
      sys.stdout.write(sorted_characters[2])
      sys.stdout.write(sorted_characters[4])
      sys.stdout.write(sorted_characters[4])
      sys.stdout.write(sorted_characters[5])
      sys.stdout.write(sorted_characters[0])
      sys.stdout.write(sorted_characters[7])
      sys.stdout.write(sorted_characters[5])
      sys.stdout.write(sorted_characters[6])
      sys.stdout.write(sorted_characters[4])
      sys.stdout.write(sorted_characters[1])
