sorted function (list/tuple) working wrongly in reverse order

Tag : python , By : keird

wish helps you It appears to be working correctly. You're sorting by strings and, alphabetically, '8%' is considered greater than '26%'. You may find this more useful as your lambda:
lambda x : float(x[1].strip('%'))

Will you get descending order if you reverse list of objects which is sorted by ascending order?

Hope that helps Yes, reversing a list, that is sorted in ascending order, will give you list that is sorted in descending order.
However, it may not give you the same result as sorting a list in descending order.

wish help you to fix your issue Scanning the Sorted Set with an iterator does not guarantee any order. Use ZREVRANGEBYSCORE for that.

Python - printing out a trie in alphabetically sorted order with a recursive function

it helps some times I'm working my way through the NLTK book by Bird, Klein, and Loper and I'm stuck on a problem. I'm working through the book for my own personal enrichment, and not for a class.
def insert(trie, key, value):
    """Insert into Trie"""
    if key:
        first, rest = key[0], key[1:]
        if first not in trie:
            trie[first] = {}
        insert(trie[first], rest, value)
        trie['value'] = value

def display(trie, s = ""):
  """Recursive function to Display Trie entries in alphabetical order"""
  first = True
  for k, v in sorted(trie.items(), key = lambda x: x[0]):
    # dictionary sorted based upon the keys
    if isinstance(v, dict):
      if first:
        prefix = s + k          # first to show common prefix
        first = False
        prefix = '-'*len(s) + k  # dashes for common prefix

      display(v, prefix)   # s+k is extending string s for display by appending current key k
      print(s, ":", v)  # not a dictionary, so print current   # not a dictionary, so print current string s and value

# Create Trie
trie = {}
insert(trie, 'chat', 'cat')
insert(trie, 'chien', 'dog')
insert(trie, 'chair', 'flesh')
insert(trie, 'chic', 'stylish')

#Display Use Recursive function (second argument will default to "" on call)
chair : flesh
---t : cat
--ic : stylish
---en : dog
