• 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
• Rotate and translate image from center to all directions one by one in ios swift

  I am trying to make a demo of animation for learning but i am having issue regarding coordinate system of apple and how does it work when trying for animations. The issue is i have 6 static images stacked upon each other as pile of playing cards and have 6 empty views in all directions which is of same height and width as the pile cards height width. Now how do i rotate and translate card 6 to bottomleft then card 5 to topleft then card 4 to top center card3 to topright then card 2 to bottom right and card1 to bottom center i.e more like a playing card distribution animation

• Javascript request animation frame irregular translation

  SO community! I'm trying to make an object move at the same phase as scroll using CSS transform. The problem is that I see the animation is not smooth. Instead, is like the box is flickering and 'jumping' all the time, and I can't figure out the cause.

  How can I achieve these kinds of transformations in a smooth way?

  I will leave my code below, as well as a codepen link.

  Thanks beforehand for your help!

  const container = document.querySelector('.container');
  const box = document.querySelector('.box');
  
  function animate() {
    transformBox();
    requestAnimationFrame(animate);
  }
  
  function transformBox() {
    const scrollY = window.scrollY;
    box.style.transform = `translate3d(0, ${scrollY}px, 0)`;
  }
  
  animate();

    margin: 0;
    padding: 0;
    box-sizing: border-box;
  }
  
  html, body {
    overscroll-behavior: none;

• How to make xlim and ylim dynamically change?

• Animating grid with FuncAnimation converges almost immediately to a single color

  I am modeling phase separation in python. When I use matplotlib's FuncAnimation, the grid converges to the same color almost immediately. When I use a simple loop and redraw on each iteration, the simulation evolves as I would expect. I would prefer to use FuncAnimation if possible.

  In this code, the grid is all purple within a second or so

  fig, ax = plt.subplots()
  
  im1 = ax.imshow(self.grid)
  animation.FuncAnimation(fig,
                          self.my_update_func
                          100000
                          init_func = self.my_init_func,
                          repeat = False,
                          blit=True,
                          fargs=(im1,),
                          interval = 100)
  plt.show()
  
  my_update_func(self, i, img)
      self.update_grid()
      img.set_data(self.grid)
      return img,
  

  Whereas in this code the animation evolves as a phase separation simulation would be expected to do:

  for i in range(1,100000):
      self.upgrade_grid()
      if i % 1000 == 0:
          plt.imshow(self.grid, animated=True, cmap='plasma')
          plt.draw()
          plt.pause(0.001)
  

  Can someone please tell me why the FuncAnimation method is not working?

  Thank you
