I have 10 data in txt format: a1.txt,a2.txt,...,a10.txt and I want to load them one by one in a for loop.
To load a file I use
data = read_data('a1.txt');
but I am not sure how to use it in a for loop.

Start by asking yourself, what part should change on each iteration of the loop?Code-Apprentice– Code-Apprentice2019-10-22 23:28:47 +00:00Commented Oct 22, 2019 at 23:28

Search for files inside path that end with .txt
from os import listdir
from os.path import isfile, join
mypath='/tmp'
files = [f for f in listdir(mypath) if isfile(join(mypath, f)) and f.endswith('.txt')]
Another approach with pathlib (python 3.4+). It recognizes also the a for matching:
from pathlib import Path
files = [str(f) for f in Path(mypath).iterdir() if f.match("a*.txt")]

Use the range() function to generate a sequence of numbers, and then use string formatting to assemble the filename:
for number in range(1, 11):
filename = 'a%d.txt' % number
data = read_data(filename)

If you have the txt files in a folder you could read the entire folder and loop through the txt files in it.
import glob
folder_path = 'path/to/the/folder'
for filename in glob.glob(folder_path, '*.txt')):
#Your process for each file
