• 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

• AWS Pinpoint sendMessages() Addresses param field error

  I'm having trouble replicating the format of the params object's Addresses format in a way where I can easily add to the object.

  If I use this as the params with destinationNumber[0] and destinationNumber[1] in the format of 1 + 9 digit number ie 13334535667 then it sends the message to both numbers no problem.

   const params = {
          ApplicationId: applicationId,
          MessageRequest: {
              Addresses: {
                  [destinationNumber[0]]: {
                      ChannelType: 'SMS'
                  },
                  [destinationNumber[1]]: {
                      ChannelType: 'SMS'
                  }
              },
              MessageConfiguration: {
                  SMSMessage: {
                      Body: message,
                      Keyword: registeredKeyword,
                      MessageType: messageType,
                      OriginationNumber: originationNumber
                  }
              }
          }
      };
  

  I'm trying to replicate this format for Addresses, but I'm getting Unexpected key '13334535667' found in params.MessageRequest.Addresses['0']. The format my console output shows for Addresses is

  [
    { '12345678910': { ChannelType: 'SMS' } },
    { '12345678911': { ChannelType: 'SMS' } }
  ]
  

  I'm using a map to call this

  function createPhoneMessagingObject(phoneNumber: string) {
      return {
          [phoneNumber]: {
              ChannelType: 'SMS'
          }
      };
  }
  

  I tried wrapping key in array like in phone object, but per the output, the brackets goes away so maybe there's an easier/more correct way of doing this. I appreciate any help!
• Assign ELB Account to S3 Bucket Policy

  I used the AWS console from the load balancer edit attributes screen and used it to create a bucket to use for access logging. I'm using this policy to form CDK code in typescript to stand up new S3 buckets to use for access logging in higher level environments where I cannot use the console. This is the policy I need to somehow form in typescript CDK code:

  "Statement": [
  {
      "Effect":Allow",
      "Principal": {
          "AWS": "arn:--ELB-arnstuff--:root"
      },
      "Action": "s3:PutObject",
      "Resource": "arn:--S3-Bucket-arnstuff--/AWSLogs/123456789/*"
  }
  ]
  

  I've managed to get the cdk code figured out to this point:

  bucket.addToResourcePolicy(
      new cdk.aws_iam.PolicyStatement({ 
        effect: awsIam.Effect.ALLOW,
        principals: //'**This is part I haven't figured out**',
        actions: ['s3:PutObject'],
        resources: ['${bucket.bucketArn}/*']
      })
  );
  

  At this point I don't care if it's hard coded in the CDK, I just need something to help keep the ball rolling forward. Any help is appreciated, thanks
• How can I get file metadata like the date created attribute from an S3 file?

  I have a lot of LogicPro files (.logicx) stored in an S3 bucket, and I want to extract the creation date from all of these files. This should not be the creation date of the object on s3, but the date for when it was created on my MacBook (the "Created" attribute in Finder).

  I've tried to retrieve the metadata from the object using the HEAD action:

  aws s3api head-object --bucket <my-bucket> --key <my-object-key>
  

  The output did not contain any information about the creation date of the actual file.

  {
     "AcceptRanges":"bytes",
     "LastModified":"2021-10-28T13:22:33+00:00",
     "ContentLength":713509,
     "ETag":"\"078c18ff0ab5322ada843a18bdd3914e\"",
     "VersionId":"9tseZuMRenKol1afntNM8mkRbeXo9n2W",
     "ContentType":"image/jpeg",
     "ServerSideEncryption":"AES256",
     "Metadata":{},
     "StorageClass":"STANDARD_IA"
  }
  

  Is it possible to extract the file creation metadata attribute from an S3 object, without having to download the whole object?
