How to read all the files of a directory in python and save file data in a dictionary

I have many documents in a folder. They in thousands in a .txt format. I want to read all of those documents and want to store documents content in a dictionary. The key of dictionary can be documents name and value should be content of that particular document. But right now I am only able to print all the names of my files but not able to make a dictionary where its content can be stored. I have written this code:

import os
with os.scandir('docs/') as entries:
    for entry in entries:
        print(entry.name)
        with open('F:\folder\docs\'+entry.name) as f:
            contents = {'entry.name': f.read()}

Or if you can give me some new method to read content from all the files and then store it in a dictionary. Please help me in this regard. Thank you.

This way it should work.

import os

docs_dict = {}

with os.scandir('docs/') as entries:
    for entry in entries:
        print(entry.name)
        with open('F:/folder/docs/'+ entry.name ) as f:
          val = f.read()
          docs_dict[f.name] = val
          f.close()

I created an empty dictionary outside the for loop. Then, expanding your code, I stored the content of the document in val and then added the dictionary item. I also changed F:\folder\docs\ to F:/folder/docs/, cause Python wants forward slashes in paths, and using \ excludes the ending quote of the string.

my solution:

import os
import json


all_files = dict()
with os.scandir() as entries:
    for entry in entries:
        print(entry.name)
        with open(rf'{entry.name}') as f:
            contents = f.read()
        all_files[f'{entry.name}'] = contents
        
with open('all_files.json', 'w') as f:
    json.dump(all_files, f, indent=2)

assuming the loop in the code you have posted works - the code below should create the dict you are looking for.

import os
data = {}
with os.scandir('docs/') as entries:
    for entry in entries:
        with open('F:\folder\docs\'+entry.name) as f:
            data[entry.name] = f.read()
