• Python File Tagging System does not retrieve nested dictionaries in dictionary

  I am building a file tagging system using Python. The idea is simple. Given a directory of files (and files within subdirectories), I want to filter them out using a filter input and tag those files with a word or a phrase.

  If I got the following contents in my current directory:

  data/
     budget.xls
     world_building_budget.txt
  a.txt
  b.exe
  hello_world.dat
  world_builder.spec
  

  and I execute the following command in the shell:

  py -3 tag_tool.py -filter=world -tag="World-Building Tool"
  

  My output will be:

  These files were tagged with "World-Building Tool":
  data/ world_building_budget.txt
  hello_world.dat
  world_builder.spec
  

  My current output isn't exactly like this but basically, I am converting all files and files within subdirectories into a single dictionary like this:

  def fs_tree_to_dict(path_):
      file_token = ''
      for root, dirs, files in os.walk(path_):
          tree = {d: fs_tree_to_dict(os.path.join(root, d)) for d in dirs}
          tree.update({f: file_token for f in files})
          return tree
  

  Right now, my dictionary looks like this: key:''.

  In the following function, I am turning the empty values '' into empty lists (to hold my tags):

  def empty_str_to_list(d):
      for k,v in d.items():
          if v == '':
              d[k] = []
          elif isinstance(v, dict):
              empty_str_to_list(v)
  

  When I run my entire code, this is my output:

  hello_world.dat ['World-Building Tool']
  world_builder.spec ['World-Building Tool']
  

  But it does not see data/world_building_budget.txt. This is the full dictionary:

  {'data': {'world_building_budget.txt': []},  
  'a.txt': [],
  'hello_world.dat': [], 
  'b.exe': [], 
  'world_builder.spec': []}
  
  

  This is my full code:

  import os, argparse
  
  
  def fs_tree_to_dict(path_):
      file_token = ''
      for root, dirs, files in os.walk(path_):
          tree = {d: fs_tree_to_dict(os.path.join(root, d)) for d in dirs}
          tree.update({f: file_token for f in files})
          return tree
  
  
  def empty_str_to_list(d):
      for k, v in d.items():
          if v == '':
              d[k] = []
          elif isinstance(v, dict):
              empty_str_to_list(v)
  
  
  parser = argparse.ArgumentParser(description="Just an example", formatter_class=argparse.ArgumentDefaultsHelpFormatter)
  
  parser.add_argument("--filter", action="store", help="keyword to filter files")
  parser.add_argument("--tag", action="store", help="a tag phrase to attach to a file")
  parser.add_argument("--get_tagged", action="store", help="retrieve files matching an existing tag")
  
  args = parser.parse_args()
  
  filter = args.filter
  tag = args.tag
  get_tagged = args.get_tagged
  current_dir = os.getcwd()
  
  files_dict = fs_tree_to_dict(current_dir)
  empty_str_to_list(files_dict)
  
  for k, v in files_dict.items():
      if filter in k:
          if v == []:
              v.append(tag)
              print(k, v)
  
          elif isinstance(v, dict):
              empty_str_to_list(v)
  
      if get_tagged in v:
          print(k, v)

• Looping the function if the input is not string

  I'm new to python (first of all) I have a homework to do a function about checking if an item exists in a dictionary or not.

  inventory = {"apple" : 50, "orange" : 50, "pineapple" : 70, "strawberry" : 30}
  
  def check_item():
      x = input("Enter the fruit's name: ")
      if not x.isalpha():
          print("Error! You need to type the name of the fruit")
      elif x in inventory:
          print("Fruit found:", x)
          print("Inventory available:", inventory[x],"KG")
      else:
          print("Fruit not found")
  check_item()
  

  I want the function to loop again only if the input written is not string. I've tried to type return Under print("Error! You need to type the name of the fruit") but didn't work. Help

  im not too sure how you add a loop statement to this. I want it to be a while loop that makes it do that the calculations repeat after finishing.

• Data structure for iterating between players

  I am new to programming, so I started working on a small guessing game for n players In theory they are supposed to take turns trying to guess some String, I've successfully implemented that game for 1 player, but now I am struggling with how to implement iterating over all players. My code right now looks something like this:

  while (!gameIsFinished) {
      gameIsFinished = player1.takeTurn();
  }
  

  I guess I have to use some sort of Data structure to store all my players, but what would I choose in order to be able to iterate over them in a loop?

• How to use Tkinter after method to give the impression of a wheel spinning?

  I'm trying to create three separate 'wheels' that change the starting position of the first arc in order to give the impression of the wheel spinning. Tkinter will draw the first wheel on the canvas and delete it after 1 second, but the subsequent wheels are never drawn.

      from tkinter import Canvas, Tk
  
      tk = Tk()
      tk.geometry('500x500')
  
      canvas = Canvas(tk)
      canvas.pack(expand=True, fill='both')
  
      in_list = [1,1,1,1,1,1,1]
  
      arc_length = 360 / len(in_list)
      first_mvmt = arc_length / 3
      second_mvmt = arc_length * 2 / 3
  
      mvmt_list = [0, first_mvmt, second_mvmt]
  
      for mvmt in mvmt_list:
          for i in range(len(in_list)):
              start = i * arc_length
              extent = (i + 1) * arc_length
              arc = canvas.create_arc(5, 5, 495, 495, outline='white', start=start + mvmt, extent=extent)
  
          canvas.after(1000)
          canvas.delete('all')
  
  
      tk.mainloop()
