How to get path of selected files in a folder using python?

Question

I am using glob to retrieve the path of all files in a folder ("data"):

import glob
import geopandas

for file in glob.glob(r"/home/data/*.txt"):
    sf = geopandas.read_file(file)

However, here, I am interested in knowing how to retrieve only selected files whose names are listed in a variable as a list. For instance, I want the path of only the following files: aaa.txt, bdf.txt, hgr.txt, in the "data" folder, which are listed in variable "imp".

imp = ['aaa.txt', 'bdf.txt', 'hgr.txt']

so you are basically looking for r"/home/data/aaa.txt", r"/home/data/bdf.txt" and r"/home/data/hgr.txt"? If yes, why you need the glob then? — niaei

Actually, there are hundreds of such files of interest, not just three, that have to be chosen from thousands of files in a folder. — Gun

Ok then you are looking for files like aaa.txt? Is it like *aaa.txt or *aaa*.txt? — niaei

Files' name does not follow any pattern. Instead, I want to read the path of all files whose names are available as a list stored in a variable "imp". — Gun

Something like this could do it. Just loop through the files you need.

import geopandas

imp = ['aaa.txt', 'bdf.txt', 'hgr.txt']
for file in imp:
    sf = geopandas.read_file(f'/home/data/{file}')

Unfortunately I cannot edit the answer since it's smaller then 6 characters. Your quote sign is in wrong place. f"/home/data/"{file}

@MSH I was able to fix it.

Like this?

import geopandas

path = "/home/data/"
imp = [ 'aaa.txt', 'bdf.txt', 'hgr.txt']
for file in imp:
    if os.path.exists(path+file):
        sf = geopandas.read_file(path+file)
