I Selected my needed Data Like This:

import pathlib
from pathlib import Path
import glob, os

folder = Path('D:/xyz/123/Files')

os.chdir(folder)
for file in glob.glob("*.json"):
    JsonFiles = os.path.join(folder, file)
    print (JsonFiles)

As Output I will get all my needed .json Files

D:/xyz/123/Files/Data.json
D:/xyz/123/Files/Stuff.json
D:/xyz/123/Files/Random.json
D:/xyz/123/Files/Banana.json
D:/xyz/123/Files/Apple.json

For my further coding in need a Variable to the diffrens Json Paths. So my Idear was insted of printing them to store them in a List. But thats not working?

ListJson =[JsonFiles]
print (ListJson[1])

I get this Error:

print (ListJson[2])
IndexError: list index out of range

How wold you solve this Problem I just need an possibility to work with the Paths I already sorted.

Solution 1 with append():

If you change

for file in glob.glob("*.json"):
    JsonFiles = os.path.join(folder, file)
    print (JsonFiles)

to

ListJson = []
for file in glob.glob("*.json"):
    JsonFile = os.path.join(folder, file)
    ListJson.append(JsonFile)

You create an empty list and add during each iteration one file (the result of os.path.join to it.

then you would have what you want

Solution 2 with list comprehensions:

If you want to use list comprehensions ( https://docs.python.org/3/tutorial/datastructures.html#list-comprehensions ) , then following would do:

ListJson = [os.path.join(folder, file) for file in glob.glob("*.json")]

Solution 3: with pathlib, absolute() and glob():

On the other hand you don't even have to chdir() into the given directory and if path objects are good enough in your context you could directly do:

ListJson = list(folder.absolute().glob('*.json'))

or if you really need strings:

ListJson = [str(path) for path in folder.absolute().glob('*.json')]

You can use Python List append() Method

import pathlib
from pathlib import Path
import glob, os

folder = Path('D:/xyz/123/Files')
ListJson=[]
os.chdir(folder)
for file in glob.glob("*.json"):
    JsonFiles = os.path.join(folder, file)
    ListJson.append(JsonFiles)

print(ListJson)
